Acer Aspire 5551 Key Features

The Acer Aspire 5551 is one of the first laptops we’ve seen with a triple-core processor – most laptops have dual-core processors.

The 15.6in widescreen display is bright, with reasonably accurate colours and good contrast. The screen tilts back so it almost lies parallel to the keyboard, so it’s comfortable to use when placed on your lap. White images do have a slight blueish tint, though, while the backlight is a little uneven and viewing angles are tight, so the appearance of colours can shift subtly depending on where you sit. It’s good enough for everyday tasks where colour accuracy isn’t paramount.

In fact it’s not that much more impressive than Intel’s integrated graphics efforts, in that it too won’t allow you to play even basic 3D games like TrackMania Nations Forever at decent settings. Still, it does a good job of video acceleration and processing, taking that load off the CPU.

Acer 5551: Multimedia Powerhouse

Enjoy multimedia brilliance, power and performance with the Acer Aspire 5551 notebook PC, which features a vivid 15.6-inch HD widescreen CineCrystal LED-backlit display. The dual-core AMD Turion II processor and 4 GB of DDR3 RAM accelerate all your daily needs with the multitasking performance and responsiveness needed to download music, launch movies, chat and complete your daily tasks.

The notebook’s rounded edges and smooth lines bring a slenderized look while the textured mesh silver cover brings a rich appearance and prevents fingerprints and scratches. Other features include a multi-gesture trackpad, dedicated numeric keypad, 1.3-megapixel HD webcam, and Wireless-N Wi-Fi connectivity.

Pre-installed with the Microsoft Windows 7 Home Premium operating system (64-bit version), you’ll be able to easily create a home network and share all of your favorite photos, videos, and music. Windows 7 is the easiest, fastest, and most engaging version of Windows yet. Better ways to find and manage files, like Jump Lists and improved taskbar previews, help you speed through everyday tasks. Windows 7 is designed for faster and more reliable performance, so your PC just works the way you want it to.

Acer Aspire 551 battery life

ACER Aspire 5551 Battery from www.laptopbatteryshop.ca

Battery life from the Aspire 5551′s 4,400mAh/48Wh lithium Aspire 5551 battery is reasonable, and it’s good to see that, in the intensive DVD test at least, this Aspire isn’t suffering from its processor’s extra core.

In fact, in the Productivity test this Aspire held up better than many similar laptops with older dual-core AMD processors, managing a full 3hrs and 21mins. However, raw horsepower is not the only benchmark where the 4820TG’s Core i5 wins the day, as battery life is also significantly better.

This brings us neatly onto our value considerations, where unfortunately the new Aspire 5551 doesn’t hold up too well unless you really need its CPU’s third core. If you can afford an extra money, the lighter Aspire TimelineX 4820TG is well worth the larger outlay, offering better build quality, battery life and general performance in applications and games. If you’re on a limited budget, the award-winning HP Pavilion dv6-2113sa is a better, with its lesser battery life offset by more connectivity and features (including ExpressCard, Firewire and Bluetooth), a larger hard drive and better performance. If Aspire 5551 battery life is a prime consideration, Dell offers an Inspiron with a Core i3 CPU and Radeon HD 5450 graphics with Bluetooth, while upping this will get you a Core i5-based dell Studio 15 with a Radeon HD 5470 and larger 500GB hard drive.

HP Folio 13 Ultrabook Review

Gesture Control – Sony E Series 14P Laptop Computer

Models of Sony in this release may not be the thinnest, is not the best performance, but these three E Series 14P notebook computers, there is always an attractive place. They are made of 14-inch 1,366 x 768 resolution screen, Intel Core i3 2550M processor, equipped with 4GB of memory, you can choose the AMD Radeon HD 7670M or Intel HD Graphics 3000 graphics card; on battery life, Sony promises there will be 7 hours of work time. Special selling point to the case of Gesture Control is the ability to support a similar Kinect as gestures: Unfortunately, currently only supports the Windows Media Player, IE9, PowerPoint, and PowerDVD. For the price, Sony still refuses to tell us, but before that, you can click to view Atlas, to see which color to match your taste.

Sony recently the creative constantly scroll tablet, dual-screen tablet launched, people can not help but praise, and the advancement of technology is really unlimited creativity tightly together. This time, Sony and the new action, the thinnest in this release models may not be on the market, nor the best performance of these three Sony Vaio e-Series the 14p notebook computer there is always attractive, most notably the selling point is a gesture is control gesture control, which allows you to slide the switch between the different pages, you can also adjust the music playback.

Several years ago, in fact, Sony have had a similar act of creativity, but is used in mobile phones, phone manipulation can control only with gestures, eye-popping. This design principle is preset in your phone a powerful image processing chip, high pixels (at least more than 5 million pixels) camera, the gestures of the user captured through a series of complex processing, and ultimately into a control The phone’s instruction.

Notebook Vaio e series 14p, is not a popular ultra-pole of this, but the gesture sensing control is also very unique, you can support page forward back and music playback control function. Unfortunately, its gesture sensing control only supports windows media player, ie9, powerpoint and powerdvd software.

Sony Vaio e-series 14p using 2550m processor, Intel Core i3, 4gb DDR3 memory, amd radeon hd7670m graphics with a resolution of 1366 × 768 14-inch screen, battery life up to 7 hours.

I am the camera handle I do not just decorative

I am the camera handle I do not just decorative

The reason why SLR cameras selling, the use of posture looks very professional accounted for part of the reason. Also will be selling the camera handle as you can instantly enhance the products of several times the mighty extent. Although we must admit that many users currently on the market to buy the camera handle to look better,but with decades-old product of the camera handle actually gone through a number of reform. For the vendors, after all, the introduction of a product not just for meaningless function to consider the actual use value is also very important.
 The camera battery grip is not really anything new has emerged early as a few decades ago the camera handle. But in that era SLR camera itself belongs to a relatively high-end products, most people will not buy a DSLR to take pictures. Called the slides on the handle in that era, the film is also pressed one to spend a money, most people who would buy them separately?So the vast majority of users to buy the camera handle only a grip and psychological satisfaction, as to practical use? There is no guarantee that does not drag drag.

With the continuous improvement of the camera electronics degree, corresponding to more and more integrated features,the camera built-in slides on is not what do difficult things, and fully integrated camera makes the meaning of the handle even more small, high-end camera still retain the installation of the handle to increase the film speed setting. Followed by the advent of the big wave of digital cameras, roll film is no longer needed, the expansion of the handle became First integration digital camera, and then reduced to a simple battery compartment. Until recently, the handle to accelerate once again came back to the camera handle can be said that the witness of the camera’s digital road.

will the long-term plug laptop power supply

Q: Ask the Expert, will the long-term plug laptop power supply (I believe this is the habit of most people, right?), The performance of the battery will not be affected? Oh, this may be a very food right? Hope reply. Thank you
A: a typical laptop battery charger design is less than 95% will be in charge, and because of the presence of natural wear and tear, so the loss for the battery, remove or not remove the basic are the same, so if removed as the habit may be, if you remove the battery wrapped in a fresh proposal membrane and placed in a dry cool place, and I remember a month or so and charge the battery at least once in order to avoid cell loss of activity. There are users that the use of alternating current, do not remove the battery charge and discharge will be repeated to reduce the battery life, in fact, the general life of the battery is fully charged according to the number of calculations, Li batteries are generally 300-400 times. Of course, you do not have to worry about the battery power on a single charge, even if only one point will be counted once, rechargeable battery generally only when the power to 80-90% of the total charge will be increased, otherwise the battery does it mean that 1 month to scrapped.
Q: Hello! Than Taiwan-made notebook brand strong? As Compower and Lenovo, Founder, ASUS, which brands work, the quality is better? I have only 9,000 or so, what price can buy a good laptop? ? ? 3KG in! The best long standby time point,Acer Aspire 5536 battery the screen a little brighter! Thank you!
A: 9 thousand or so of the domestic notebook, because more is provided by the public in Taiwan foundry model down products, workmanship or less the same compared to the Great Wall under the personally appreciate the work books, course books Asus workmanship is very good, Which final purchase specific products, but also on your personal preferences. You can choose Asus L4413C-D, Celeron M processors with this machine, ATI’s 9100IGP; in addition to Lenovo E255; Founder T5810D; Wall R3101D; ASUS Z8424C-D and so on.
Q: Expert: Hello, I have a IBM 535e laptop, but the sound is not what was put up! ! Please advise! !
A: First of all, make sure the driver you intend to install the correct version, even the same as those listed notebook models will be different in different individual hardware drivers. If the Device Manager an unknown device in the relevant sound card yellow exclamation mark appears, then in most cases is the driver is not installed correctly, of course, also possible that the hardware itself, and then how to install drive-way will not succeed, and this may repair the . Recommend using a USB interface, sound card, the price maintenance than the words of the chip, much cheaper.
Q: Hello! Thank you for your patience on the reader. My IBM A31P use the existing one and a half,dell Inspiron 1525 battery recently bought a digital camera and found that the imaging camera, color LCD than A31P brighter, more vivid. Taking into account the use of mobility fire GL7800 A31P display technology, I first thought that the camera’s LCD color cast. Photos from the past few days were lost in turn to the other two sony and IBM notebook and found that they display almost the same. Then compare Win XP desktop picture, A31P darker than the other book, more gray. – Then, A31P color cast it?
A: estimate your A31P LCD screen brightness low, or the graphics card driver is not installed with the result, if it is caused by the hardware, then, only to quickly detect what the blue.
Q: Hello: Now a lot of notebooks are the integrated graphics, and I want to buy a small notebook 12.1-inch LCD. But are most integrated graphics, SONY 505 price too high! Bad. What Intel855GME integrated graphics chipset can World of Warcraft it? When will all the special effects turned on smooth play? It can also play up to the present existence of relatively high demand market of what game? Thank you!
A Intel855GME run Warcraft 3 is no problem, if all properties open, 800X600 pixel resolution is also no problem, as under the effect of 1024X768 can not achieve the degree of fluency. As to the current market Intel855GME able to play games that demand high, the following gives you a set of measured data, whether this integrated graphics chip can run you want to play the game, you can know the results of comparison: the test items 1024×768 (32-bit color) and 800×600 (32-bit color) of the scores were: 3Dmark2001 1823 points 2430 points; 3Dmark2003 91 points 115 points. Test platform: Intel Pentium-M 1.4GHz, 256M DDR266, 30G, Intel 855GM + ICH4-M.
Q: Hello! Last summer, and I want to buy a laptop computer, now is your fancy Samsung X05, I ask how this configuration and quality. . . . Acer Aspire 5741 batteryI used the online chat, and lay a game (BNB), and some board games. . . . The memory capacity according to download such a thing to be enough? Can I analyze. . . . Thank you
A: Samsung X05 is a simplified version of X10, targeted at high-end business applications market. X05′s optical drive does not like the X10 uses the same ultra-thin optical drive, graphics card is not independent, but the price than the other X series would be better to accept some of the products. The current promotional price is 11,888 yuan, can be described as a very affordable, but also gifts. Configured to PM1.4G, 256M, 40G Combo preloaded with XP, configuration is very mainstream. 0.8mm ultra-thin 14-inch Samsung display fully inherited the excellent brand as the strengths of liquid crystal displays, ultra-thin LCD screen has a smooth flow of color display, with SIC intelligent inverter control technology, the situation in the use of battery-powered automatically adjust the LCD display. In the often interface also provides S / PDIF interface and S-Video port, rich on its digital and business expansion. It is only 2.0kg, 14-inch 12-inch big screen weight, but no graphics card a little bit less, and built-in battery capacity was also significantly smaller, Samsung’s policy is three years free warranty, and now sell gift options laptop bag, Optical Mouse. That meet your application requirements is no problem.
Q: I am a sophomore in school, summer intended to buy a NB, mainly watch movies, play games, and 3D graphics and programming, the price is like between 10,000 to 15,000, with a separate graphics card, the screen should relatively large, ask the experts what should I choose NB, and then Samsung would like to ask the service is good, in terms of relative ASUS? Thank you!
A: Samsung and Asus service is OK, than to teach it,Acer Aspire 5738Z battery personally think that some of Asus’s services more considerate. Recommend to your acer Aspire 2001WCLi, configuration, Aspire 2001WCLi with Intel SpeedStep technology with Pentium M processor 1.4GHz, 256M DDR RAM, 40GB hard drive, ATI MOBILITYTM RADEONTM 9200 (64MB dedicated graphics memory), 15.4 “TFT LCD screen ( 1280 × 800), inhaled COMBO drive, of course, built 56KFaxModem, 10/100M LAN, Intel PRO / Wireless 2100 wireless card. It is worth mentioning that, in addition to the two left and right channel speakers in addition, Aspire 2001WCLi the bottom of the still especially the installation of a subwoofer. expansion interfaces, Aspire 2001WLCi with three USB 2.0 interface, an infrared (FIR) port, an IEEE 1394 port, an external VGA port, 1 RJ-11 modem port, 1 headphone / speaker / line-out (line-out) jack, 1 Type II PC Card slot, a microphone / line input (line-in) jack, an RJ-45 Ethernet port, an S -video port, one parallel port. But the most special memory card or body in front of the reader, it can compatible with SD, MMC, MS, SM card.

should be added in distilled water or electrolyte

1, the level drops, it should be added in distilled water or electrolyte?
Distilled water level drops should be added, should not add electrolyte. Because the level has lowered due more to the end of evaporation and charging caused by electrolysis of water. If additional electrolyte, and it will increase the proportion of affected battery life. However, if the reduction is due to external tank surface cracks caused by the electrolyte leakage should be repaired and sewn together in series with a good electrolyte.
2, the electrolyte is on account of high surface should be more appropriate?
Electrolyte above the electrode surface should be 10-15 mm for good.compaq cq61 battery Too easy to spill liquid, corrosion around the parts. However, the upper plate is too low, easy to reveal, not only will reduce the battery capacity, and will soon cure the exposed plate. Plastic tank outside the battery slot on the high degree of identity with the electrolyte, usually liquid electrolyte should “max or U” marking flush.
3, the battery should do after freezing?
Frozen because the battery is generally:
(1) relatively low electrolyte battery factory. Electrolyte used in the cold regions reached the freezing point;
(2) Battery Over-discharge, the electrolyte has dropped more, but not timely charge;
(3) liquid electrolyte is too low, add distilled water, not to make the engine run up and down over time the proportion of the electrolyte is inconsistent, resulting in stratification.
General approach:
Frozen battery should be moved to let the room warm slowly melting; then provides charge current to 1 / 3 to the battery charge, continue to observe single-cell voltage and electrolyte temperature, electrolyte specific gravity after charging is completed should reach 1.28 g / cm3,Dell Vostro 1510 battery such as non-compliance, application specific gravity of 1.40 g/cm3 distilled water or sulfuric acid to adjust.
4, how to prevent plate curing?
(1) Do not let the half-discharge long-term storage pool thrown aside, To keep the battery charging status.
(2) electro-hydraulic liquid can not be too low, the surface must be 10-15 mm higher than the plate, add liquid should be added after the electricity.
(3) Do not let the battery from over discharge.
5, battery charging and not into power or charge can not afford cars?
(1) charging method does not, need special battery charger;
(2) a small charge current or charging time is short;
(3) charging clip is bad;
(4) battery plate sulfation occurs;
(5) bad wiring and battery clip, vehicle fault lines or other accessories;
(6) battery short circuit or open circuit fault;
6, pre sale, sale and maintenance of the vehicle battery
Sale, sale Charging:
Wrong way:
(1) can not start the vehicle battery to supplement the time of power;Dell Inspiron 1720 battery
(2) directly starting the vehicle, the natural rotation of neutral stop after ten minutes or hours;
The right approach:
(1) at least once a month to add the battery power;
(2) Remove the battery, charging requirements prescribed parameters with a dedicated charger charging.
Aftermarket battery maintenance:
(1) batteries must be kept clean.
(2) Do not fall into any foreign matter inside the battery.
(3) the single contact between the device and battery and wire connections must be completely reliable.
(4) Regular inspection and cleaning swab ventilation closures to prevent the battery vent plug.
(5) Always check electrolyte fluid levels, do not let the exposed surface plate and partition.
(6) additional fluid maintenance, battery charging must be terminated, the electrolyte to adjust to the normal density (1.28g/cm3).
(7) battery power is low,HP G71 battery non-forced from the car.
(8) manual electrolyte temperature should not exceed the specified value, usually 45 ℃.
(9) in accordance with the instructions, a balanced supplement regularly (over charging).
(10) If the battery is long-term hold, in order to avoid excessive self-discharge and severe sulfate should be added monthly electricity.
(11) battery use, the charge involved in the process of fire is strictly prohibited.
(12) on a regular basis at the smear of butter in the terminal.
(13) is strictly prohibited in the vehicle to adjust the rotation or twist cable clip, to prevent sparks and explode.

RAM chips and SRAM chips

RAM chips:

Preceding the introduction of relatively simple and abstract. Here we will work together with the actual RAM chips are introduced. When it comes to this issue, we would involve a more important technology: encapsulation. You should have heard such as 30 lines 72 lines of the SIMMS, SIMMS and DIMMS of 168 lines or the RIMMs which one or several terms. If you want to explain the difference between these terms, you should be aware of the HP Compaq Business Notebook NX6105 Battery packaging technology of the RAM.

SRAM chip:

Early SRAM chips using 20 lines of dual in-line (DIP: Dual Inline Package) packaging technology, the reason why they have so many pins, because each address signal, they must: a signal line; a data input lines and a data output line part of the Line of Control (Write Enable Chip Select) to; lines and power lines

A0-A13 address input signal pins, CS is the chip select pin. In a practical system, it certainly has a lot of Nikon Battery Grip SRAM chips, and so need to choose whether Since an SRAM chip, write or read data. WE is the write enable pin (in the above table, I did not write the above line in the CS WE, indicating that the active-low or logic 0): When the SRAM address, it needs to know what what is written or read, the WE is to tell the SRAM to write data. Vcc is the supply pins. Din is a data input pin. Dout is the data output pin. GND is the ground pin

Output:

Enable (OE): Yes Cell Phone Jammer SRAM chip, this pin, but the above figure. Pin with the WE pin function is relative, it is to allow the SRAM to know to read rather than write operations. 1bit data read from the Dout pin requires the following steps:
SRAM read operation: 1) by the address bus to read the bit address sent to the corresponding read address pins (the / WE pin should not activated, so the SRAM it should not perform a write operation). 2) activation / CS to select the SRAM chip. 3) activation of the / OE pin SRAM know the read operation. After the third step, to read data from the DOUT pin transmission to the data bus. How the process is very simple? Similarly, write 1bit data is very simple. SRAM write operations: 1) to write the address bus to determine the location of the information (to determine the / OE pin is not activated). 2) via the data bus to be written to the data transmission to the Dout pin. 3) activation / CS pin to select the SRAM chip. 4) activation of the / WE pin notice SRAM know to be dedicated to write operations.

After the four steps above, the need to write the HP HSTNN-IB0X Battery data has been put in place to write.

DRAM chips

Now we know the steps to read and write operations in a simple SRAM chip, and then we look at the work of the ordinary DRAM chips. DRAM compared to SRAM is more complicated, because the need for the information stored in the process of DRAM memory data refresh, and this is the biggest difference between them. Let us look at the role of the pins of the DRAM chips.

The earliest, simplest and most importantly, a DRAM chip released by Intel in 1979, 2188, the Apple a1175 battery chip is the 16Kx1 the DRAM 18-wire DIP package. 16K x 1 “part of the mean tells us that the chip can store up to 16 384 bit data in the same period can to 1bit read or write operation. (Sorry can not find the physical picture of the chip, had a simple drawing of a diagram).

The obvious difference between DRAM and SRAM. First of all, you will see the address pins from 14 to 7, then the Fengyun 16K DRAM how to complete the work with 16K of SRAM? The answer is simple, the DRAM through the DRAM interface address is divided into two, and then use two consecutive clock cycles transmission address data. Achieved using half pins to achieve the same functionality with SGRAM purpose, a technique known as multiplexing (multiplexing).

So why reduce the address pins? What are the benefits to do so? As we have introduced the storage the 1bit the NIKON Camera battery data SRAM requires 4-6 transistors DRAM only need a transistor, then such the SRAM volume of the same capacity than DRAM. At least four times. This means that you do not have enough room to place the same number of pins (because the pin has not decreased by 4 times). Of course, in order to install the same number of pins, chip volume increased, but this increase in production cost and power consumption of the chip, so is also necessary to reduce the number of pins, addressing technology for large-capacity DRAM chips, is essential.

Of course, Canon BG-E8 Battery Grip multiple addressing technology also makes the process of reading and writing more complex, so that when the design is not just a more complex DRAM chip DRAM interface is also more complex.

In the illustration above, you can see more for SRAM DRAM structure of two parts: / RAS (Row Address
Of Strobe: row address pulse strobe) pin controls the row address latch circuit (Row Address the Latch) and / CAS (Column Address of Strobe: column address pulse strobe) pin controls the column address latch circuit (Column Address the Latch ). DRAM read process: 1) through the address bus address line transmission to the address pins. 2) / RAS pin is activated, so that the row address transmitted sent to the row address latch circuit. 3) the row address decoder according to the received data to select the appropriate line.

4) / the WE pin is determined not to be activated, so the DRAM knows that it does not write to. 5) the column address to the address pins via the address bus transfer. 6) / CAS pin is activated, so the column address is transferred sent to the row address latch circuit. 7) / CAS pin also has the function of the / OE pin, so this time the Dout pin aware of the need to export data.

/ the RAS and / CAS are not activated, so that you can for the next cycle of Solar Charger for Laptop data manipulation. In fact, the DRAM write and read is essentially the same, so if you really understand the above process will be able to know the writing process, so here I will not go into details.

Initial purchase of laptops for each consumer will experience two difficult problems

Initial purchase of laptops for each consumer will experience two difficult problems, one is how to choose, and the other is how to choose a good test machine, while the focus of this article is to teach you how to smoothly through the testing machine this link .
In order to avoid the development of machines to buy profiteers, pathogenesis, testing machine of this aspect is particularly important, although the three bags of pledges return 15 days replacement 3 days, even to enjoy the same Warranty Services will bring their own a lot of unnecessary trouble, not to mention wait until after a period of three bags found the problem.
As notebook computers in the computer market to buy time is often more limited, so we can not on a laptop computer to conduct a comprehensive test, I personally think that when buying laptops should focus on the appearance of the machine, serial number, screen, drive, keyboard, ports, etc. to check, while others can be based on the actual situation.
First, optimistic about the appearance of the re-start
If you buy is licensed in most cases, the machine seals the box should be intact,Nikon MB-D10 battery grip if a proposed business has opened a sealed box while the machine may be used for display or have been picked off on a buyer machine, you have every reason to request exchange.
General box in each laptop will have a detailed packing list, then you can control the documents and information take a look at all the parts are complete, such as CD-ROM, a total of a few, a total of several instructions, What are the accessories, in short, like a lot to do. In addition to look at the bottom of the machine is affixed with genuine Microsoft operating system’s serial number sticker, or a random valuable genuine operating systems becomes waste.
Then please do not power on, you should carefully check the machine out the appearance of the machine,Dell Inspiron 6000 Adapter are there plans, knock, touched the mark, especially in the corners and bottom of the machine rubber pads for wear; fixed screws have been twisted flowers; Also note that the surface of the machine there is an obvious use of signs, such as fingerprints, grease, etc., because the surface coating as many features of the machine once a trace is difficult to clean. You can then open the screen repeatedly opening and closing times to see if there was loose, and look carefully to see if there are glossy keyboard, especially the letter keys and the spacebar. Finally, check the PC card slot replacement baffle plate and the interface for any damage or loss, the appearance of the test that is down to this end.
Second, carefully check the serial number
Before the formal start of the serial number we have to check boxes, and the BIOS information in the bottom of the machine serial number are consistent with the formal adoption be considered. How to enter the BIOS settings as different models may be, some models such as Toshiba, does not boot into BIOS functions check only the bottom of the box and the machine serial number.
Storm coming! A sultry summer, suddenly, the sky darkened, thunder, lightning glare …… this time you really thought about, get out your camera, captured this memorable moment?
You might think the Lightning captured the sharp need for super-quick response capability. No, you’re wrong. You just need to stand at the right time right place on the line. If you take a few minutes watching the sky, you will find that lightning is in the air moving, but it intermittently with missing trends. You can not accurately calculate a bunch of lightning appears under the time and place, but you can predict in a few minutes to a regional lightning may occur, in particular, is always accompanied by thunder and lightning. This is the key. If you set the camera has a long shutter speed, you will record the ongoing flow of lightning. Sharp lightning may be only a few seconds there, but by a few minutes of the shooting,Dell Inspiron 1300 Adapter you will always have a surprising grasp and lightning effects.
First, the tools you should be prepared to
You need a camera with long exposure settings. Pretty good rate of 30 seconds. But if another shorter, you get the odd chance of lightning would be reduced. You can manually set the shutter speed, but if the camera has an automatic setting also, you have to turn off the automatic flash.
You also need a tripod to keep the camera stable. Recommend the use of a wide range of values of the camera lens, so that the air you captured a wider range of areas, there will be more opportunities to photograph lightning. Ideally taken in the evening. Of course, if lightning occurs during the day, do not miss. Only during the day, you do not want to make the sky is overexposed, and want a long shutter speed, so the opportunity to shoot lightning will be very limited.
Second, to begin shooting
Then we put the camera tripod, aim it appears you think the lightning area. The camera is set to the smallest possible aperture: f/16 or f/22. If your camera is fully automatic, there is no over-exposure control, then you only need to make sure the flash is closed. We can also a detailed description of the camera, to check the ability of its long exposure. Raytheon equipment like a good time, often give us direction for the next bunch of lightning occurred. Between several minutes of thunder, lightning will always be there. After the current burst of thunder, lightning will come much faster.Dell Inspiron 1720 Adapter It flashed faster. This is a good indicator: Lightning How far away from us. In general, the 15-second interval will imply Lightning 3 miles away from us. This can help us decide what press the shutter. Here, control the shutter using a cable would be better, so will not cause shaking.
Hold down the shutter, keep your fingers do not move, until the lightning occurred in the target area. If your camera has a separate viewfinder, you will be able to see whether lightning is photographed. Here, the use of digital cameras have an advantage is that you can preview the captured images, if not shoot, then delete it and re-shoot. But if it is used SLR cameras, it does not. Because it is progressive lenses, you can only pray that lightning was captured.
If your camera has a B setting, you can put the shutter open. Cover the lens with a card. When you think that lightning will occur, the card is removed, photographed and then can put it back. Finally repeat, time to grasp is the most critical. You need a total exposure time of 30 seconds, so you may be in a photograph in the film several times lightning. I have photographed over two beams of lightning. We can see from the figure.
Third, where the shooting lightning
There is also a most important issue is security. Because we are shooting outdoors lightning is very dangerous. A storm on the one hand, on the other hand may face lightning attacks. Therefore, we are likely to wonder whether the shot at home safely. RIGHT! From a scientific point of view, shooting lightning under a tree is more dangerous. Therefore, we the best in the house, car or large building shooting. If it is within the car, you should open the windows. Indoors, you should stay away from windows, water, electrical appliances, avoid using the telephone. Try to put the camera placed near the window,Dell Inspiron 1750 Adapter use the cable remote control camera shutter. If you can see the lightning through the open window area there, so will not appear reflective glass or other defects: such as lower quality, the camera focusing problems and so on. If you are shooting through a closed window, then the light bulb to turn off the house, if needed, use the flashlight to light. At the same time adjusting the camera’s auto focus to manal focus or infinity mode (if any).
We can also select a window, can clearly see the lighting of the mobile trend. Of course, we can do in a car. This is even more dangerous point. Particular care.
If you think outside of shooting, just like this picture I shot the same (this can be very stupid, but adventurous and gone for the arts, but also very worthwhile.) We can not rain before the storm is about to start, photographed for the first bunch of lightning. If you are shooting in the rain, we must pay attention to protect the camera. Therefore, it is best to use a special kit, such as plastic wrap with a camera. Always remember, stay away from trees!

Maintenance of the computer external device

Mouse and keyboard failure

Mouse failure

(1) The system can not find the mouse

Analysis and diagnosis:

(1) Check the mouse and the host interface contacts are good. Mouse interface is carefully plugged in, restart the system.
(2) mouse in the line connection is bad, this failure is often seen in the mouse inside the wire with the circuit board connections. The solution is to open the mouse, use the electric iron solder joint welding can.
(3) There is a serial port may be burned, but this happens rarely, if the serial was burned out and had to replace a board.
(4) mouse cable wire disconnected. Use NP-FH100 Battery electric iron welding.

(2) abnormal mouse cursor or does not move

May dirt interrupt conflict or mouse. Interrupt resource problems can be solved by “6-1 Day” method; otherwise right mouse descaling processing.

(3) mouse button failures

Are mechanical failure. For the mouse button does not bounce, may be a fracture caused by the button below the contact switch in the bowl-shaped contact pads. Three-button mouse, you can remove the middle of a weld to meet urgent needs replaced, or can also be transplanted from a discarded mouse; the ability to click the switch bounce down, you can open the mouse, glue a mouse button in the following moderate thickness of the plastic sheet, and then install the mouse to normal use; I click the switch has been damaged, can be set to “right-handed” in the control panel mouse settings window (if you do not often use the right mouse button, then). However, you will feel when they are in operation very smoothly, it is best for a mouse.

Keyboard failure

Fault phenomenon: Sony laptop battery Keyboard Power On Self Test by typing A, S, D,, F, and V, I, O, P these two sets of keys not playing characters.

Analysis and processing: open the keyboard to see the transparent plastic circuit board, and many contacts. First check whether the key contact pressure together, everything is normal. Then a multimeter the contacts are pressed together can conduct electricity, everything is normal. Then check whether conductivity point of contact and the circuit board, or normal.

Carefully checked and found a circuit metal film out as part of the EOS 550D Battery Grip circuit is connected, look a little sparse. , Measured with a multimeter, the resistance is very large. May be due to the resistance of large electrical signals can not pass, but also happens to be that two sets of letter keys of the public line, so the key is the group not playing characters.

To plastic circuit connection is not a simple matter. Not electric iron welding, a welding, plastic will burn off. The first wire at both ends of the copper stripping out the two holes (be sure to avoid the bad section), available on both sides of the circuit resistance is also a small bar, wire stripping out copper wire to go through the hole, as tie circuit, the other end did the same. With a multimeter volume through! Fastened shell will also cushion some paper to prevent loosening. On machine one, everything is normal.

Inkjet printer common failure

This section introduced the EPSON 1500K printer, for example the treatment of the common faults of the inkjet printer.

Data and is out of paper light is flashing

A feed printer settings inconsistent with your actual feed method, the alignment of the.
(2) When loading paper, the printer does not accept. This problem lies in the switch of the check paper, due to prolonged use, the sensitivity of the check paper drop. Remove the back of the printer’s manual feed slot, it is easy to see the location of the check paper, it connected with the motherboard is a set of yellow lines, to remove it (using tweezers) with a multimeter testing, will be found check The paper switch is not flexible or disconnected. Rinse with alcohol or replaced, the problem can be solved.

Portable Solar Laptop Charger Data and the Pause light is flashing, or print the first hit in the head about

Analysis and treatment:

(1) This problem is primarily due to the prolonged use of a lot of debris (dust) between the print head and the guide rod, causing too much resistance. Turn off the printer, the guide rod clean with cotton dipped in absolute alcohol, coupled with the transformer oil or sewing machine oil, pull a few times about hand, can solve the problem.
(2) boot, the print head can not correctly positioning the SONY Camera Battery printer crash phenomenon. Can turn the printer off after a few seconds to boot, you can print normally.

All the indicator light flashes

This phenomenon, many users thought it was a printer to be a big problem, or that the quality of this printer. In fact, the contrary, this is it has the advantage, because the motherboard on the EPSON 1500K to a count of the chip is designed to calculate the number of paper, when the number of printed pages to achieve the specified number of print, the printer requires user waste cleaning, ink cartridges and chip count is cleared; or directly on the chip count is cleared (recommended not using).

Specific methods are as follows:

(1) print organs, remove the black ink cartridges;
(2) the scroll knob and remove the cutter;
Remove the control panel (panel in front of a clamp);
4 Remove the three screws around the (control panel), with a Battery Grip for Canon BG-E3 flat screwdriver to the printer the following clips Bankai; and then remove the lid, clamp the waste ink box of bubble wipe to remove water rinse and dry ;
(5) The above work is completed, will restore the printer, power. At this point you will see the failure phenomenon with the original, because you have not the counter is cleared. Press the switch – line feed / form feed – feed / back paper – micro adjustment of the right button, and then boot. When you hear the crisp voice instructions.

Print out the words distorted

The direct use of the software that comes with the printer calibration, and specific methods are as follows:

(1) hit the pause button and boot;
Load A4 paper to print The printer will print out two state of the current printer’s proofs (First To illustrate the method, the second calibration pattern Pattern 1). The two-page printed, the printer status lights for power. The observed calibration pattern is in the aligned position NO.1 to NO.25, from This NO.x start the calibration, when a NO.x vertical bar is not on time, and press the switch button until the indicator light to indicate the appropriate Pattern number. Print, print from your chosen NO.x start the calibration press the pause button, but the printer still print from the first root vertical bar. The printer will continuously print 7 Note: do not close the printer is printing. When you determine the final choice (page 7), turning off the printer power. Online and then print, if the word is still distorted, repeat the above steps until the correct date.

Also note that, before turning off the Aspire 5720 battery printer, make sure that the Pause light, because this is the printer a sign that the end of the mission, or that the non-normal shutdown, the next boot, the printer will clean the print head again, this will waste a lot of ink .

HP Deskjet 695C inkjet printer failure example

Fault phenomenon: the printer uses the past year, work has been normal. Third place can be when you print, always hit the paper, the print head will not move, reply to the indicator and power indicator light flashes alternately, Windows prompt “print head can not move the printer to jam.”

Analysis and Processing: Follow the prompts to open the printer cover, remove the paper, did not find a scrap of paper. Re-print, the fault remains. Began to suspect that there is a problem with the printer software, so re-install the printer software again, you can fault no excluded. When re-open the top cover of the printer, remove the paper and found that the printer used a fixed print head, so that the print head moves back and forth axis, has lost its past light, black, hand touch, friction. As the dust so that oil thickens, so that the shaft friction increase the printer’s print head movement difficult, so the printer report a paper jam.

Thus, with a cloth (note the cloth must not hair loss) and the shaft clean, preferably polished bright as ever, and then BlackBox 500S Receiver wipe the lubricant in the above, but do not impeccably too. After the above processing, the printer will not jam.

Final recommendations: the periodic inspection, regular activities in the inkjet printer parts to be cleaned regularly.
