May be you are now have a laptop or more, but how many laptop battery tips are you have? How to take care laptop battery, if you use a laptop ac adapter to connect laptop for long time?

1. Laptop Battery Scheme

Most laptops has the function of automatic frequency reduction, this function’s advantage is prolong the laptop battery using time. The users of Celeron CPU based laptop might puzzled, their laptops don not have this function, So is it have no way to save power? The CPU is just one part of the save power union, actually, The power consuming parts are: LCD > CPU(full speed) > graphics card > WLAN card > CPU fan. That to say, except the CPU, we can also maximumly reducing power consumption from the other parts.

If you are a Windows xp user, you can find the laptop battery power management options in the Windows XP control panel. Choosing “power using scheme”, then setting LCD screen in idle 10 minutes to close, and set the disk above 15 minutes. Because the momentary boot disk requires a certain power, and frequently start or stop will damage the disk. Of course you can close the screen manually, most laptop can do this by FN function key and F3 key.

The above are the way to save laptop battery power through Setting LCD and disk closing time. if you want to further saving battery power, you need to adjust the operation of the system state, But this is not a Windows XP operate system can done. For example, The Thinkpad laptop have a self-contained battery management software. Lenovo Thinkpad Battery. General laptop screen will provide 8 level brightness adjusting, although the brightest state can get the best visual effect, but it was very, very power consumption. So, when edit the document or some other common application, the screen brightness should adjusted to the 7 level or lower 6 level appropriate. Meanwhile, the CPU can also set up to best battery performance, CPU fan operation state set up to “equilibrium” more laptop battery power saving. Be aware of some laptop have no battery management software (because they have no built-in power management chips), but we also can use common battery monitoring software to manage the laptop battery. BatteryMon was a good common battery monitoring software.

For example, we test thinkpad T61 battery. When thinkpad t61 run at full speed played on DVD, the laptop battery life is only 2 hours and 37 minutes. If the t61 laptop battery optimized solutions use, its life can reach to about 3 hours and 17 minutes. we can see the ascension was very obvious. These are setting up laptop screen brightness, laptop CPU speed, laptop fan speed to save battery power. Replacement lenovo thinpad ac adapter.

So, you need to change the config of the charging set. In addition, it’s useful to turn off your laptop when you charging it, that’s can prolong your laptop battery life.

After depth discharge, Then use a battery charger or adapter to keep a depth charging, the charging time need to over 8 hours, but not more than 12 hours, Keeping this way, your laptop lithium battery will restore some power electric.
