Laptop battery correction(2)

Laptop life become shorter because many charge and discharge process, the battery in the laptop BIOS system battery power a miscarriage of justice, this case, we can let the battery calibration method notebook power remaining to give full play . Introduce the following two methods to calibrate HP ProBook 4520s Battery.
Standard calibration method: using notebook bios Sony VGP-BPS8 Battery calibration

Many brands of notebook computers are integrated in its BIOS battery calibration procedures, the general statement in English is called “Battery Calibration” battery proofreading. Direct access to books BIOS HP-Compaq nw8240 Battery calibration operation can be done.

1, boot, after the start-up screen appears, press F2 to enter BIOS menu; through the left and right arrow keys to select the Power menu.

Enter the Power menu, you can see “Start Dell Precision M65 Battery Calibration” option, select it and press the Enter key to perform.

3, when the screen turns blue, and English prompted to plug the notebook power adapter to charge the Dell Latitude E5520 Battery. And so the battery is fully charged, the screen prompts the user to disconnect the power adapter. After the notebook continue to discharge the battery until the battery runs out.

4, this process will take some time, and then connect the power adapter to charge the battery until the battery runs out after the automatic shutdown, but do not boot. Charging is complete (charging indicator goes off), and the HP ProBook 4420s Battery calibration process is completed.

Manual correction method: let the laptop boot natural discharge

Some notebook to find how to find the battery calibration option in the BIOS. Is this Dell inspiron 8200 Battery calibration can not hold it? Manually set the books to work properly discharge until the automatic shutdown.

The principle of the natural discharge

On the surface, the battery calibration process is to charge and discharge the battery, but it is not like we imagine that activate the battery, because Toshiba PA3536U-1BRS Battery now are lithium batteries, there is no activation problems. The charge and discharge of the real purpose is to allow the computer to re-recognize the capacity of the battery. So to try to call on clean, so that books work in smaller power correction effect so we go.

, Notebook operating system (Windows XP for example) into the “Power Options”. Select the power scheme to “always open” and “Turn off monitor” and “Turn off hard disks” is set to the shortest possible time, and the system standby to be set to “never”.

2, in the “Power Options” in the “alert”, cancel all alert options, the purpose is to let the HP-Compaq nc8430 Battery is completely depleted until the shutdown.

3, after setting, close all applications, turn off the WIFI, unplug the power adapter, battery-powered. Do not do anything until the Asus c41-ux50 Battery runs out after the automatic shutdown. After discharge, even on the power adapter, the battery is full, then completed a battery calibration.

If the correction to the Dell XPS M1730 battery, the battery life is not obvious, it may be the battery itself due to aging, if the laptop battery life is normal, I do not recommend using the battery calibration.
