whether there is any need to calibrate the battery, how to calibrate the battery? The answer is yes, because the use and rechargeable batteries in the factors of instability will cause the battery capacity decline, but this decline is not caused because of aging, so proper calibration can make this part of the loss of the capacity of recovery . Therefore periodic battery calibration is very necessary thing, such as a January-February.

Such as Compaq and IBM laptop itself on the BIOS or Power Management program provides a battery calibration function, so the use of these two brands can be reproduced as Friend prompts. For those who did not provide this feature the user can follow the brand I have the following steps:

1. The screen saver is set to "None"
2. In the Windows Power Management power scheme will be set to "always open" and will be following the closure of all equipment related to the menu set to "never"
3. In the alert tab will be "insufficient power warning" is set to 10 percent, operation is set to "refrain from any action"; will be "a serious shortage of electricity alarm" is set to 3%, to operate as a "standby"
4. The screen brightness to the highest
5. To confirm the closure of all of the window, and save all the data before the job
6. To confirm battery after more than 80%, unplug the power and all external equipment, at this time if the screen automatically reduces brightness, then I would be grateful if it hit the brightest

OK, you can go to bed, and discharge after the end of the notebook will automatically shut down after the power plug so that the notebook charging, attention must be completely filled, such as after the boot, and then restored to power the program before the calibration settings.

The aim is to enable the continued low current battery discharge, which discharge state in our daily use are impossible to achieve, because the normal state is inevitable that we will conduct various kinds of make up and down changes in current operations.

IBM, SONY such a machine can detect the capacity of the battery before and after the change, other machines can download a program called the batterymon to see, you will find, with a capacity of 1.1 points in the restoration, but here to remind you that if you have the battery because excessive use and aging, and that this temporary solution is to use do not have a point.

Some relative battery:

This method is also recommended that the new machines just get a friend to use, the general Li battery before being put into use in accordance with this method the best for 2-3 times, so as to enable the greatest possible input of batteries for optimal performance status.
