Battery Calibration

The first time you use a battery, you should calibrate it. The calibration process empties and charges the battery once. This allows the Windows battery gauge to accurately monitor battery status. To calibrate a battery, follow these steps:

1.Plug in the AC adapter.

2.Restart the computer and when the startup screen appears, press Del key to enter the BIOS Setup Utility.

3.In the BIOS Setup Utility, select Power Management Setup , choose Battery Auto Calibration, then press <Fn><PgDn>.

Please make sure that AC adapter & Battery are present?

Do you wish to do the battery auto-learning?

Yes.

No. (System Reboot)

4.Press <Y> at the above Battery Auto Calibration dialog to begin the battery calibration. Please press [Space Bar] to select option, and [Enter] to continue.

Battery Calibration will take from 8 to 10 hours, depending on how much power the battery may already contain.

Note: For optimum performance, we recommend calibrating the battery every three months. Each time you charge and discharge a battery, it loses a tiny part of its storage capacity, so that, over time, it will store less than its potential charge. Similarly, if you do not use the battery for a few days, it will slowly self-discharge, and when it is recharged, it may hold less than 100% of the potential charge.
