Power Management — Power Management 

The first time you use a battery, you should calibrate it. The calibration process empties and charges 
the battery one time. 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? 

 

Would you to do battery auto-learning?  

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 again 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 will hold less than 100% 

of the potential charge.
