This section contains information on the Notebook’s power system, 
including the AC Adapter, the battery system, recharging the 
battery, and tips for conserving battery power.

Before using the computer on battery power for the first time, 
check the battery status icon on the Windows Toolbar to make 
sure the battery is fully charged. 
See Battery Status later in this section for a description and 
explanation of the Windows Battery icon. Charging the battery 
takes about 3 hours to charge when the system is in off state. If 
possible, always charge the battery completely. 
If you use the battery so frequently that it exceed more than 20 times 
by fully discharging/charging in a single month alone, we 
recommend you to perform the “Battery Calibration” process every 3 
months to maintain the battery life. Please refer to the topic on 
“Battery Calibration” describing how to calibrate your system 
battery discussed on the latter part of this chapter. 
 
If you discover the battery life is getting shorter, please perform the 
“Battery Calibration” process immediately.

IC within the battery pack should be calibrated in order to get 
accurate reporting of remaining battery life status.
