Connect the AC adapter to the computer.
Insert the battery pack.
The computer automatically charges the battery (the battery indicator light flashes in a double blink pattern as the battery charges). When the battery is 85% full, the battery indicator light turns off. This process takes approximately one and one half hours. To charge the battery completely, continue charging for an additional hour.
The 
battery indicator light on the front of the computer indicates the status of the battery pack.

Keep the battery pack in the computer while it is directly connected to AC power. The battery pack continues to charge while you are using the computer.
If your battery level falls to less than 10 percent, you should either attach the AC adapter to recharge the battery or shut down your computer and insert a fully charged battery.
You can extend battery life by changing the power management modes in the PowerPanel utility. See “Using Power Saving Modes” on page 34.
