Charging the battery pack
To charge the battery pack, proceed as follows:
1
Connect the AC adapter to the computer.
2
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 two and a half hours if the notebook is on. To charge the battery
completely, continue charging for an additional hour.
When the battery is running out of power, both the battery and power indicators blink.
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 the battery level falls to below 10%, 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.
The battery pack supplied with your computer is a lithium ion battery and can be recharged any time. Charging a partially discharged battery does
not affect battery life.
The battery indicator light is on while you use the battery pack as a power source. When the battery life is nearly depleted, the battery indicator starts
flashing.
