To charge the battery pack
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 hours. To charge the battery completely, continue
charging for an additional hour.
A fully charged battery pack supplies power for approximately three to
five and a half hours. The time varies based on your system
configuration. See “Displaying Detailed Battery Information” on page 69
for information on checking the battery life.
