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 percent 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 two to
four hours. The time varies based on your system configuration. See
“Displaying Detailed Battery Information” on page 71 for information on
