does not operate with a
fully charged battery.
The battery does not
charge.

The surge protector in the battery might be active. Turn off the
computer for one minute to reset the protector; then turn on
the computer again.
Replace the battery.
Hard Drive
In the Boot menu in AMI Setup Utility, make sure that the hard
disk drive is included in the Boot Sequence.
Other Problems

button for 4 seconds or more. If the computer still does not
respond, remove the AC adapter and the battery.
Your computer may lock if it enters sleep mode during a
