defective battery.

the System Setup Program and Boot Manager" on page 25.

Turn off the system and disconnect it from the electrical outlet for at least

Reconnect the system to the electrical outlet and turn on the system.

Enter the System Setup program.
If the date and time are not correct in the System Setup program, replace

If the problem is not resolved by replacing the battery, see "Getting Help"

system seems to operate normally except for the time kept in the System Setup
program, the problem may be caused by software rather than by a defective
battery.
