Troubleshooting the System Battery

NOTE:
If the system is turned off for long periods of time (for weeks or months),
the NVRAM may lose its system configuration information. This situation is caused
by a defective battery.
1 Re-enter the time and date through the System Setup program. See
"Entering the System Setup Program" on page 58.
2 Turn off the system, including any attached peripherals, and disconnect
the system from its electrical outlet for at least one hour.
3 Reconnect the system to its electrical outlet and turn the system on,
including any attached peripherals.
4 Enter the System Setup program.
If the date and time are not correct in the System Setup program,
replace the battery. See "Replacing the System Battery" on page 133.
NOTE:
Some software may cause the system time to speed up or slow down. If the
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.
If the problem is not resolved by replacing the battery, see "Getting Help"
on page 181.
