Troubleshooting the System Battery
Problem
System message indicates a problem with the battery.
System Setup program loses system configuration information.
System date and time do not remain current.
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.
Action

Re-enter the time and date through the System Setup program. See "Using
the System Setup Program" on page 31.
2
Turn off the system and disconnect it from the electrical outlet for at least
one hour.
3
Reconnect the system to the electrical outlet and turn on the system.
4
Enter the System Setup program. See "Using the System Setup Program"
on page 31.
If the date and time are not correct in the System Setup program, replace
the battery. See "System Battery" on page 88.
If the problem is not resolved by replacing the battery,
see
"Getting Help"
on page 137
.
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.
