Troubleshooting Your System

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

1 Re-enter the time and date through the System Setup program. See "Using

the System Setup Program" on page 45.

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.

If the date and time are not correct in the System Setup program, replace
the battery. See "System Battery" on page 117.

If the problem is not resolved by replacing the battery, see "Getting Help"
on page 181.

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.
