Installing System Board Options
8-17
To determine if the battery needs replacing, reenter the time and date through the
System Setup program. Turn off the system for a few hours, and then turn it on again.
Enter the System Setup program. If the date and time are not correct in the System
Setup program, replace the battery.
NOTES: 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 pro-
gram, the problem may be caused by software rather than by a defective battery.
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 not caused by a defec-
tive battery.
The system can be operated without a battery; however, the system configuration
information maintained by the battery in NVRAM is erased each time the computer is
turned off. Therefore, the system configuration information must be reentered and
the options reset
each time the system boots
until the battery is replaced.
The battery is a 3.0-volt (V), coin-cell CR2032-type battery. To remove the battery, fol-
low these steps.
1.
Enter the System Setup program and, if possible, make a printed copy of the Sys-
tem Setup screens.
See Chapter 4, “Using the System Setup Program,” in the
User’s Guide
for

tem from the electrical outlet.
