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.
You can operate the system without a battery; however, the system configuration
information maintained by the battery in NVRAM is erased each time you shut down
the computer. Therefore, you must reenter the system configuration information and
reset the options each time the system boots until you replace the battery.
The battery is a 3.0-volt (V), coin-cell CR2032-type battery. To remove the battery, per-
form the following steps.
