Battery
The system battery maintains system configuration, date, and time information in a special section of memory when you turn off the system. The operating life
of the battery ranges from 2 to 5 years, depending on how you use the system (for example, if you keep the system on most of the time, the battery gets little
use and thus lasts longer). You may need to replace the battery if an incorrect time or date is displayed during the boot routine along with the following or
similar message:
Time-of-day not set -- please run SETUP program
Strike the F1 key to continue, F2 to run the setup utility
or

Strike the F1 key to continue, F2 to run the setup utility
or

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.
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 not caused by a defective battery.
WARNING:
Before you perform this procedure, you must turn off the system and disconnect it from its power sources. For more information, see the
safety precautions in your system information document.
WARNING:
There is a danger of a new battery exploding if it is incorrectly installed. Replace the battery only with the same or equivalent type
recommended by the manufacturer. Discard used batteries according to the manufacturer’s instructions.
CAUTION:
Read the safety instructions in your System Information document.
