Troubleshooting the System Battery

Problem

l
System Setup program loses system configuration information
l
System date and time do not stay current
l
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.
You can operate the system without a battery; however, the system configuration information maintained by the battery in NVRAM is erased each time you
remove power from the system. Therefore, you must re-enter the system configuration information and reset the options each time the system boots until you
replace the battery.
Action
1. Re-enter the time and date through the System Setup program (see "Using the System Setup Program" in the User's Guide for instructions).
2. Turn off and disconnect the system from the electrical outlet for a few hours.
3. Reconnect the system to the electrical outlet and turn the system on again.
4. Enter the System Setup program.
If the date and time are not correct in the System Setup program, replace the battery (see
If the problem is not resolved by replacing the battery, see
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 (weeks or months), the NVRAM may lose its system configuration information. This situation is
not caused by a defective battery.
