Troubleshooting The NVRAM Backup Battery
CAUTION: Many repairs may only be done by a certified service technician. You should only perform
troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or
telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your
warranty. Read and follow the safety instructions that came with the product.
The battery maintains the server module configuration, date, and time information in the NVRAM when the server
module is turned off. You may need to replace the battery if an incorrect time or date is displayed during the boot
routine.
You can operate the server module without a battery; however, the server module configuration information maintained
by the battery in NVRAM is erased each time you remove power from the server module. Therefore, you must re-enter
the system configuration information and reset the options each time the server module boots until you replace the
battery.
1. Re-enter the time and date through the System Setup.
2. Remove the server module from the enclosure for at least one hour.
3. Install the server module in the enclosure.
4. Enter the System Setup.
If the date and time are not correct in the System Setup, replace the battery. If the problem is not resolved by
replacing the battery, see
Getting Help .
NOTE: If the server module 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.
NOTE: Some software may cause the server module’s time to speed up or slow down. If the server module
operates normally except for the time maintained by the System Setup, the problem may be caused by a
software rather than by a defective battery.
