Troubleshooting the NVRAM backup battery
Prerequisites
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 are shipped with your product.
The battery maintains the blade configuration, date, and time information in the NVRAM when the blade 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 blade without a battery; however, the blade configuration information maintained by the battery in NVRAM
is erased each time you remove power from the blade. Therefore, you must reenter the system configuration information and
reset the options each time the blade boots until you replace the battery.
Steps
1. Reenter the time and date through the System Setup.
2. Remove the blade from the enclosure for at least one hour.
3. Install the blade in the enclosure.
