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 re-
enter the system configuration information and reset the options each time the blade boots until you
replace the battery.
Steps
1. Re-enter 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.
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 the Getting help section.
