Troubleshooting the NVRAMbackup battery

Prerequisites
CAUTION: Many repairs may only be done by a certified service technician. Youshould 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 yourproduct.
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 andreset 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.
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.
NOTE: If the blade 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 blade's time to speed up or slow down. If the blade 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.
