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
Reenter the time and date through the System
Setup.
Remove the blade from the enclosure for at least one hour.
Install the blade in the enclosure.
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 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.
