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.
NOTE:
If the system 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 system time to speed up or slow down. If the system seems to operate normally
except for the time set in System Setup, the problem may be caused by a software, rather than by a defective battery.
Steps
1. Re-enter the time and date in System Setup.
