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

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 kept in the System Setup program, the problem
may be caused by software rather than by a defective battery.
Troubleshooting PSUs
1.
Identify the faulty PSU by the PSU’s fault indicator. See
Power and system board indicator codes
.
CAUTION: At least one PSU must be installed for the system to operate. Operating the system
with only one PSU installed for extended period can cause the system to overheat.
2.
Reseat the PSU by removing and reinstalling it.
NOTE: After installing a PSU, allow several seconds for the system to recognize the PSU and to
determine if it is working properly. The power indicator glows green to signify that the PSU is
functioning properly.
If the issue persists, replace the faulty PSU.
