Troubleshooting The System Battery

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 came with the 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.

2. Turn off the system and disconnect it from the electrical outlet for at least one hour.

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, the problem may be caused by software rather than by a
defective battery.
