Troubleshooting a Power Supply
CAUTION: See your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting
against electrostatic discharge.
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 kept in the
System Setup program, the problem may be caused by software rather than by a defective battery.
