Troubleshooting System Cooling Problems
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.
CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system.
Before performing any procedure, see your Product Information Guide for complete information about safety precautions, working inside the
computer and protecting against electrostatic discharge.
