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.
2.
Turn off the system, and disconnect it from the electrical outlet for at least an hour.
3.
Reconnect the system to the electrical outlet, and turn on the system.
4.
Enter System Setup.
