case, restart the system using the power switch; then turn the power supply off from a
software application or from Windows.

configuration.)

System Clock Faults
System Time Deviates, Even After Being Set Correctly

characteristic of Windows NT is that the time deviates when the system enters the standby
mode.
❏
Confirm whether replacing the main circuit board solves the problem.
