Verifying Proper Operation of Key System Lights
As POST determines the system configuration, it tests for the presence of each mass
storage device installed in the system. As each device is checked, its activity light should
turn on briefly. Check for the following:
1. Does the diskette drive activity light turn on briefly? If not, see “Diskette Drive
Activity Light Does Not Light”.
2. If system LEDs are illuminated, see “LED Information” for a description of the light
and steps to take to correct the problem.
Confirming Loading of the Operating System
Once the system boots up, the operating system prompt appears on the screen. The
prompt varies according to the operating system. If the operating system prompt does not
appear, see “No Characters Appear on Screen”.
