Solving System Problems 5-13
Is the video monitor signal cable properly installed?
Is the onboard video controller enabled?
If you are using an option video controller board, perform the
following steps:
1.
Verify that the video controller board is fully seated in the
system board connector.
2.
Run the BIOS Setup utility to disable the onboard video
controller.
3.
Reboot the system for changes to take effect.
If there are still no characters on the screen after you reboot
the system, contact your service representative or authorized
dealer for assistance.
POST emits one long beep and two short beeps pattern to
indicate a possible problem with the video display controller.
If you do not receive a beep pattern and characters do not
display, the video display or video controller may have failed.
Contact your service representative or authorized dealer for
assistance.
