Power Light Does Not Light
Check the following:
Are all the power supplies plugged in? Is the power turned on to the power strip or outlet? Do
you have a blown fuse or breaker?
Is the system functioning normally? If so, the power LED may be defective, the cable from
the front panel to the fan board is loose, or the cable from the fan board to the baseboard is
loose.
Are there other problems with the system? If so, check the items listed under "System Cooling
Fans Do Not Rotate Properly."
If all items are correct and problems persist, contact your service representative or authorized
dealer for assistance.
No Beep Codes
If the system operates normally, but there was no beep, the speaker may be defective. If the
speaker is enabled, but the speaker does not function, contact your service representative or
authorized dealer for assistance.
Record the beep code emitted by POST, and see "Error and Informational Messages" on page 77.
No Characters Appear on Screen

Is the keyboard working? Check to see that the "Num Lock" light is functioning.
Is the video monitor plugged in and turned on? Many modern video monitors shut down when
