5-10 Problem Solving
Incorrect or No Beep Code
Check the following:
! Is the speaker cable connected to the system board?
If the system operates normally, but there was no beep, the speaker may be defective,
contact your service representative for assistance.
Record the beep code emitted by POST, and see the “Messages and Beep Codes”
section found later in this chapter.
No Characters Appear on Screen
Check the following:
! Is the keyboard working? Check to see if the Num Lock light is functioning.
! Is the video display monitor plugged in and turned on?
! Are the brightness and contrast controls on the video monitor properly adjusted?
! Are the video monitor switch settings correct?
! Is the video monitor signal cable properly installed?
! Is the onboard video controller enabled?
If you are using a video controller board, verify that the video controller board is fully
seated in the system board connector.
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.
