1 Pre-Boot Diagnostics and BIOS Errors
BIOS Error Messages
If you miss the beep code, press and hold the power button for at least five seconds
until the modulated sound is emitted again. This “playback” of the memorized code can
also be used to diagnose an intermittent fault on a computer that appears to be working
again.
NOTE
Avoid disconnecting the computer’s power cord as this will delete some of the
computer’s error diagnostic information encoded in the modulated audio signal.
BIOS Error Messages
Error Message on
Screen
If your computer encounters a BIOS error, it will display a BIOS error message on the
screen, such as:
Error message 1 of 1: Error code 0103
Keyboard not detected - Keyboard error
Sometimes, recommendations for troubleshooting are also displayed below the error
message, or you need to press
Enter
to get the recommendations.
The error message and recommendations (if provided) can be used to troubleshoot the
problem.
Audio Error Signal
For many errors, some HP computers can also emit the modulated audio signal that
corresponds to the displayed error. This can be especially useful when you call your
support provider (this feature is described below in “Calling Your Support Provider”).
To emit the audio error signal, press
Enter
then
F11
