Overview

Overview
What do you do if your computer does not start properly and you cannot run e-Diagtools
to diagnose the problem? The answer is to use e-Diagtools’ pre-boot diagnostic
capabilities or BIOS error messages.
If your computer powers on but does not start properly, it attempts to report the error
in two ways:
•
It emits a modulated audio signal followed by one or more distinct beeps – this is
pre-boot diagnostics
•
It displays an error message on the screen – this is a BIOS error.
Pre-Boot Audio Signal and Beeps
NOTE Pre-boot diagnostics are not provided on all HP computers.
The pre-boot audio signal can be used to identify the hardware component that needs
troubleshooting or replacement:
•
The modulated audio signal can be interpreted by a support provider equipped with
the Virtual Call Assistant. (For more information about the Virtual Call Assistant,
refer to the
Virtual Call Assistant User’s Guide , available on your HP computer’s
support web site – refer to page 7 for web addresses
)
.
•
The distinct beeps form a beep code that you can interpret using the following table:
Problem Number of beeps
If there is a buzzing sound:
• If you pushed the power button for more than 5 seconds, this is
normal; there is no error
• The power button may be stuck.
If there is no buzzing sound, the computer has no power. This could
mean:
• Computer is not plugged in
• Power supply failure
• System board failure.
