1 Pre-Boot Diagnostics and BIOS Errors
Overview
12 English
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 Workstations.
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 6 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.
