How can I use the LEDs on the front
panel to troubleshoot my PC?
!
The LEDs on the front panel indicate the various states your PC is
in.
The On/Off LED indicates the power modes status of your PC. The
three states are: green (PC is on), blinking green (PC is
suspended) and off (PC is off).
The Lock LED indicates whether your PC is locked or not. The two
states are: orange (PC is locked) and off (PC is not locked).
I have an event log which says that the
RPC hung. What can I do?
!
This is because Windows NT SP6a uses 99% of the CPU. This
bug has been acknowledged in the Microsoft knowledge base (Ref
Q266208 available on: http://support.microsoft.com/support/kb/

The problem does not occur with SP5, this is why the hp VL400
comes pre-installed with SP5.
Why are the beep codes from the
e-DiagTools pre-boot diagnostics feature
reporting a null serial number and PCID
on my VL400?
!
If the PC is unplugged and then plugged in again, both the serial
number and PCID are lost (reset to zero). If, subsequently, a pre-
boot failure occurs before the BIOS has been able to boot the PC
(and refresh the serial number and PCID in the micro-controller),
you will see a null serial number and PCID in the Virtual Call
Assistant.
The suggested workaround to this issue is to communicate the
serial number and model information over the telephone.
