Frequently Asked Questions 2of11

When I boot my PC under Windows 98, a

message indicates there is a registry

error and that Windows will fix the

registry. What should I do?

!This bug is documented at:

http://support.intel.com/support/chipsets/storagedrivers/ultraATA

To fix this problem, install the latest IDE driver on HP’swebsite

(version 6.01.007 or later). Ensure that you install the chipset

driver before the IDE driver.Models purchased after November 1st

2000 are supplied with the correct driver.

My PC runs scandisk when I boot under

Windows 98 SE even if the previous

shutdown appeared to finish normally.

Why?

!Sometimes your PC may appear to shutdown successfully when it

it has not. In these cases the operating system thinks that

Windows has been shutdown incorrectly and runs scandisk.

A patch for this problem can be found at:

http://support.microsoft.com/support/kb/articles/Q273/0/17.ASP

Why doesn’tmyPCstartwhenusinga

console switch? !This only applies to switches that internally connect both power

lines of the PS/2 mouse and keyboard.To solve the problem, use

one mouse for each PC connected to the console switch.

Why does my PC emit a long series of

beeps during the boot process when my

screen remains blank?

!The beeps are created by the HP e-DiagTools Pre-boot

Diagnostics utility. For an explanation of the beep codes, refer to

page 56.

When I started my pc the first time, the

mouse scrolling wheel did not work. Is

there a problem?

!This only affects some Windows 95 users. If the machine is

rebooted, the scrolling wheel will function correctly and the

problem will not show up again.

Frequently Asked Questions 3of11

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/

articles/Q266/2/08.ASP?LN=EN-US&SD=SO&FR=0)

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.

Problem with recovery CD-ROMs:

Why does my Image Creation and

Recovery CD not create the utility

partition correctly?

!This feature cannot work independently. First, create the HP utility

Partition. Then, create your main partition and install your

preferred operating system. Your HP Utility Partition should now

be ready for use.

Note: This problem only affects HP Image Creation and Recovery

CDs with the part numbers 5970-0170-xx and 5970-0190-xx.

When using the Image Creation and

Recovery CD-ROM, the PC stops. Why? !When the BIOS setup field "State after power failure" is set to "Off"

the PC stops and does not reboot correctly. To solve the problem,

manually power on the PC and continue the recovery process.

Why is my PC not booting from the

CD-ROM? !It is likely that some BIOS-level settings (boot device order,

security settings etc.) do not have correct values. Restart your PC

and enter the Setup program by pressing the appropriate function

key (F2 on most HP PC models, or F1 on others). Change the

incorrect settings, then try booting from the CD-ROM again.

It is also possible that the CD-ROM drive is not connected

properly.
