Solving Hardware Installation Problems
You might need to reconfigure the workstation when you add or remove hardware, such as an additional
diskette drive. If you install a PnP device, Windows XP automatically recognizes the device and configures
the workstation. If you install a non-PnP device, you must reconfigure the workstation after completing
installation of the new hardware. In Windows XP, use the Add Hardware Wizard and follow the on-screen
instructions.
Table 5-32 Hardware Installation Problems
Problem Cause Solution
A new device is not recognized
as part of the system.
Device is not seated or
connected properly.
Be sure that the device is properly and securely
connected and that pins in the connector are not
bent down.
Cables of new external
device are loose or power
cables are unplugged.
Be sure that all cables are properly and securely
connected and that pins in the cable or connector
are not bent down.
Power switch of new external
device is not turned on.
Restart the workstation, turn on the external device,
then turn on the workstation to integrate the device
with the workstation system.
When the system advised
you of changes to the
configuration, you did not
accept them.
Reboot the workstation and follow the instructions
for accepting the changes.
A PnP board might not
automatically configure
when added if the default
configuration conflicts with
other devices.
Use Windows XP Device Manager to deselect the
automatic settings for the board and choose a basic
configuration that does not cause a resource
conflict. You can also use Computer Setup to
reconfigure or disable devices to resolve the
resource conflict.
Device hardware is not
properly jumpered or
otherwise configured.
Read the device-specific configuration information
and check for incorrect settings or conflicts with
other devices already installed in the system.
Workstation will not start. Wrong memory modules
were used in the upgrade or
memory modules were
installed in the wrong
location.
1. Review the documentation that came with the
system to determine if you are using the correct
memory modules and to verify the proper
installation.
2. Observe the beeps and LED lights on the front of
the workstation. Refer to “Power On Self Test
(POST) and Error Messages” on page 165 to
determine possible causes.
Beeps and power LED flashes
RED five times.
Memory is installed
incorrectly or is bad.
1. Reseat DIMMs.
2. Replace DIMMs one at a time to isolate the
faulty module.
3. Replace third-party memory with HP memory.
4. Replace the system board.
