Troubleshooting guide

Problem Probable Cause Recommended Solution
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 plug and play board may
not automatically configure
when added if the default
configuration conflicts with
other devices.
Use Computer Setup (F10) to reconfigure or disable devices to resolve
the resource conflict.
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. If you still cannot resolve the issue, contact Customer Support.
3. Observe the beeps and LED lights on the front of the workstation.
See
Diagnostic Lights and Audible (Beep) Codes to determine
possible causes.
Workstation will not shut
down.
Proper steps must be
followed.
1. Shut down the operating system software.
2. Manually turn off power to the workstation by pressing and holding
the power button for four seconds.
CAUTION Manually turning off the power bypasses the
standby state and can result in loss of data.
3. To reconfigure the power button to work in On/Off mode, run
Computer Setup (F10).
For more information about using Computer Setup, refer to the Service
and Technical Reference Guide, which is available through a link on
