32 Troubleshooting
Cause
RTC (real-time clock) battery may need
to be replaced.
NOTE: Connecting the workstation to a
live AC outlet prolongs the life of the
RTC battery.
Network driver is loaded and no
network connection is established.
The Num Lock key might be on.
Solenoid hood lock, featured on some
systems, is locked.
The panel is locked (xw6200,
xw8200, and xw9300).
Processor is hot.
Hard drive is full.
The customer has memory installed in
a single channel instead of in both
channels.
Solution
First, reset the date and time using
Computer Setup (F10). If the problem
persists, replace the RTC battery. See
the Service and Technical Reference
Guide for instructions on installing a
new battery, or contact an authorized
dealer or reseller for RTC battery
replacement.
Establish a network connection, or use
Computer Setup (F10) to disable the
network controller.
Press the Num Lock key. The Num Lock
light should not be on if you want to use
the arrow keys. The Num Lock key can
be disabled (or enabled) in Computer
Setup (F10).
Unlock the solenoid hood lock using
Computer Setup (F10). The solenoid
hood lock FailSafe Key, a device for
manually disabling the solenoid hood
lock, is available from HP. You will need
the FailSafe Key in case of forgotten
password, power loss, or workstation
malfunction. (Not applicable to the
xw8200 and xw9300)
Use the key located on the back of the
unit to unlock the panel.
1. Make sure the airflow to and from
the workstation is not blocked.
2. Make sure the fans are connected
and working properly.
3. Make sure the processor heatsink is
installed properly.
Transfer data from the hard drive to
create more space on the hard drive.
Ensure DIMMs are matched and
installed in both memory channels.
