Basic Troubleshooting 27
Workstation date and time display is
incorrect.
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.
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.
Workstation appears to pause
periodically.
Network driver is loaded and no
network connection is established.
Establish a network connection, or use
Computer Setup (F10) to disable the
network controller.
Cursor will not move using the arrow
keys on the keypad.
The Num Lock key may be on. 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).
Cannot remove workstation cover or
access panel.
Solenoid hood lock, featured on some
systems, is locked.
Unlock the solenoid hood lock using
Computer Setup (F10). The solenoid
hood lock FailSafe Key, a device for

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

The panel is locked. (xw6200,

and working properly.
3. Make sure the processor heatsink
is installed properly.
Hard drive is full. Transfer data from the hard drive to
create more space on the hard drive.
