Cause
Software control of the
power switch is not
functional.
Workstation is in
Standby mode.
RTC (real-time clock) battery
might 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
(xw6000/xw8000/xw9000
series).
Press and hold the power button for at least four seconds until the
workstation turns off.
Press the power button to resume from standby mode.
CAUTION: When attempting to resume from standby mode, do not hold
down the power button for more than four seconds. Otherwise, the
workstation shuts down and you might lose your data.
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
