Problem
===========================================================================
Computer won't turn
on and battery pack
is not inserted.
---------------------------------------------------------------------------
Computer turned off
while it was left
unattended and the
power icon is off.
Probable Cause
Incorrect device driver
or no device driver is
installed.
The device driver is not
installed in Windows.
An external pointing
device is connected
and the system has
disabled the internal
pointing device.
The panastick
technology can sometimes
exhibit this behavior.
Probable Cause
Computer is not

Power cords to the
external power source
are unplugged.
Power board is
defective.
System initiated
Hibernation due to a
critical low-battery
condition.
Solution(s)
Install the device driver
and add to the
AUTOEXEC.BAT file or
CONFIG.SYS file.
Install the device driver
in Windows.
Initiate Standby and
disconnect the external
pointing device.
If the cursor starts
drifting, stop using it
for a few seconds. This
will stop the cursor

resume normal operation.
Solution(s)
Insert battery or connect
an external power source.
Ensure that power cords
connecting the computer
and the external power
source are plugged in
properly.
1. See Table 2-27 and
Figure 2-2 to check
for proper voltages.
2. Replace power board
and restart.
Replace the battery pack
with a fully charged
battery pack or connect
the computer to an
