CD ROM Drive Troubleshooting

The following table lists several troubleshooting tips specifically for the optional CD-ROM drive.

Table 16 - CD-ROM Troubleshooting Tips

Trouble
The POWER switch is
ON, but nothing appears
on the CD-ROM display.
Call Center
Try manual undocking to get the
system apart. See dock User's
Guide (pg 1-13 English or
appropriate language's page) for
procedure. Send in dock for
repair.
In Control Panel, click on Power.
Power Management must be set
to Advanced. Has the computer
ever failed to resume and had a
dead battery (causing the clock
to stop)? If so, replace the
BIOS.
See: "Computer pauses and
won't permit keyboard or mouse
input for a few seconds."
Make sure cache is enabled in
SCU. If yes, then
press [Fn][+]. One beep
indicates slow mode, 2 beeps
fast mode. If problem persists,
send in for repair.
Can use Spin Rite 4 to
thoroughly diagnose the
problem.
If the RAM module does not
connect 1000% try another
module. A few of the RAM
modules received from the
vendor are out of alignment.
Possible Causes
The power cable is not
plugged into the
OmniBook connector or
the DC IN jack.
The batteries are not
installed correctly or are
dead.
Repair Center
Replace dock
Verify that Power Management
is set to Advanced. Test clock
accuracy with unit suspended.
If still not accurate, replace
logic and retest.
Verify problem and replace
CPU first, then logic board.
Solutions
Plug in the power cable correctly.
Install the batteries correctly or
replace with new ones.
