Troubleshooting
LifeBook notebook fails to
recognize DVD/CD-RW/
CD-ROM’s.
(continued)
Wrong drive designator was
used for the disc in the applica-
tion.
Verify the drive designator used by the application is
the same as the one used by the operating system.
When the operating system is booted from a DVD/
CD, drive designations are automatically adjusted.
Note that the drive designation can be changed with
the Disk Management tool located in the Control
Panel under Administrative Tools -> Computer
Management.
The optical drive access
indicator on the Status
Indicator Panel blinks at
regular intervals when no
disc is in the tray or the
drive is not installed.
The Windows auto insertion
function is active and is
checking to see if a disc is ready
to run.
This is normal. However, you may disable this
feature.
