Optical Drive Problems

LIFEBOOK fails to
recognize Blu-ray/DVD/CD-
RW/CD-ROM's.
Possible Cause
The volume is turned too low.
The software volume control
is set too low.
Headphones are plugged
into your notebook.
Software driver is not
configured correctly.
The speakers have been
muted using the Volume icon
in the system tray.
The disc is not pushed down
onto raised center circle of
the drive.
Optical drive tray is not
latched shut.
Incorrect or no DVD Player
software is installed.
Wrong drive designator was
used for the disc in the appli-
cation.
Possible Solutions
Adjust the volume using the [Fn+F9] key combination on your keyboard. Press
[F9] repeatedly while holding [Fn] to increase the volume of your notebook.
Manually adjusting the volume (i.e. keyboard "hot keys") should dynamically
adjust the volume of the operating (see above). If that doesn't work, adjust the
sound volume control settings in your software or application.
Plugging in headphones disables the built-in speakers, remove the head-
phones.
The Audio Driver may be installed or reinstalled by using the FSDM utility. See
"Maintaining Latest Configuration" on page 10. Refer to your application and
operating system documentation for help.
Click on the Volume icon in the tool tray on the bottom right of the screen. (It
looks like a speaker). If the Mute box is checked, click on it to uncheck it. You
can also use the [Fn+F3] key combination to toggle the volume on and off.
Pressing [F3] while holding [Fn] will toggle the audio mute.
Open optical drive tray and re-install the disc properly.
Push on the front of the optical drive tray until it latches. If that doesn't work, pull
out the modular drive latch, remove the device from the bay, then re-insert the
drive until it latched; this ensures that the drive is properly seated.
Install DVD Player software. (See "Media Player Software" on page 64 for more
information.)
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 at Administrative
Tools > Computer Management.
