FAQ and troubleshooting

Why does the keyboard and/or palm rest get warm?
Typically, the Joybook tends to be warm slightly. The location of
the hard disk is typically underneath the palm rest and as a
result, the palm rest gets warm. The location of the processor is
typically underneath the keyboard. And since the heat rises, the
keyboard may get warm slightly. Since your Joybook has a
thermally controlled fan, when the CPU and/or internal
temperature of the Joybook reaches a certain temperature level,
the fan is turned ON and stays ON until the temperature drops
to a pre-defined level.
The U, I, O, P, J, K, L keys on my Joybook are coming up as
numbers instead of letters. Why?
The number keys are enabled. Press the Num Lk (Number
Lock) key once to disable the number lock function, and the
letters will return to normal.
There is no sound coming from the speakers.
Verify the following:
• The speakers may have been muted. Check the volume control
(speaker icon) in the notification area located in the lower
right corner of your desktop to see if the volume has been
muted. If so, please restore the volume.
• The speakers may have been turned off. Use the <Fn> + <F1>
hotkey combination to turn them on.
• The volume may have been set too low. Use the <Fn> + <F11>
hotkey combination to increase the volume.
• An earphone or external speakers may have been connected to
the audio output socket, turning off the Joybook's built-in
speakers automatically.
When a CD or DVD is inserted into the optical drive, there is no
response.
Verify the following:
• Your Joybook is turned on, and the CD or DVD discs are
properly inserted in the center of the disc tray in the optical
drive.
• The disc tray is closed.
• The CD or DVD is not bent or badly scratched.
• If you hear the noise from the optical drive when the disc plays,
the optical drive might be deformed, and the Joybook needs to
be repaired. If the disc tray does not open after the eject button
is pressed, insert a pointed object (like an opened paper clip)
into the tray ejection hole next to the ejection button to release
the disc tray.
DVD movies will not play.
The region code of the DVD inserted must match that of the
DVD playback software used. The region code can be changed 5
times before it is permanently locked to a region. Once the
region code is locked, you are only allowed to play DVDs with
the same region code as the last DVD played successfully.
