Why does the keyboard and/or palm rest get warm?
Typically, the Joybook Lite 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 Lite has a thermally controlled fan, when the CPU and/
or internal temperature of the Joybook Lite reaches a certain
temperature level, the fan is turned ON and stays ON until the
temperature drops to a pre-defined level.
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 the 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> + <F7>
hotkey combination to turn them on.
