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 speakers may have been turned off. Use the <Fn> + <F7>
