Why does the keyboard and/or palm rest get warm?
Typically, the Joybook tends to be sli ghtly warm. The l ocation of the hard
disk is typically underneath the palm rest and as a result, th e palm rest
gets warm. The location of the processor is typically underneath the
keyboard and since heat rises, the keyboard may slightly get warm. There
is no need to be concerned. However, since your computer has a
thermally controlled fan, when the CPU and/or internal temperature of
the notebook 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?
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.
Check the following:
• The speakers may have been muted. Look at the volume control
(speaker icon) on the Windows Taskbar to see if mute has been set. If so,
turn off the mute.
• 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 be connected to the audio-out
socket, automatically turning off the computer's internal speakers.
