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.
CD or DVD does not function.
Please verify the following:
• 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.
• Noise from the optical drive when the disk plays shows that the
optical drive may be deformed, and the computer needs to be
repaired. If the disc tray does not open after the Eject button is
pressed, insert a pin into the Emergency Eject hole to force the
tray out.
DVD movies will not play.
The region code of the DVD inserted must match that of the
DVD playback software used. This region code can be set up to
five times. If you have not reached this limit, a prompt will
appear that will allow you to change the region code of the
software to match that of the move. Otherwise, you can only
play back DVDs with the same region code as the last DVD
played back successfully.
Why is the hard drive capacity displayed by the OS be different
from its nominated capacity?
Most users may have discovered that the capacity of a 10GB
hard drive will become 9GB when displayed from the OS; and
20GB become 19GB, 40GB become 38GB..., etc. The bigger the
capacity, the bigger the difference. It is because hard drive
makers and OS developers calculate hard drive capacity in
different ways. As a result, the nominated capacity is different
from the exact capacity displayed by the OS.
