plugged into an external power source.
■
Stop or remove a optional external media cards that you are
not using.
■
Remove a CD or DVD that you are not using.
■

as you need it.
■
Use optional powered speakers instead of the internal
speakers, or adjust system volume as you need it.
■
Turn off a device connected to the S-Video-out jack by using
