Leaving the screen idle for extended periods may result
in afterimages (screen burn-in) or ghosting. Turn off the
screen when you are not using the computer.
Features or options may differ depending on the model.
The items marked as optional may not be provided or
may be provided in different locations.
Since some storage space is reserved for system
recovery and operations, the available storage space
may be less than the actual capacity.
