Use a soft cloth to remove dirt on the display. The touchscreen surface has a
special protective coating that prevents dirt from sticking to it. Not using a soft
cloth may cause damage to the special protective coating on the touchscreen
surface.
Turn off the computer power when cleaning the display. Cleaning the display
with the power on may cause improper operation.
Do not use excessive force on the display. Avoid placing objects on top of the
display as this may cause the glass to break thereby damaging the display.
In low and high temperatures (below 5
o
C / 41 °F and above 60
o
C / 140 °F), the
touchscreen may have a slower response time or register the touch in the
wrong location. It will go back to normal after returning to room temperature.
When there is noticeable discrepancy in the operation of the touchscreen
function (wrong location on intended operation or improper display resolution),
refer to the Windows online Help for instructions on recalibrating the
touchscreen display.
