Cleaning your computer display
1
Gently wipe the display with a dry, soft lint-free cloth. If you see a
scratchlike mark on your display, it might be a stain transferred from
the keyboard when the cover was pressed from the outside.
2
Wipe or dust the stain gently with a soft, dry cloth.
3
If the stain remains, moisten a soft, lint-free cloth with water or a 50-50
mixture of isopropyl alcohol and water that does not contain
impurities.
4
Wring out as much of the liquid as you can.
5
Wipe the display again; do not let any liquid drip into the computer.
6
Be sure to dry the display before closing it.
