Caring for your ThinkPad computer Cleaning your computer keyboard 1. Absorb some isopropyl rubbing alcohol on a soft, dust-free cloth. 2. Wipe each keytop surface with the cloth. Wipe the keys one by one; if you wipe several keys at a time, the cloth may hook onto an adjacent key and possibly damage it. Make sure that no liquid drips onto or between the keys. 3. Allow to dry. 4. To remove any crumbs and dust from beneath the keys, you can use a camera blower with a brush or cool air from a hair drier. Note: Avoid spraying cleaner directly on the display or the keyboard. 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 or the TrackPoint® pointing stick 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. Cleaning the touch panel display 1. To remove fingerprints, etc., from the touch panel display, use a dry, soft, lint-free cloth. (A piece of absorbent cotton will also serve the purpose.) Do not apply solvents to the cloth. 2. Gently wipe foreign particles and dust from the touch panel with one side of the cloth. 3. Wipe smudges or fingerprints with the other side of the cloth, or with a clean cloth. 4. After using the cloth, wash it with a neutral detergent.
