2. Wipe each keytop surface with the cloth. Wipe the keys one by one; if you
wipe several keys at a time, the cloth might hook onto an adjacent key and
possibly damage it. Ensure that no liquid drips onto or between the keys.
3. Allow the keyboard to dry.
4. To remove any crumbs and dust from beneath the keys, use a camera
blower with a brush or cool air from a hair drier.
Clean the computer display
To clean the computer display, do the following:
1. Gently wipe the display with a dry, soft, lint-free cloth. If you see a
scratchlike mark on the 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.
Note: Avoid spraying cleaner directly onto the display.
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.
Keep the following in mind:
• Only an authorized Lenovo repair technician should disassemble and repair
your computer.
• Do not modify or tape the latches to keep the display open or closed.
