Many times, keyboard keys on laptops become stuck or damaged or fall off of your laptop. By following basic laptop cleaning and repair steps, you can avoid costly keyboard or computer repair costs through conducting do-it-yourself repair steps. If you do not address keyboard issues with your laptop at the outset and begin to lose multiple keyboard keys, there could be potential damage to the interior components of the laptop case, which ultimately could cause catastrophic damage to your computer.
Purchase compressed air used for keyboard cleaning and spray around the laptop keyboard keys. This will ensure that all debris, food and gummed liquids will be removed from underneath your keyboard keys.
Replace keys that have fallen off of the keyboard with superglue by placing a small amount of glue on the circular plastic mold on the back of the key and press directly down in the correct place on the keyboard.
Pull any keys from the keyboard that have been problematic and inspect the plastic retainer on the back of the key. Pull the retainer from the key, clean with compressed air, replace back on the key and re-install on the keyboard by pressing down on the laptop keyboard.
Consult the operator manual for your laptop to order a full replacement keyboard if your laptop keyboard continues to malfunction.
