There are actually many reasons why laptop keyboard problems due to contamination occur, with the common causes being spilled liquids, loss of lubrication, weakening of the rubber pieces in the individual keys, and dust and hair.

The following procedure will help solve these laptop keyboard problems and restore your keyboard to perfect working order:

• First, pry each key loose with a screwdriver and set them aside, making sure you don’t lose the small rubber pieces that come with each key.
• Clean the keyboard with cotton swabs dampened with only a little water. For the tight spots, you may have to use small pieces of foam and tweezers to reach in.
• Repeat this cleaning process with alcohol and cotton swabs.
• Clean the key contacts a third time with lighter fluid.
• Next, clean keys the individual keys themselves with lighter fluid, making sure that all the grease is removed. Follow this with household cleaner and let dry, after which you should rinse them with hot water and leave them to dry again.
• The rubber components should be cleaned with household cleaner and left to dry for 5 minutes. Rinse them with hot water and leave them to dry.
• Lubricate the keys with dry film lubricant, making sure that you get the lubricant into all the small spaces. Let the keys dry thoroughly. Make sure that you lubricate the keyboard and the rubber components as well.
• Reassemble the keyboard by first replacing all the rubber components and then the keys with wires. Snap the wire in securely and then snap the other keys into place.

That’s it! If all went well, you will now have a perfectly functioning keyboard!
