Laptop Keyboard takes in a lot of dirt, dust and grime. Occasionally cleaning the keyboard will make your laptop look nicer and preserve its life.
Start by turning your machine off. Unplug it, disconnect it and remove any USB wires or memory sticks.

For simple cleaning, tilt your laptop forward. Bang the back and hopefully anything lodged between the keys will fall out!
