how can i clean my laptop , what is most important?

Forest Duttinger: Get a wet wipe and just clean the whole thing. No damage should be done with a wet wipe unless you pour water on it.

Douglass Sarley: The most important thing when it comes to laptop cleaning is the ventilation shaft along the laptop heatsink , it usually gets filled with dust and dirt and when it does it is preventing the airflow through the ventilation and ribs of the heatsink so your laptop cannot cool and after some time it may even start to shut down or overheat and stop working so best way to do it is to unscrew the bottom plastics , find the heatsink and blow away the dust and dirt .

Tijuana Tatsak: Physically clean? Just use a damp cloth for the outside. They make some special wipes for cleaning screens of HDTVs and laptops, you can buy them anywhere-Walmart for example. And use a can of compressed air to clean the keyboard. If you must use a damp cloth to clean the keyboard make certain the computer is turned off first so nothing get! s wet and shorts out.
