...find out what type of keyboard it is. For some, the keys can be "poped up" for cleaning and poped back in. For some, the keys can be poped up, but can't be poped back in, requiring reassemble. Yet another type is a sealed unit and the only cleaning possible is the surface of the keys.
So, generally, cleaning is done by turning the laptop upside down, tapping the bottom (now upper side !)and just let the dust and debri (paper clips, pins and staples?)fall down. A portable vaccum cleaner or a can of compressed air may help... Finish off with a wipe with moist soft cloth - no excess liquid-(moisten with diluted light washingup liquid, or handwashingliquid.)all over-including the monitor screen, and clean off with a soft clean cloth moisten with warm water. Just be sure that the laptop is turned off. Leave to dry.
I have a laptop computer and I know my keyboard needs to be cleaned, The space bar is not working like it should. How do I get under the keyboards? To me it looks like that air dusters just blow dirt around and sometimes it makes it worse then better when it comes to jobs like this . Would a vacuum like a cordless dustbuster be ok to use? I used one of those computer vacuums but they really did not pick up anything. I read around other threads but nothing was asked about the cordless vac. Thanks in advance
