pretty simple like browning said. take all the screws out of the bottom but please dont yank it apart if its tough to come apart from the top part. troubleshoot and do it yourself will save you time and money. take it to a computer shop or a store somewhere will rip you the f off. i worked as a computer technician as my last job and seen it. its business yeah. laptops are not that bad to work on as some people think. just go to walmart and get the yellow case of small screwdrivers for like $5 or something. they work perfect. hey if you cant fix your fan just shop on ebay for one im sure they are a couple bux. DIY ftw...
