I've had this laptop 4 yrs and have never cleaned the fan or vents...or anything. Recently had overheating and shut downs. I had hoped there'd be a panel to the fan but I think not. Every vid on youtube involves what looks like almost complete disassembly of the laptop. I don't know what I'm doing and don't feel comfortable disassembling my entire laptop. Yet I'm certain I have a big mat of cat hair and dust blocking my exit vents.
What's the minimum I have to take apart to clean the vents and fan? Photos &/or diagrams and instructions showing what screws to remove etc would be great. I'm a fairly confident user but have never done any type of laptop or electronics fiddling. Is this something a careful newbie can tackle w/o getting into trouble?
Thanks!
