Overheating laptop
I've been using my laptop here at Uni and since i've been here i've noticed alot of dust and crap collecting underneath in the air vents, which I have to regularly blow out.
The room has rubbish ventilation which has resulted in everything getting caked in deoderant mainly. It's not 'cos i'm a dirty bugger who doesn't clean...
The laptop is getting very hot very quickly, the USB connectors at the back get very hot (Flash sticks, USB mouse etc), and the fans go into overdrive, making it sound like it's about to take off. Also it's a bit slow, could it be due to the overheating?
The laptop is a Dell Inspiron 9100, which after reading the odd bit of info on it i've discovered it has quite a big cooling unit.
My question is, how do I go about cleaning the laptop out? Does it sound like this is the problem i'm having? And is there any way to have it cleaned out by someone who knows what they're doing, as i'd be a bit reluctant to open the thing up myself.
Any advice on it would be much appreciated.
