Hi, I just sent my sick gaming PC in for repairs and I'm busting out the old trusty laptop. It is a XPS m11710 I think. It has this problem where every six months or so the inside needs to be dusted because the fan sucks in a ton of gunk. It literally bottlenecks the whole system, and using compressed air doesn't seem to work. Is there anyway to easily open it up and get to the CPU, I don't want to completely dismantle the whole thing and possibly ruin it. I swear they make laptops so anti-user friendly so you just have to buy a new one, when they break.
