My MB has been making funky fan noises for a while now, but always intermittently. Today it started again so I rushed off to the computer repair center on campus to show them....only two days left on Applecare so I needed to get it fixed....but they kept my computer! I thought they'd diagnose it really fast and order parts and I could bring it in and get it fixed later but they kept it. Now I am completely computerless and already I know that the next few days are going to suck.... I'm using a PC in the honors computer lab at the moment but it's driving me nuts... how much diagnosing need sto be done when a fan sounds like someone is riding a bike with a card stuck in to the spokes? But the guy claims "we gotta diag' it."
