I've been using an Exo silicone protector in my white macbook keyboard for about 3 months and I think it is causing some overheat in the laptop. I've written this thread some time ago but I cancelled it cause I was afraid of making so much noise for nothing. But now I think the problem can be really serious. I've noticed some black spots (they look like the kind of one that appears when you put fire close to your hand or something white), when I put off the protector to clean the laptop. The spots disappeared the first time I cleaned up, and I decided to cancel the thread. I don't want one more paranoid thread. Yesterday I've put off the protector again and noticed the same kind of spots around the same places - and I guess there are more this time. It was very difficult to remove the spots using the Omniz Cleaner and I didn't get all the keys cleaned. When you look at the protector out of the lap, you can see some dark areas right on the same keys that became "burnt" ! Do you think this protector is burning the keyboard ? I always use Istat pro to check the temps and never gets beyond 65 C. Anybody here with the same problem ? I took some pictures but deleted them with the last thread. I'll make new one and post when I find a friend with a digital camera.
