Okay I know the title was strange but I don't know how to describe this problem, haha. So I am borrowing a friend's Macbook Pro for a month while I'm in New York. I've noticed two very strange things going on that don't affect the performance of the computer, but physically affect me using it. Hahaha. Okay so here goes: Whenever I rub the areas on the left and right of the trackpad it feels like it vibrates. You know how it feels when you run your finger over one of those holograms that they sometimes use for DVD cases, where you turn it back and forth and something animates? It has tiny ridges in it right, and it feels kind weird. That's what this feels like. The computer is not vibrating because it doesn't happen when my hand is sitting still on it, only when I move.. That doesn't bother me much I am just curious as to what is going on.. I'm not crazy! The second, more annoying issue that really confuses me is that sometimes when I rest my forearms on the edges or corners on the front of the laptop, on either side of the trackpad like when I'm typing, I suddenly get this pin prick feeling or like a strong static shock. It's right on the edges of the laptop. I have no idea what is happening. I was thinking maybe it was a hair in my arm getting somehow hung in a crevice (this is not the unibody MBP), but it happens on both sides of the computer.. It's like a pin prick or a shock or a slight burn, as if you touch a hot mug before it cools down.. What is going on?! is my Macbook haunted? Also is it common for the internal mics on these things to stop working? I heard that the new models have bad mics, but this is an older one (multi-piece body) and the mic used to work fine, but now when I video chat with people they say it sounds like I'm whispering. I even tried recording myself and it is indeed very faint... What gives?
