So I decided to buy a new 500 GB hard drive for my 2007 SR MBP - a WD Scorpio Blue. I put it in, booted from the Snow Leopard-DVD, formatted it and am currently using Time Machine to restore my backup. One thing strikes me as weird though: the left palm rest - the area directly over the hard drive - is extremely hot to the touch, and I do mean extremely, as in: I can't touch the surface of the MBP for more than a few seconds or it will be quite painful. What's the problem here? I'm sure the hard drive is put in (and screwed in) correctly; it was recognized and formatted, the top case sits flush, no screws are missing or in the wrong place... So what's causing this heat? Also, is it normal that this Time Machine restore says it will take five more hours (never done it before)? Thanks in advance for your advice.
