Well, the subject pretty much says it all Well, all day today, the fans on my mid-2007 Macbook pro have been hovering around the 3000-4000 rpm range, when they normally stay at around 2000 rpms, also my battery life seems to have taken a drastic step for the worst. I can usually pull about 2-3 hours on one charge, but today, it shockingly dropped 50% in just a half hour! This is all with very minimal application use. I have just been running firefox and Pages all day. Any idea what could be going on? The only significant change I made was to partition the hard drive via boot camp so I could install windows and get sling player mobile working, but thats it.... I'm a bit concerned needless to say as I really enjoy this computer and can't really function without it(studying graphic design in college at the moment). Thanks!
