First of all, I am becoming way to used to going to the Genius Bar with this machine. I have an early 2008 MacBook Pro and it has suffered around 4 or 5 hard drive failures since then, had it's logic board and super drive replaced, and is still giving me a headache. The last time the Genius Bar replaced the HD on my MBP was on New Years Anyways, here's what's going on. I woke up this morning ready to tackle writing my college admissions essay. I open my MBP up (I always leave it on), and nothing happens. Okay, I press the power button and nothing happens again! Oh no. I don't hear the HD spin, actually, the machine emits no noise whatsoever. I tried all the suggested steps online that I could find including this one (Troubleshooting a MacBook, MacBook Air or MacBook Pro that won't turn on: http://support.apple.com/kb/TS1365) and it still won't power up I made an appointment with the Genius Bar at 2:00 PM today but I'm wondering if I could do anything to figure out what's wrong so I don't have to do the now ritual 45 minute drive north to Reno. Yikes.
