Yesterday I I closed the lid on my MacBook Pro, early 2008, 2.4 C2D. When I opened it, nothing happened. When I try to power it on, the sleep indicator comes on for a few seconds, the fans spin up and the dvd drive clicks, no chime. I haven't been able to get it to do anything more than that. It's been running solid with no problems. Any ideas what it could be? Is it worth putting a replacement board in? I'm "having" to type this on a Thinkpad T61. which I'd already decided would be my keeper Windows Machine.
