2008 15 inch MacBook Pro...I was in the middle of a game of UT2004 (nostalgic!), and it suddenly, quite literally instantaneously, powered off. The battery was 100% charged, but it did not remain powered on. Tried to power it back on normally after it cooled down (I figured it might have overheated), but to no avail. I pulled the battery out and let it sit overnight. Still nothing this morning. I mean absolutely nothing, no indication whatsoever that it is even trying to power on. So, what do you think? I think it's gone. In the meantime I'm using an original MacBook Air I had in storage, and I still have my MacPro of course. Suggestions? I plan on taking it to a shop for diagnosis, but I'm pretty sure any repair would go beyond what the machine is worth. Shame. I just put an SSD in it.
