So my machine was working fine all day. I installed a yep(the PDF management app) trial and the app locked up so I tried to quit the app. It removed itself from the dock but wouldn't disappear from the desktop. I tried to do a reboot but it got stuck so I held down the power button. I then tried to reboot and it kinda got stuck in some kind of loop and I had to unplug some peripherals and it eventually shutdown. But now it won't boot. I press the power button and it just shuts down. I tried resetting the PRAM and the SMC and neither worked. I had replaced the ram a long time ago (January of this year) and thinking maybe it was the RAM I swapped back in the old Apple RAM with the same result. I can hear the CD drive spin but I cannot I hold it down and the indicator light flashes but after a few seconds the machine shuts off. With my battery being full I am convinced that either the logic board is dead or the hard drive crashed. I do have AppleCare and I do have an appointment tomorrow but my question is assuming the worst and the logic board is dead, is this covered under AppleCare?
