I had a similiar problem with my mac it just wouldnt boot no matter what, i disconnected all the power from the mac and from the mains and left my mac for about 10 mins then plugged it back and it booted straight up, it happened twice to me and was quite strange.

might need a pmu reset,

shut down, then unplug it
open up the case
on the bottom left side of the logic board is a button labeled S1
hold that button for a second or two
put the case back together
wait at least 10 seconds before plugging back in
try and start it up

its really pretty simple i just saved one of our computers at work by doing this, its worth a try

- - pm me if you want an invite i have a few left
QUOTE Thanks
