MBP 17" will not wake up from sleep
Closed the lid one evening. Opened it next morning and nothing happened. And whatever I try, nothing has happened since!
When I open the lid, the front LED is on (solid, not breathing), the fans run (quietly) and the hard drive runs (but I don't hear the heads moving).
I have removed the battery and power, left it for a day. No luck. Exactly the same. No chimes, no display, just LED, fans and (non-booting) disk.
I have used the tutorial here to remove the RAM battery as well.
Still the same.
I'm writing this question in the hope that there is another solution than a new logic board!
Any and all suggestions welcome.
