Starts with blank screen.. usually black, sometimes lit
This morning I woke my wife's Unibody MacBook Pro to find it warm with the fans running, a black screen and the sleep light on. Unable to wake it up, I powered down expecting to be able to recover it on restart.
This has happened a handful of times before, and up until now we've been able to restart and move on. However, today we are unable to resurrect this computer.
Most of the time the only thing I get on power-on is a black screen and a sleep light. No start-up chime or anything.
SOMEtimes I get a startup chime and a white screen, but nothing else... no "clueless Mac", no Apple logo, no pointer, nothing. Modifier keys (target disk mode, choose startup drive, recovery drive, etc) have no effect.
I've tried all the usual troubleshooting steps: reset SMC, reset NVRAM, reseat RAM, disconnect HD... no joy.
What am I missing? Is there any hope to recover this machine? I know the local Apple dealer will simply say "needs a new motherboard" without even looking at it, so that's not an option.
Any advice and/or help is appreciated.
Is this a good question?
