Will not Boot, screen is black, no chime.
Out of nowhere, my MBP will not start. Here is what is happening.
1. I press the power button WITH the battery in. As long as I hold it down for a second or two, the front light is present as normal, then dims in about 1 second, then goes black in another second or two. While this is happening, I can hear the fan start, then it stops in 1-2 seconds. Also,I can hear what sounds like the drive start, then shutdown in 1-2 seconds. It almost sounds and responds identical to holding down the power button when forcing a shutdown. The screen stays black the entire time. No chime.
*Note: If I KEEP the power button pressed down, the light is present as normal, then dims in 1-2 seconds, and then starts flickering for 2-4 seconds, then goes black. The drive starts, the fan starts, but 4-5 seconds everything stops like it was a forced shutdown...screen is black, no chime.
2.When I take the battery out, but keep the wall plug in, nothing...at all. No lights, no noises of any sort. Nothing.
ANy thoughts?? Logic board?
Thanks in advance!
Edit: By the way, I have the NVIDIA GeForce 8600M GT graphics. Could this be the issue?
Edit 2: Magsafe light work fine. Also magsafe IS charging the battery, so that aspect is working fine.
Is this a good question?
