Power light turns on but screen remains black. No chime.
This has been happening intermittently for the last month or so.
Sometimes, when the screen goes into sleep mode the keyboard will remain backlit. When I press a button or click to bring it out of sleep mode the computer will be unresponsive. My only option from there has been to hard reset the computer. Usually this works, but sometimes, on reset, the computer will power on (I can hear the optical drive sound, fans, and see the power light) but remain at a black screen. It does not chime.
I have tried smc resets, pvram resets, booting into recovery, and booting into safe mode. All are unresponsive. I also used the apple hardware diagnostic and it passed (mine and at an apple service center). I updated the ram to 8gigs and the hard drive to an ssd(trim is enabled) over 6 months ago.
The computer is running El Capitan and I'm usually running rails console or IPython when it crashes (though I'm running those most of the time).
Is this a good question?
