macbook pro turns on but screen stays black — my solution

The Apple Macbook Pro would turn on, but the screen would not.  The screen would stay black.  I could tell the computer was on because when I hit the “caps lock” key, the green light on the key would turn on and off.

I fixed this the following way (this is basically resetting the Power Management Unit — PMU):

I disconnected the computer from the power cord, and from all other cables.

I held down the power button for several seconds to turn off the computer.

I let it sit 5 minutes.

I restarted the laptop while holding down the Shift key.  This restarted the computer in Safe Mode, with the screen visible again.

After I logged in (in Safe Mode) to make sure everything was ok, I simply restarted the computer the normal way, and the screen behaved normally again.

=================================

If that doesn’t work for you, you could try these steps, documented at apple.com:

Holding down Command, Option, P, and R to reset your PRAM and NVRAM

    Before going and buying a new motherboard for 1000$. Have just the video card chip replaced for 150-250$. eBay/google it. I got mine fixed that way and it runs perfect now! Also Apple has a recap on that which is expiring this year sometime(2016)

    Hello. I woke up this morning to a macbook pro ( 2.4 GHz core 2 duo/2GB/256MB VRAM 200GB ) that had a black screen. I’ve gone through many of the fixes listed on this site but so far, nothing has worked fro me. Do you have any other options I can try?

  15. This solution worked, but at first I was too impatient to notice.
    Started up in Safe Mode, but only saw a very dim “something” appear
    on the screen of my 2006 MacBookPro 1.1. So I tried other solutions I found posted. None worked.
    But finally returned to this safemode startup. …and once again, the very dim
    something appeared. I got distracted by another chore which probably took
    5-10 minutes. When I got back to the MBP, the screen was nice and bright.
    I logged in….everything worked. So I restarted, which happened more slowly than expected.
    So I zapped the PRAM and now everything is back to normal….THANK YOU! THIS IS A LIFESAVER!

    Hi there, the “shift-restart-version” did the trick for me, so many thanks, wonderful, I had been really desperate…

    Ok, I tried this. At first I thought it didn’t work because starting in safe mode was the same as starting normally. I was unhappy, however I tried turning it on again after waiting a minute and it started fine.
    I’ll also say the problem was the computer was technically on but the little start up noises never happened and the computer screen stayed black.
