Question

Macbook Pro boots up to blank screen but changes when the lid is closed and opened.

My MacBook Pro with Retina display, OS X Yosemite (10.10), ME664LL/A 15.4-Inch starts up with a black screen when I press the power button. I hear the Apple chime but there is no Apple logo or progress bar.

However while trouble shooting and researching I found out that if I close the lid of the MacBook for 30 seconds and then open it i get the log in screen asking for my password. When I put in my password the MacBook functions normally.

I also found out that if I press the power button and leave the Macbook open for half an hour or so and then press the space bar I get the log in window asking for my password.

Just to say the macbook will boot up normally sometimes.

You can try running the Diagnostic/AHT http://support.apple.com/kb/HT1509

However, not definitive by any means, but may kick out an error code.

In or out of warranty you can get a free over the counter 'Apple Service Diagnostics' test

Thanks for your response. I tried all these keyboard configurations already during my research. I am beginning to think it might be a hardware problem.

Thanks. Will try this. To note I tried to restart holding down the ‘D’ key and the computer refused to start up. It remained totally blank.
