Question: MacBook cannot boot up, even in any recovery mode

MacBook prollate 15 late 2011.

I was using the laptop while charging and the laptop suddenly automatically shutdown. After open it back, the startup apple screen and login screen appears pixilated and the login field has purple color. After login the screen went from pixilated to normal Grey screen. After that it just stuck at there.

Booting into recovery mode also stuck at Grey screen, also Internet recovery mode, also with USB installer.

Please help and thanks very much before hand

Answer:
Answer:

You detached all external devices?


You saying that internet recovery mode ended before getting to the recovery mode choice screen?


Try a safe boot.

Shutdown your machine. Hold down the shift key. Poweron. The boot up will take longer than normal because the filesystem on the startup drive is being checked and repaired as needed. All about safe mode including what features and apps safe boot leaves out.

I experienced the same problem in that exact model, Macbook pro 15" late 2011, it suddenly turned off, and now when I try to boot in normal / safe / recovery / internet recovery mode it always stuck in a white, grey or purple screen after the Apple loading bar being at 70% full.


I can't access safe mode because I have firmware password configured.(Need recovery mode to remove it)


I thought this was a hardware problem but I could install Ubuntu Linux and it runs correctly, so I don't know what else to do to recover OS X system.

Maybe the various recovery modes do a normal boot. It could be that linux doesn't use the video chip. You would need to try to boot in safe mode, which doesn't use the video chip.


You best take it to an apple store to see what they have to say.
