Hi guys, first of all i apologyze if my english is not good, i’m from Argentina.

I have a Macbook Pro Retina 15 Mid 2012 (i7, 8gb ram, 256ssd, 650m graphic card)

As you can see in this video:


Im having issues with the Macbook.

The laptop turns on, i hear the chime, then the display goes on but nothing else happens, it just stays like that.

it doesn't recognize an external monitor

It happened when i was installing windows in a new partition i created with the disk utility app.


I tried every single solution i found without success, here is a list of what i did:


First of all the macbook does not recognize any boot command at all.

i can’t use the alt option to boot from other disk or device.

i can’t use command r or command alt r or anything to try to enter the recovery mode

i can’t boot using shift to enter the safe mode.

same thing with command s, etc…

it just doesn’t recognize anything.

i drained the battery the hard way without success either

i tried tiping my password...

I tried doing a SMC but nothing happens.

I can do a NVRAM reset, the laptop restarts but nothing happens at all.

i tried all the options with and without the charger, with all the battery and with the battery below 100%


So to resume… i can’t boot in anyway, the laptop doesn’t recognize anything.

it just stays like that.


Please i need help ASAP, anything you need i can make a video and show it to you.


Thanks in advance to all of you!
