Hi all,
I have an early 2011 15" Macbook pro, yes the one with the graphics issue ?. Keeping this one alive has been a real struggle, having Apple "repair" it on three different occasions before they accepted fault...anyways I'm having a new issue that is leaving me scratching my head.
Several years ago I used the info here to bypass the discreet graphic card. All was fine for the longest time, even upgrading through two new macOS (El Capitan -> Sierra -> High Sierra) but recently I'm unable to get it to boot.
Normally on boot the led will turn on, then the screen backlight, I will hear the CD drive kick on, and then the system will come up.
Now only the led will light and nothing else happens, the screen is still black and the CD drive makes no noise. The fans do still turn on.
I've tried booting into:
Other things I've tried is to remove the HD (Samsung SSD) and try to boot and to remove/reseat the ram (Crucial 2X 8GB).
I'm thinking I could try other options like removing the battery, CD drive, USB drive, but I don't know they would even work since I can't even enter any of the other boot modes. ?♂️
My question is, what safety features are implemented that would prevent the mac from starting?
Does it sound like this system is worth recovering?
Any other suggestions would be greatly appreciated and thanks for reading! ?
