Q: Late 2011 MBP shuts off during OS install
Having some trouble recovering a late-2011 15" MBP. At first I thought it was just a hard drive fault, pulled the drive, tested, dead.
Replaced drive and tried to do an internet recovery, gave an error which was fixed by disabling network security on the wifi. Now it just shows the loading bar and then the screen turns off, holds at a light grey screen, then the whole thing just shuts off completely.
The same thing happens when trying to clean install OS Sierra from USB/DVD.
I've tried clearing the nvram, it stays on longer at the grey screen but eventually shuts off just the same.
Windows 7
