Has anyone with the same symptoms taken the board out and looked at the other side??

There is a shorted cap c6701.

Unsure what it's values could be, but I will try to trace it to the nearest connected IC and look up a datasheet to hopefully identify a suitable replacement value

cheers​

Thanks for the reply; Unfortunately I just tried only replacing the first instance of $SVS from the bin, verifying every read and flash along the way with md5sum. Still, no signs of life on the laptop or charger

Greetings! I got a 17" Macbook Pro that I tried resetting the EFI password on. The computer still turned on and charged.

I was able to read and verify three dumps from the EFI chip, then I modified it removing the two $SVS sections and flashed it to the chip successfully.

Now the laptop won't show any lights on the charger, or the battery status lights, and nothing happens when I try to turn it on.

I did not remove the EFI chip from the board when doing my work. I followed this guide: [URL="https://gist.github.com/willzhang05/e5b5563cdc65514dfb7ca131e03ca4b2"]Mac...
