documenting won't make it pass or fail the GPU test.
I'm pretty sure this machine was not able to boot up when I sent it in. They ran the replacement without a hitch, but I added a lot of documentation when we sent it in.
Don't know the two are connected, but it can't hurt!
The test runs in firmware at a low level and doesn't require much as far as the computer working. The machine need not boot for it to run, nor do you need to see anything on the display. It boots from a USB drive, and writes a log file with a pass or fail.
