Late last year my machine would shut off whenever the discrete graphic card fired up. It got bad enough that I couldn't even reinstall the OS after wiping it before dropping it at the repair shop. Had to literally stick it in the freezer to get through the OS reinstall. Cost ~$430.
Apple came out last month with the extended repair program for this problem and after a couple calls I managed to get them to refund me the repair costs.
Now I'm getting the logic board replaced again. Slightly different symptoms this time. When running something that invokes the discrete GPU (chrome, a game, etc) it'll randomly shut off or sleep at anywhere between 40-70% battery life and won't come back on unless I plug it in, at which time it still shows 40-70% battery life and continues working on battery if I kill the app using the discrete GPU. Also, when I'm using Safari and not the discrete GPU, it'll randomly lock up for about 15-20 seconds, then reboot.
Local repair shop ran their hardware test and got a VST error. They've ordered a logic board for me, under warranty, and I'll have to take it in to swap it when the part arrives.
I no longer have any confidence in this machine or Apple's ability to produce a logic board for it that will last for any meaningful amount of time. Very much looking forward to the Skylake machines coming out so I can upgrade.
