While plugged in and browsing the web, my assumed trusty MacBook Pro flicked off, never to turn on again... It's a sad day. Luckily, Louis Rossmann has many videos on these models, and I tracked one down that may help me. I pulled the board out, checked the rails, and it seems that I'm not getting output voltage on the TI TPS51980A power controller IC. Both input and trigger voltage are present. It seems that the chip has failed.

I'm checking around online some more and may have to do some more diagnosing for any bigger issues, but I will be needing to replace the chip at the very least. I guess it's time for a rework station. :P
