I ordered the base model 15" touchbar MBP on launch day back in October (2.6GHz processor; only upgrade was to 512GB SSD). My computer also happens to be one of the ones suffering from the strange electronic popping noise on the keyboard. I never looked into addressing that problem, because it was so minor and rare. Two days ago, I was working on it, it was plugged in and had been plugged in and charging for about an hour ... when suddenly WITHOUT WARNING it powered off. I was able to get it to boot up once after that, and it said the battery was at 1% and that the battery was not charging. After a few seconds, it powered down again and never came back to life. I took it to my nearest Apple store / Genius bar ... and they couldn't do a thing for it. They indicated that it seemed as if the logic board was no longer passing power. They said it needed to be sent off for repair. Well, I can't go without my computer and I was panicked for a few minutes ... but after checking with "leadership" at the store, the tech I was working with agreed that they would take the computer back, give me credit for it, and sell me a new one. Unfortunately for me, my latest Time Machine backup was from February. I've been slowly transitioning to Dropbox for Business for my work stuff, so that helped a bit. TL;DR: Backup your computer now. You never know when it might die.
