That's the same for the 2017 model that I had to fix. I got a new mobo + battery. Convenient because my battery was in dire need to servicing.

I heard it would take weeks and even had a backup laptop ready, so it surprised me when it came <2 days later. It was my original laptop too (had all my data and the same dent).

Oh well, the new models don't have this issue anymore. What a fuck up.
