Recently, I bought a second hand 2017 MacBook Retina 12". After around 2 weeks of use it had turned itself off when I left it running (attached to power) and went away for a little while. The battery had a good charge the last time I saw it (80% - and lasts several hours (80 cycles on the battery)) so it wasn't the battery running down. It wouldn't power on, and when I connected it to power, it got very hot, very quickly.
I took it into a repair shop and they said the logic board was dead. Another repair shop said the same thing.
I searched online, with my understanding being that the 2015 version of the MacBook 12" was the one that had the most issues and that many of those issues were fixed in later models, particularly the 2017 model.
The one of the few things I could find online was that ***a lot of people fried their Mac's (particularly M1s) by using powered PD USB-C hubs (which I was),*** but this was supposedly fixed in Big Sur and I was running Ventura. (I didn't read many forum comments post the date of that Big Sur fix that say they've fried their Mac using a PD USB-C hub. Others such as Louis Rossman says that a lot of the logic boards die on the 12" model.
***I love the weight/form factor of this machine and I'm wondering if its recommended to get the logic board replaced or if this is likely to happen again. Or, is there some other possible cause, and is it preventable?***
Thanks advance so much for your replies.
