This has been going on for 12 days now. Can't find anything in fora and Acer phone support is worthless.
About once a day, instead of waking up, my Chromebook CB515-1HT says it has been updated, and goes through the whole initial process of selecting a network, entering network password, and logging in with 2-step verification. Once in, the only setting I have lost is my wallpaper. All other settings are retained. The OS version has been 63.0.3239.140 the whole time.
First Acer tech had me try powerwash, but that did not stop this problem.
Second Acer tech told me that this was not a problem with my Chromebook, but with my Gmail, and that Acer could not help with this! Then I remembered that this started about the same time Google security suggested I delete an app-specific password that turned out to be needed for Google's SMTP servers to send mail from my personal domain (even though it is hosted by Google). So, yesterday I tried resetting that password, then doing a power wash, but the problem still did not resolve. (Note: I log in to my Chromebook with my gmail address, not my personal domain email.)
What are the chances of a recovery fixing this? Or is it really triggered by that SMTP thing?
I am trying this forum as well as Google's Chromebook forum because, while I am going to try what has been suggested below, I don't have much hope it will work:
