I originally started seeing this about a month or two ago. I really only use my framework once weekly to play D&D with some buddies on the weekend. After a couple of missed sessions, I stopped being able to turn the laptop on at all, and started pulling the RAM, SSD, RTC battery, etc. out to see if that would help, and after a bit of tinkering, it would turn back on. Usually after plugging it in to the charger for maybe a minute total. Then it started happening every week that I’d have to do this.
Since speaking with Framework’s support team, and not having a pleasant experience with it, but that is separate, I had left the laptop charging for about a day and a half, and stopped experiencing the issue while they were sending a replacement main board. I haven’t had the issue since, and have occasionally checked the RTC battery voltage. It’s been hovering around 2.8 V pretty much the whole time after.
