I contacted support about the “Dead battery on powered off laptop, won’t turn on without being plugged in, battery missing in OS” issue.
The resolution was the BIOS reset procedure (popping the coin cell, disconnecting main battery, waiting 5 minutes, etc). Support asked me to install Windows afterwards to test if it happens again. 
Framework, you gotta fix support responses like that. If a powered off laptop has a battery drain issue where it won’t power on after a week of being idle, and requires a BIOS reset to fix it… it isn’t an OS issue. Your Linux support needs to improve. You don’t have to directly support Linux per-say, but don’t give answers to Linux users that include “installing Windows”. That’s a Dell-style response and won’t distinguish you in the market.
