Commenting to +1 this issue. My intended use for my laptop was intermittent usage: I prefer to perform the majority of my work from my desktop; every few weeks having the need to be mobile. Every time I have pulled out the framework it has failed to boot unless plugged in to AC - very frustrating.
I love the principles and build quality of this product and company, but having such a major flaw (2-3 weeks max on standby), not being upfront about that [seemingly known] restriction, and no official response makes this is a deal breaker. I will be recommending against framework until this is addressed.
P.S. - yes I am on 3.0.7, have attempted resets described above, etc.; hasn’t helped. Really seeming that we need a “hardware patch”, new board.
