I just installed BIOS 3.07 about three weeks ago and since then I’ve run across a very weird issue. My Framework (1st batch) won’t start up any more when I’m not plugged into power. I can press the power button once or hold it down for a while, and get no response whatsoever. As soon as I plug in the power cable and the side LED lights up, pressing the power button starts the boot cycle as expected. If I disconnect the power afterwards the laptop stays on with no issues. I can even shut down and restart after disconnecting from power for a little while afterwards (I only tested up to 10 minutes after shutting down and I could still start up on battery only at that point) but eventually I have to plug back in again to get it to start.
Anybody else see anything like this?
