I was having issues with my laptop randomly rebooting without any indication what could have caused this.
So when troubleshooting, I tried to reset the bios. Upon disconnecting the battery, I noticed the connector unplugged without me even trying to pull on it. Apparently the rightmost pin was bent preventing the connector from fully inserting.
I never touched the connector during assembly, so I think it’s a factory issue. If someone from Framework reads this, there could perhaps be an extra check during assembly that the connector is fully inserted? (It’s quite clearly visible when it’s fully inserted if you know what it should look like).
Btw, in many images of the guides, the connector is also not fully plugged in. E.g here and here. It should be like this. You can see the white nubs in the metal slits.
