Fan not detected is back, although the fan works on its own, without needing to usr fw-fanctrl. I have tried resetting the bios to defaults and resetting the ec, next will try a mainboard reset and force reinstalling the bios. I will take a look to see if there are official instructions for the 13"…

Though not enjoyable, have you tried messing around with the cable and connectors to the fan? It might be a bad sensor on the fan too or the cable has a bad pin. Just a thought to try. Intermittent issues are some of rhe hardest.

Good thought re github - will take a look. I did open a ticket with Support. Fortunately the machine is and has been operating normally other than the alert at boot, so it’s a minor annoyance for now. It will be interesting to find out what the root cause was. I will update here once that has been d…
