I had some heat issues and added more thermal pads to my Ne05 NVMe case.
(I have the piHut 27W PSU)
several times I came back to the machine to find an ORANGE light (not red or green)
and the system dead. It required a long press to get a red light, then it powered up again.
Thinking this might be an issue relating to the thermal pad (esp. static) I yet again opened the case and trimmed the pads to ensure none could touch any pins.
Powered up, ran a few test, then deliberately touched my forefinger to the front of the case (beside the button) …the light again turned orange and the system halted
[ I think there may have been a click from inside the case …but I could have imagined this as I saw the light change).
(I think the orange may be red+green LEDs?)
