NUC7i7DNBE Random restarts with power supplies over ~16v

[Russell]

I've had a random restarting issue (no errors and totally random) with the NUC I have pretty much since I got it. I replaced the power supply (20v) which came with it and the issue went away.

I have however discovered that the power supply was working fine all along. The replacement power supply I bought was 15v and it looks like anything over 18v causes my NUC to randomly restart.

I can work around the issue by simply never using a power supply over 15v but something is definitely not right so I thought I'd post this finding.

System:

NUC7i7DNBE

Ubuntu 18.04.4, kernel 4.15

120GB Corsair Force MP500 M.2

8GB (2x4GB) Corsair DDR4 SODIMM Value Select, PC4-17000 (2133)
