Intel Nuc i3 11th abrupt shutdown

[harleydica]

Intel NUC i3-1115G4 I installed Proxmox for my home server, but why my Intel nuc often turns itself off suddenly, when I check the syslog there is no indication of damage to the system, I suspect the power adapter, is there any other advice?
Here I attach the last syslog capture before this Intel nuc died on its own
Thank you.

Support for the former Intel range of NUC devices is now provided by ASUS.

Your NUC would seem to be a NUC11TNKI3 - i3-1115G4. It's possible that the issue you are having might be solved by a BIOS update or a driver update. The ASUS BIOS & Firmware support page can be found here .

If that does not work then you could contact ASUS support directly about this issue, see the link on this page .

The bios code does not match my intel nuc, in the current bios it is PATGL357, I looked for it on the intel website but did not find it, do you know?

PATGL357 is the name of the BIOS fitted to the 11th gen NUCs, the version number is something else. ASUS are listing a BIOS Update 0057 for NUC11PKHx / NUC11PAKx / NUC11PAQx series NUCs at this location. There is a  BIOS: README file that is referenced and this seems to indicate that updating to the latest BIOS is possible. However I think you would be best to contact ASUS support and ask them for their advice as to what to do about a BIOS update.
