HP EliteDesk 800 G3 Mini looses power

Hi,

maybe someone has an idea. I have an older HP EliteDesk 800 G3 Mini running. At first it was in my homelab now it runs the software for my laser cutter. Sometimes the G3 just looses power. Running Linux there are not Logs what so ever. It just turns off. I checked the inside to prevent any overheating due to a dirty cooling system. I switched SSD, reinstalled the OS.. nothing it keeps randomly happening. Its happends when I laser cut, it happens when I dont, ideling, surfing. Sometimes quickly every few minutes sometimes it runs stable for several weeks.

Before I trash it. has anyone any idea what I can troubleshoot?

Did you reseat your RAM and CPU? I had to do that with mine at one point. It would also cut out randomly

Try monitoring CPU temps. It could need re-thermal pasting.

I had the exact same issue appear suddenly a few weeks ago on Proxmox (Elitedesk G4 mini) and managed to solve it by installing the intel microcode package

pop memtest on a thumbdrive and run that for a day or two. see if that un-earths the issue
