Hello,
I have encountered a problem, namely this device can not work longer than 1-2 hours. Then the image disappears, the button is lit, but it actually turns off. Only a reboot helps. This happens on Ubuntu and Home assistant and Windows. I can not understand the cause, in the bios did not find anything useful.It turns out that on this device is not possible to run something like HA or something else that should constantly work.
Maybe someone has encountered something like this and was able to fix it?

I just update Bios to 605 version. Nothing changed.

Hello， sorry for that, how about you try to set it up to never go to sleep or hiberation mode and then see if that could work, thanks

Hello again.
Unfortunately, I have not been able to solve the computer reboot problem. I have read many forums and have come to the conclusion that the problem is most likely hardware related and needs to be replaced. Can you tell me how to get a Return Merchandise Authorization(RMA)?
