Just another data point, I got a Beelink S13 Pro N150 running similar things as OP and haven't had any issues. I made changes in BIOS (set "Chipset > PCH-IO > State After G3" to S0 so it boots up again after regaining power) and they are sticking for me.

Same here, N150, no issues. Don't think I've made any changes to the BIOS.

Fans spin a lot near-constantly though, I think it is the on board M.2 SSD that is hot, I need to get around to adding a thermal pad or something one of these days.
