We have Ubuntu Server running on a NUC6i5SYB that's powered by a UPS. In the BIOS, I have this power option saved:
After Power Failure: Power ON
In the manual, it says this option means: "System will automatically power-on after AC power is restored" :
When I test this manually, by unplugging the power adapter (and plugging it back in), the system does indeed automatically power on as desired.
However, on occasions when the power goes out long enough to completely discharge the UPS, this NUC does NOT power on after power is restored. Other devices, connected to this same UPS, do indeed power on once power is restored.
I believe I'm running the latest BIOS:
Intel v: SYSKLi35.86A.0073.2020.0909.1625 date: 09/09/2020
On multiple occasions now, I've had to drive onsite (late at night) to turn this NUC on manually. I'd appreciate any suggestions that might address this issue once and for all.
