Having failed to get hibernation working (see recent posts about Secure Boot getting in the way), I tried to fall back to suspending the system overnight. That works of course.
What doesn't work is waking it up automatically. If the RTC can wake the system from hibernation, why can't it wake it from suspension? I don't want to have to be in front of the system to wake it up.
Sigh. Turns out the UEFI had *another* setting aside from enabling wakeup. You have to tell it that the RTC alarm is controlled by the OS and not the BIOS.
It's working now.
