A few days ago I changed the APM Configuration > Power On By PS/2 Keyboard setting in order to have the system powered up by the CTRL+Esc key combination.
However nothing seemed to happen: the system powered up just pressing ANY keyboard key.
Not a big issue, obviously. I thought that maybe there was a little, essentially harmless, mistake in the UEFI UI or in the software.
So I was quite surprised when this morning, after many power on/off cycles in the past days, the above mentioned setting started to actually work: the system now powers up "By Keyboard" only if I press the CTRL+Esc combination.
Is such a behaviour normal?
If yes, shall I expect it also for other UEFI settings?
