Fast-startup and keyboard boot

Normally I would use the sleep button or a shortcut(shutdown -s -t) to turn the desktop off. Lately though ive been using the Start button and shutting down and i've noticed that all it takes for me to turn on the computer is to hit any key.

Now I know that Windows 10 uses a form of hibernation when shutting down but this is akin to sleep mode where any key wakes it up.

My question is whether this is a Win10 thing or more of the desktops(Asus) UEFI thing?

Not hating it, just never noticed it.

The fast startup and hibernation can be modified to your preference.
The event logs may display problems with the settings and should be checked.

Windows Fast startup and hibernation work in tandem with the UEFI (Power states).
