Power On Mouse won't work after Windows and UEFI upgrade / update

[Turbopuschel]

Hi there, I have a small but annoying problem which I hope you can help me with.

I upgraded my Windows 7 64 bit to Windows 10 a few days ago and upgraded my UEFI and mainboard (ASrock H97 Pro4) drivers on the occasion because there were new versions for Win10.

Until then, I used to be able to power up my computer from shutdown (not sleep, hibernation, standby or anything) by clicking a mouse button; the corresponding setting in the UEFI ("USB Mouse Power On") was set to enabled and it still is.
Now the only way to power on the computer is the power button. I can still wake the computer up from hibernation, sleep etc. via mouse click ("Allow this device to wake the computer" in mouse properties is enabled).

I suspect Windows respectively the Windows upgrade is not to blame because when trying to power up the computer after shutdown Windows is not yet loaded.
But can anyone tell me how I can again use the mouse to power up?

In the meantime I found out that the problem is related to the "Turn on fast startup" setting of Windows 10. If it is deactivated, I can use my USB mouse to power the computer on from shutdown. If it is activated, that does not work. I would like to keep fast startup enabled because that decreases my boot time from 60+ seconds to about 15-20. Does anyone know how to achieve that?

Dear Turbopuschel,

Due to windows 7 of shutdown behavior is enter to s5 state.
But windows 8.1/10 is enter to s4 state, it's didn't fully shutdown the system.
We suggest to enter to Windows10 OS and adjust power saving mode to try.
As windows 8 behavior F&Q:ASRock > Support > FAQ
Then do the BIOS of mouse power on setting for try.
Currently we didn't have this BIOS of mouse power on setting at s4 state.

Thank you.

Thank you for your answer Eddy but as I wrote, I don't want to change the fast startup behaviour because it makes a large difference in my boot time. Does that mean, as long as I want to keep fast startup enabled, there is no possibility of powering on the computer via my USB mouse? And if I understood you correctly, the only way to keep the current startup behaviour and still boot via mouse is if ASRock developes a BIOS update to make that possible in the first place?
