Windows 8.1 Only Wakes From Sleep I Push the iMac's Power Button

Hi. Is there a way to make Windows 8.1 wake up from sleep by just pressing the Magic Mouse button or the Apple Wireless keyboard? It will only wake up if I push the power button at the back of the iMac (late 2009). I manually installed all the drivers in the Boot Camp 5 (it will not install if you use the setup.exe for Boot Camp 5).

Thank you in advance. Have a great upcoming sunday mass/great weekend.

God bless,
