Windows 10 power problems

Dear all,

I have an ASUS UX303ln with a clean install of Windows 10 in UEFI boot mode. It seems that:

• when I turn off the computer it turns off the screen and fans, but stays on, consuming an unusual amount of energy (in about 30% of the cases it actually turns off properly)
• When I hibernate the computer, same thing happens
• When I put it to sleep, in about 60-75% of the cases it won't wake up, instead it will just enter this high power mode with screen off, mentioned in the first bullet point

These issues persist, even after turning off hybrid sleep, fast startup, hibernation, changing over to CSM boot, trying to downgrade/update drivers for Intel Bluetooth (which sometimes was stopped by windows due to not being Windows 10 compatible), the Management Interface, and Intel and Nvidia drivers.

Try as I might, I can't get rid of this problem. I'd be glad if somebody could suggest anything that might prove to solve this.

Thank you in advance.
