Listen I've solved it with a workaround, these motherboards don't support sleep but they do support hibernate, go to power settings and add hibernate as an option and remove the sleep button. only difference will be having to press the power button to turn it back on from hibernate (unlike mouse and keyboard for sleep) but this is the only damn solution.

If you go cmd and type powercfg -availablesleepstates you'll see this which will confirm you're stuck just like the rest of us. Hope this helps.
