Question Asus prime x470 won't power manage (no sleep or hiber)

[cbeatie]

I recently built a new Ryzen setup on the Prime x470 motherboard. I'm running win10 and the machine won't sleep or hibernate. I've enabled ErP in the BIOS for s4 and s5. Everytime I attempt to sleep the machine it powers down for a moment then comes right back up. Ideas?

You might have the PC to wake from things like LAN or mouse (especially a Bluetooth one).

Go into your device manager, click on LAN, click power, and then I have mine set to "only wake from magic packet". Go to mouse, and disable it being able to wake the PC.

Unplug your peripheral devices and network interfaces one by one and see which one wakes your PC. I'd even start with unplugging all of them aside from your monitor. If that's not enough then update your BIOS and load optimized defaults. If this doesn't help as well, I've no idea. Perhaps you've got a faulty BIOS.

You can also use the "last wake" command, and most of the time it will tell you which device brought the item out sleep: https://www.howtogeek.com/122954/how-to-prevent-your-computer-from-waking-up-accidentally/

Just from my experience it's always been my wireless mouse or network adapter.

powercfg -lastwake

Good command to see what's causing the wake.
