Dear Experts,

does anyone know how to find out which device is waking up my pc (Windows 11 Pro, 22H2) from sleep mode- Powercfg -last wake tells me it was "Intel usb 3.2 extensible host controller" (see attachment), but does not state the device. Since only my wireless razer mouse or the keyboard have the permission to wake up the pc, I wonder if there is an option to find out which device is responsible without unplugging everything. Ethernet or wake on lan is deactivated already,

Thank you!.

Just an USB upstream cable to the monitor and razer speakers, that‘s it. I do not assume those cause the issue (?)

You can not assume anything as crazy as hardware acts these days. The cable to the monitor is for activating USB ports on the monitor, correct? If so, that would be a place to start. You do not happen to have your KB and Mouse plugged into the monitor, do you? If so, plug them into the root hub on the back of your computer. See if your computer wakes unexpectedly. If it still happens disconnect the cable to the monitor and test again. It's doubtful that it's your speakers, but stranger things have happened so if disconnecting the usb cable to the monitor doesn't work, test by disconnecting the speakers.

Yes, I plugged the KB into the monitor. I will follow your advice and plug it into the root hub. If it does not work, I will come back :-)

I identified the speakers to be the cause. Turning off the speakers wakes up the pc for whatever reason....
