Hi guys. I have a problem with a PC, as the title says, it won't stay in sleep mode and I don't know why. I click the sleep option, it looks like it's going to sleep, but it "turns off" for half a second or so, before "resuming". I've checked the bios and there's nothing enabled there that could wake the PC, but, interestingly, the output of "powercfg -lastwake" command shows
Wake History Count - 1 Wake History  Wake Source Count - 1 Wake Source  Type: Device Instance Path: USB\ROOT_HUB\4&e097488&0 Friendly Name: Description: USB Root Hub Manufacturer: (Standard USB Host Controller)
and that thing is the USB port where the mouse is plugged in. In the Power Management tab of the device, the "allow this device to wake the computer" option is not checked and it's greyed out, like on all other USB Root Hub devices there.
The MB chipset drivers are installed, so that's not the issue. Should I get rid of the mouse?
