I recently bought a desktop PC, and I've noticed something weird happening. Whenever the PC is in sleep mode and I plug another device somewhere in the room, the PC wakes from sleep on its own. I have my MacBook Pro on the same desk, and today I was doing iPhone backups - just plugging the iPhone cable in the MacBook Pro USB port (via a dongle), made the PC wake up from sleep mode, even though there's nothing connecting the 2 machines. Even plugging a mouse or any other device (External drive, iPhone cable, MacBook Pro charging cable, etc...) produces the same effect (even things that have a very low power consumption).
I did a few tests and made sure not moving the PC mouse or keyboard accidentally - so these are not responsible for waking up the computer, it's clearly due to other separate devices.
I'm not sure what to do, and I'm not familiar at all with Windows (this is my first Windows machine) and electrical stuff in general. Has anyone already experimented the same problem, and if yes is there a solution? Thanks!
