Ever since the Creators Fall Update to Windows 10 I have had an issue with my screen not sleeping correctly. It would sleep after the set time but then wake up randomly for no apparent reason. Although it wasn’t a show stopper it was annoying and I spent a lot of time trying to sort it out. Different keyboard and mouse, different keyboard/mouse USB port, move devices to different USB ports etc etc. Nothing I tried worked.

Because it only started after the Fall update I thought it must be a Windows 10 or a driver issue. Which I guess might be true because in the end it turned out to be my USB joystick. It’s an old Black Widow Speed Link which I use for flight simulators. Unplug that and the problems go away. I couldn’t find a driver update for it and as it’s so old I don’t suppose I will – so now it stays unplugged until I need it.
