I no longer have a desktop computer, but I still have a nice large monitor which is mounted to the wall over my desk. I hook it up to my laptop now and then when I am doing eye intensive work or other large projects.
The last couple of days, the monitor has turned itself on twice, without me even going anywhere NEAR the desk. (It’s not hooked up to anything but the power supply).
Maybe I’ll steal some holy water from the church down the road and sprinkle the monitor with it to see if it melts.
