Don’t have to screw anything up. I have a machine that has a weird stability issue that I haven’t tracked down - it seems to take out the PCIe bus, so the errors don’t get logged to disk or network - without my KVM I’d have to leave a monitor connected just for this edge case and be home to check on it

Disagree.

They can’t do it through software, but a wireless charger is inducing a current in a coil. NFC chips often use a coil antennal, and inducing a current in that could well trip a protective device, like a resettable fuse. It could be limited to these devices because of a particular resonance or harmonic they share
