I turn on my PC. The monitor sits happily on standby. Hmm. Try again, same result. Windows is booting, since the Sleep button does as it’s told. Third time lucky, but Windows has apparently mislaid my monitor drivers. Oh well, quick reinstall of those and all is well.
While this was going on, my door buzzes. It’s a Jehovah’s Witness (the first one I’ve encountered in years).
Coincidence? You decide!
