Car allergic to vanilla ice cream (2000)
This reminds me of a problem I had a few years ago. Whenever I sat down on my office chair, my monitor turned black for a few seconds.<p>One day I started to understand what’s happening when I touched the aluminum Apple keyboard while being electrically charged. I was wondering how it was possible to get an electric shock since my Mac Mini had no connection to ground via its IEC-60320 C7/C8 connector. I learned that the Mac Mini grounds itself via DVI.<p>Turned out the pressure cylinder of the chair caused some kind of electromagnetic pulse, which interfered with the DVI signal and forced the monitor to resync every time I sat down.
