The Cartoon History of Iceland, page 14. (Patreon)

   Had a bit of a scare, today. Come home after a busy day, get ready to post on Patreon - and my computer won't turn on. Screen says "No Signal", and the on/off button does nothing, no matter how long I hold it down. In desperation, I check all cables. They're fine. Has malware bricked my computer? In desperation, I do what little I can do: I switch my 'puter's power cable to a different socket.

   ...And THAT worked! I have no idea why. More and more of today's tech is a black box, "No user serviceable parts".
