This morning I came to the lab and turned on the new Linux server that I have been playing with over the last few days. Well, hang on, lets go back a bit: first I turned on the UPS (Uninterruptible Power Supply — something very necessary here in the land of blackouts and spikes), the monitor was still switched on, so it came on immediately. I knew this because of the buzzing noise it made and the small plume of white smoke that rose from near the switch. But what I saw was the power LED on by the switch, so I turned on the system unit. Maybe it was just an insect that got near the electrical gubbins. When the system unit comes on, the monitor switches from stand-by to ON and, of course, the smoke switches from whispy and white to thick and black. I turned the UPS off again!
