Sudden blackouts -- Another reason to use a laptop instead of a desktop pc - and I am considering it. While working last night, I heard a loud boom(!) from the street and the power went out! Waah, the machine! Electricity returned 5 minutes later, maybe less. I was too scared to turn the computer on again right away (and frying something inside ) so I turned the AVR off and waited 15 minutes. It booted up OK, no errors or anything. I did not want to keep it on any longer in fear of another blackout so I just shut it down properly and went away. I did what work I could do on my phone (which was not a lot - last night was not a productive night). What was that noise? It sounded like something blew up.
