Some have a real power switch at the back near the power plug. I got recently a notebook with a Transmeta CPU in it. It runs some 9 hours on some 60W. I also miss real desktop machines with this kind of CPUs. They have enough computing power for most needs. You might wait for Sun's blades with Mobile Athlons. Do you know if FreeBSD 5.2 runs on a Transmeta CPU with support of the power options? My notebook is the Fujitsu P2120. Erich
