I use my laptop sometimes for field-recordings and 'ondemand' vs 'performance' yields about a factor of 2.5 times more battery time. (here: 90 mins vs 4 hours) - Besides running on battery avoids ground-loop problems. anyway - to come back to the subject: having the "Frequency Scaling Monitor Applet" ask for a password to change the governor would IMHO be the preferable solution. robin _______________________________________________ 64studio-users mailing list [email protected] http://lists.64studio.com/mailman/listinfo/64studio-users
