And, when the periodic wakeups are faster than the refresh time of powertop, no, powertop won't help you find the crapplication. Sorry, miswording: s/faster/less frequent/ I'm not convinced CPU activity LEDs help either, BTW. It only takes the CPU getting crowbarred out of idle for a tiny amount of time before you start impacting battery life, and if the crapplication is only doing it every 30-60 seconds or so, I doubt you'd see it on the LED's.... that sort of thing might be acceptable if you have a 1-3 pound battery, but maybe much less so if you have a bettery which is cell-phoned sized. -- Ted _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
