Definitely solved it!!! Awesome, BTW, check out my C3 time: # gnu-watch -n1 'sysctl dev.cpu | grep cx_usage' Every 1.0s: sysctl dev.cpu | grep cx_usage Wed Sep 1 17:56:31 2010 dev.cpu.0.cx_usage: 0.00% 0.03% 99.96% last 7159us dev.cpu.1.cx_usage: 0.00% 0.00% 100.00% last 6343us I've now seen my computer at it's lowest battery drain rate yet (around 11000 mW) while "using" my system. This just keeps getting better and better mav@, hope we see more testers soon :) -Brandon _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
