Everything else is stock. However, after heavy load, or compiling, C-states go to C1 as lowest. I think once they pass the threshold, they don't go back. ThinkPad X220 i5 2520M with integrated Intel video In /etc/sysctl.conf dev.cpu.0.cx_lowest=C3 dev.cpu.1.cx_lowest=C3 dev.cpu.2.cx_lowest=C3 dev.cpu.0.cx_lowest=C3 In /etc/rc.conf powerd_enable="YES" powerd_flags="-a hiadaptive -b adaptive -i 85 -r 60 -p 100" However, once the cores go to C1, they stay there forever, unless I manually set them all back. Any idea on this? -- Lyubomir Grigorov (bgalakazam)
