Adam, Which method are you using to measure power consumption. If you've got a Nehalem-based laptop, you can use turbostat to verify the hardware C-state residency: http://userweb.kernel.org/~lenb/acpi/utils/pmtools-latest/turbostat/ cheers, Len Brown, Intel Open Source Technology Center _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
