Then maybe this is the reason why I don't notice any particular improvement when I slow down my celeron-m, which uses indeed the P4 modulation sw rather than the speedstep centrino. But then, why slowing down the CPU at all if it doesn't save you any watt? I guess I'll stop using it. Thanks a lot for the preciuos info, Roberto
