Hi, I'm new to NetBSD and wonder how I can enable C2 or C3 states to save power? I'm using it on a T420 laptop and observe the cpu stays in C1 despite no workload. Kill-a-watt shows a power draw of 20W. On FreeBSD I was able to see the cpu go into C2 and thus reduce the power draw to 10W. On Linux it can go into C3 and reach 8W.
