Hello,

I have the feeling that my laptop (lenovo y470) consumes much more power under linux that it does under Windows.
The laptop is much warmer and the fans louder under linux, and I don't even use the Nvidia GPU, just the intel IGP.

On Windows the laptop is cold and almost inaudible.

Using the ondemand CPU governor decreases the CPU temperature by 5, which is of course a good start but not enough to keep the laptop cool and quiet.
I have also added pcie_aspm=force to the kernel line in grub.conf

I must admit I'm out of ideas here and therefore ask for your help.

Here are a few commands results and info that might be helpful:

Running Archlinux 64 bits (kernel 3.1.4-1) with KDE 4.7.3
CPU: Intel(R) Core(TM) i5-2410M CPU @ 2.30GHz
