Is there a way to do the power tweaks in Linux? I don’t use Windows.
Should be possible. Haven’t tried myself (still waiting for ssd for dual boot).
Try installing msr-tools and then set the register 0x610 to 0x00000000 (power=unlimited). Something like this maybe?:
sudo apt-get install msrtools
sudo modprobe msr
sudo wrmsr -p0 0x610 0x00000000
