• Kernel 3.15.1.-1


    Hi,
    I updated the kernel from the latest 14.6(?) but with the new one, my CPU (i5-3210m) doesn’t go to powersave mode.
    My usage is <10% but the CPU’s frequency stays at ~3GHz.

    Don't forget to mark as [SOLVED], if your problem was solved!

  • Try setting to performance, reboot and back to powersave.

    sudo cpupower frequency-set -g performance
    reboot
    sudo cpupower frequency-set -g powersave

    If this doesnt help, disable intel_pstate and enable it back after some kernel updates.

    sudo nano /etc/default/grub

    GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash intel_pstate=disable”

    sudo grub-mkconfig -o /boot/grub/grub.cfg

    Please give a feedback after you get help so the thread can be set to solved.
