    Create a simple service file, say /etc/systemd/system/powertop.service:

    Code:
    [Unit]
    Description=PowerTop
    
    [Service]
    Type=oneshot
    RemainAfterExit=yes
    ExecStart=/usr/sbin/powertop --auto-tune
    
    [Install]
    WantedBy=multi-user.target
    To enable it at boot:
    $ systemctl enable powertop
    Thanks.

    1) Don't use LaptopModeTools, its pretty much been abandoned. Everyone's moving/moved over to TLP.
    2) You're supposed to be TLP + PowerTop together, not just one or the other.

    you also need to add the following line to the [service] section, as powertop appearently needs a terminal to run:

    Code:
    Environment="TERM=xterm"

    This is one of those things which I think should be included in Ubuntu, all the work done behind the scenes with a toggle in the Settings between performance states.

    I don't need to install a Power Manager in Windows or Mac to get optimisation.

    Well, ok, but comparing it with stock Ubuntu is not that useful, it would be more useful to compare it to the "fire and forget" methods like laptopmode settings.

    best power monitor

    i did able to get idle watt around 8.5-9.5 W, and on movie playback around 13-14W(with 3.14 kernel on i7-3630qm), turn everything in powertop does not always saves power, i still follow the power-saving guide from archlinux.
