    Phoronix: Other Ways To Optimize Your Linux Battery Life

    After writing recently about the PowerTOP 2.6 release and mentioning that some new power consumption/efficiency tests were in the works at Phoronix, a few readers wrote in asking about other ways to extend their battery life under Linux...

    As I wrote here we have the result in idle mode = machine "nothing" does not and has blanked the screen - this is a screenshot after the activation. During normal operation, such as active: Chrome, LibreOffice, console, etc., gets about 5-7 watts - this in my series of kernels Premium - here i7-pro - Dedicated for Intel Haswell family. Similarly X370 - AMD APU E-350 in idle mode from 3.8 to 4.5 Watt, and from 5.90 to 7 watts during eg typing text into LibreOffice or viewing pages on which there is little flash.

    LMT is deprecated. TLP is the way to go. And its automatic.

    @savvys
    There's a ton of possible tweaks. Which are NOT implemented by TLP?
    When TLP is active Powertop shows no tweaks are enabled. What does it mean? I'm asking because no other scripting tools can be used in parallel to TLP.

    Install laptop-mode-tools

    On the stock ubuntu 12.04 my power usage went from 13watts to 9.5watts.

    Enjoy.

    pervasive powersaving udev rules, throttle script, indicator-powersave

    Last week I got a little manic about powersaving and condensed many sources recommendations into some useful tools.

    All the details are in this post on the archlinux bbs.

    Neither the udev rules, the script, nor the (optional, wip) indicator are archlinux-specific.

    The udev rules use several wildcards and conditionals to effect setting powersaving modes across a large variety of devices with as few individual rules as possible. The script switches powersaving mode on and off at the user's discretion. The strictly optional indicator, which is really just a few patches--available in the AUR--against indicator-cpufreq, provides a
    GUI for the script.

    We invite you to netext73.pl. Home Page for now only in Polish - soon also in English. The program itself will automatically switch to English or French - based on system settings.

    Program and delivered solutions are tailored to Ubuntu and derivatives systems, such as Mint, elemntary, and soon Debian / Steam OS

    The program distributes Netext'73 my solution: kernels, energy management and efficiency scripts - APM, the latest microcode / Linux firmware and the appropriate entries in Grub.

    Installation of these components allows for improvement: productivity, responsiveness, energy efficiency and security.

    With solutions used can achieve the results outlined below:

    Energy - Kubuntu 14.04 - idle mode - Lenovo Yoga 2 Pro:

    640 mW = 0.6 watts - kernel v28.8-i7-pro - other solutions referred to above

    MSI X370 - AMD APU E-350 - Kubuntu 12.10:

    4.01 watt - kernel v26.1-brazos - other solutions referred to above

    4.02 watt - kernel v26.1-brazos - other solutions referred to above

    Under the current kernels is sometimes better

    Responsiveness and efficiency of the system:

    There are many tutorials, google for the Intel compiler name (iasl).

    You can do that also in the kernel config if you bake your own kernels (Gentoo anyone?). There is also timeout values and other options to be set. It spreads a bit though. Some of the options are in the energy management section, some in drivers, some in CPU section of the config.

    PCIe ASPM maybe?

    go there and check
    --> "Linux kernel parameters"


    What about these ACPI tables? I guess the kernel can now handle most of the abominations made by MSFT compilers there but still... is there any good tutorial for beginners how to get that stuff fixed?

    pm tricks

    I found some really easy "tricks" following this link and reading the comments:

    http://crunchbang.org/forums/viewtop...0720%23p110720

    I now copy a number of scripts be run "automagically" every time laptop is on power and using powertop I find only 2 actions that I am recommended following that. One being my wireless I ignore that (as the foss driver I use do not seem to have powersavings anyhow) and the other some setting that does not affect much. Currently my battery easily outlast my UPS that only feeds a wireless router and an outdoor wimax unit
