    Exclamation 13.04 baterry live mode 1.5 hours! "nube" question...

    Hi! I`m new to ubuntu, and not so good in English as could be, so sorry about that...

    I bought a new laptop (Dell Inspiron 15r also known as 5520).
    It was sold with ubuntu 11.04, but i wished to use a newest ubuntu, so i installed 13.04 (also managed partitions better for my self)...

    And after install as a week i`m using it with 1.5 hours from unplugged charger (mean battery live mode if it calls so...) instead of 4-5 hours as Dell company says.

    So i started to search, and i`m confused with results....

    What packages i need to install, or what lines of configuration i need to change to fix that?

    This Ubuntu is more configured for work, i`m a web developer, so for web testing i`m using virtual machines on Virtual Box (test all versions of IE, and also use photoshop there to, gimp does not supports photoshop text layers), i wrote this cause maybe it can be necessarily to choose packages and required things to do,

    Currently in this question i`v tried to do as described here:
    http://askubuntu.com/a/258188

    Thanks in advance.

    ----------------------UPDATE---------------------
    Current state of my google searches are:

    1 - I installed bumblebee as sad here: http://askubuntu.com/a/258188 and that made my laptop to make more noise as was before (now i can listed the cpu cooler works perhaps the video card cooler, before it was almost without any noise i want to remove this noise, should i remove bumblebee?).

    2 - Also i`v changed grub kernel parameters options to:
    Code:
    quiet splash pcie_aspm=force i915.i915_enable_rc6=1 acpi_osi=Linux acpi_backlight=vendor
    as was described in:
    http://askubuntu.com/a/93661 - first i used this
    http://askubuntu.com/a/93668 - than do as says here and the final result of options i writed above
    i used grub-customizer which i installed as sad here: http://askubuntu.com/questions/10023...rub-boot-order which is the same as on official resource when adding ppa repository

    3 - i also installed cpufrequtils and used this links:
    http://www.linux-magazine.com/Online...h-cpufrequtils
    http://www.thinkwiki.org/wiki/How_to_use_cpufrequtils
    to make the same operations for more battery hours for me

    4 - installed powertop as sad here http://askubuntu.com/a/408

    What i can do more i found:
    1 - http://askubuntu.com/a/258187 and http://askubuntu.com/a/2703 says to install jupiter
    2 - here http://askubuntu.com/a/174834 i stoped on https://wiki.ubuntu.com/Kernel/Power...erSavingTweaks and dont know which config to use...
    3 - http://askubuntu.com/a/93658 this is telling me about laptop mode tools, but comment under claims that some issue will create mouse cutting out when on battery issue

    and i dont what to do like that
    http://askubuntu.com/a/1556
    guy, to enter every time what services and pogram to kill/stop to have 8 hours of work.

    I nead to have 4-5 hours as was described in review about my laptop, not 1-1.5 hours as it is now.... Currently i chargin full battry will see again what changed, and after write down here status update.

    Exclamation Mad about graphics and power management

    Hi!

    I bought a new pc, Dell inspiron N5520 i7 with AMD card (AMD Radeon HD 7670M 1024МБ GDDR3 discrete).
    I removed an 11.04 ubuntu from there, and installed 13.04 (and i`m thinking that this was my mistake...)

    So the first thing, i couldn`t install a driver for it. The fglrx* gives tertible errors to unity.

    Also i have battery capacity 1:39 only! Not even a three hours (on some reviews i heard that this laptop worked even 6 hours, where is 6 and where is 1.5 hours? x4 time deifference.)

    Im not well expirienced, and i liked how ubuntu 13.04 works, but this two things are making me mad... I tried to solve them both, nothing!!! Looked for lots of links, and im asking, no, even begging, someone of you to help me with this!!!!

    I tried powertop, laptop-mode-ulitiltes, changed grub configuration no change with battery....

    For graphic card i tried also lots of thing, and only received an errors.

    So please advice me, and lead me to solution. Don`t know what to do with those two question. Im starting to think that i must be a linux guru to work on ubuntu....

    thanks in advance..

    You could start by letting us know what the errors are.

    Talking Re: Mad about graphics and power management

    After my post i`v watched again, and prepeared for some console work using recomendations from:
    http://ubuntuforums.org/showthread.php?t=1930450
    and i remember that better solution was listed here:
    http://askubuntu.com/a/288355

    So now seems that graphics are properly installed! Yey!!!

    But why when i "System Preferences -> Details" i see, graphics "Unknown" <- this after
    Code:
    sudo aticonfig --px-dgpu
    update: when i rebooted the pc, it writed "AMD Radeon HD 7600M Series"

    and i see "Intel® Ivybridge Mobile" after:
    Code:
    sudo aticonfig --px-igpu
    this one i understand, couse it says in console:
    PowerXpress: Integrated GPU is selected (Power-Saving mode)

    So i think that this question is solved.

    But what about powermanagment? Where i must look for errors, or logs that can help with issue?

    Are you still getting terrible battery life even if you just use the Intel GPU?

    Re: Mad about graphics and power management

    Now laptop says near 3 hours of battery life its a good news... the proper video driver made it better.
    Besides battery capacity jumps (3:03 after moment 3:10 then 3:01 and 3:04 and so on). think that this will stabilize after some time of laptop use...

    So how to make it to 5 or even 6 hours?

    i mean first check if all driver are proper, guess that can help also. But how to do it? Check if driver normal, and replace it with normal one.
    Also there are some tools like powertop (installed), laptop-mode-ulitiltes (installed), jupiter (not installed) and some config tweeks that can help...
    I had also bumblebee, but figured out that this one only for NVidia cards so i removed bumblebee*.

    In grub kernel parameter is:
    Code:
    quiet splash pcie_aspm=force i915.i915_enable_rc6=1 acpi_osi=Linux acpi_backlight=vendor
    Graphic card currently is in Discrete mode by command:
    Code:
    sudo aticonfig --px-dgpu
    What i can do more for this?

    You shouldn't expect 5 or 6 hours (especially with the discrete GPU). Manufacturers always exaggerate battery life and Windows seems to have better power management.

    I had similar issue - 1:30 battery. Manufacturer said 6h of battery, Windows 8 does 5h. I installed GPU (bumblebee and primus - I have nVidia), Powertop tunable set on boot, Jupiter is discontinued so I used TLP:
    Code:
    sudo add-apt-repository ppa:linrunner/tlp
    sudo apt-get update
    sudo apt-get install tlp tlp-rdw
    sudo tlp start
    now I get 4:30 battery... which I think is quite good...

    Also, the screen brightness is very important regarding battery life...

    Hope it helps...
