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:
Thanks in advance.
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:as was described in:Code:quiet splash pcie_aspm=force i915.i915_enable_rc6=1 acpi_osi=Linux acpi_backlight=vendor
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:
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
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.
