i'm running ubuntu 11.10 and i'm interested in getting more life out of my battery,
I see a lot of people adding extra lines to their /etc/default/grub file after "quiet splash".
For instance one user suggested
change GRUB_CMDLINE_LINUX_DEFAULT to be: GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash pcie_aspm=force acpi_osi=Linux i915.i915_enable_rc6=1″
This was for his Acer Aspire Timelinex AS4830tg-6450,
The hardware of the 4830TG differ only by the processor, his is the intel core i5-2430M 2.3Ghz while mine is the intel core i5-2410M 2.3Ghz
Are these changes model/hardware specific.
What changes should i make to get the same results (he noticed a big increase in battery life)
anything else i can do?
