Thanks. That's the version I use. # cat /proc/version_signature Ubuntu 3.2.0-8.14-generic 3.2.0
It appears adding these options to /etc/default/grub solved the problem (back to 9-10W consumption): GRUB_CMDLINE_LINUX_DEFAULT="quiet pcie_aspm=force acpi=noirq i915.i915_enable_rc6=1" For readers, run `update-grub' after that. I suppose the most important options are "pcie_aspm=force acpi=noirq i915.i915_enable_rc6=1". Note: these options were not necessary in version 3.2.0-7 to have a better power management. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/913886 Title: Power consumption regression (12.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/913886/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
