But, still add i915_enable_rc6=1 and pcie_aspm=force to testing: HP openSUSE 11.4 3.0.4-43.3-desktop i586 kernel (openSUSE:Tumbleweed) battery discharge brightness lowest level wifi off Desktop 3D effect enabled enabled i915.i915_enable_rc6=1 powertop 11.3 boot after 10 minutes: 6.6 W long term: 8.4W AC Plug-in power monitor(removed battery): 10 - 11 W HP openSUSE 11.4 3.0.4-43.3-desktop i586 kernel (openSUSE:Tumbleweed) battery discharge brightness lowest level wifi off Desktop 3D effect enabled enabled i915.i915_enable_rc6=1 pcie_aspm=force powertop 11.3 boot after 10 minutes: 6.7 W long term: 8.3 W AC Plug-in power monitor(removed battery): 9 - 10 W Compare with didn't add parameters: i915_enable_rc6=1 save 1.x W pcie_aspm=force save 0.x W On my machine, the above parameters useful for battery, but didn't have huge improve like Thinkpad X220 with i7. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
