Beat me! (laptop power consumption)

Settings:
- Display off (don't know why backlight still consumes power, any suggestions?)
- wifi blocked via rfkill
- powersave governor
- disabled cpu 123, only 0 active (on the fly)
- hdparm -B 1 -S 1
- vm writeback (60 seconds, stock Slackware)
- disabled fan (loading thinkpad_acpi module via options thinkpad_acpi fan_control=1 (yeah, I cheated :)))

- mounted root with 'relatime' param to reduce disk spin-up

- enabled GPU RC6 mode via kernel params (pcie_aspm=force acpi=noirq i915.i915_enable_rc6=1)

Look at the right to see what laptop I use!
