Hey Nicolas,

I bought the 7 hours of battery life for windows by:

1. Setting the power plan to "power saver"
2. Dimming the panel to almost the lowest level

On linux:

1. Running kernel 3.1
2. Patching it with the "vaio full 3.0" patch - i believe it's part of 
the sony laptop module as well
3. Installing laptop mode tools and assuring that my CPU never goes 
higher than 800 mhz when on battery
4. Adding the following to grub: pcie_aspm=force i915.i915_enable_rc6=1
5. dimming the display

Hope it can help you in troubleshooting :)
