There's 2 more things I'd like to try as well to see how much life I can squeeze out of this puppy:
- The Hitachi 7K60 has a low power mode as well, IIRC. Gotta figure out how to activate it.
- the wi-fi card has a power saving mode. If you're surfing wireless, that could make a big dif.
Personally, I'm just waiting for the 35W 3400+ to come out next year... I'm hoping that'll double battery life easily.

I was just looking around a bit on AMD's website, and I had another thought about this. Why bother with a 35W processor? Whats the point? I can underclock the existing 62W 3200+ to 1.8Ghz, the same speed as the 2800+, the current top of the line 35W model. This will only use 33.7W, less than the low power mobile. This also gives me the 1MByte cache instead of the 512K cache of the low power mobiles. On top of that, we know it is supposed to work in this laptop. This gives you the ability to push the system to get the full power of the chip at 2Ghz, when you have a power source and need the extra speed. Or, you can underclock it and get a longer battery life. I also believe that this would push the power requirements down low enough that it should be able to run off the airline 75W power sources.
Unfortunately, AMD doesn't have the power specs on the 3400+ mobile 65W processor up yet, but I would expect that these would likely offer better performance to power ratio than the 3200+ mobile 65W.
Obviously, this is all speculation based on the tech specs of the AMD processor and the Clevo D470k. I make no guarantees that it will work as I suggest, as I have't tested it myself.
