Thinkpad X61s and power consumption
-
Managed to drop my laptop’s idle power consumption to under 9.5W with a few keystrokes. I love Unix.

I’m seriously thinking about getting a X61s off of eBay soon. What keystrokes did you use? :)
Could you share that information. Maybe it could be helpful to the bunch of X61s users out here ;-)
I’m not impressed by this. I am assuming you’re using powertop to see whats using what and you’re killing/disabling processes accordingly. When I had my Thinkpad X300, I couldn’t get it below 11W running on X11 with Wifi. If you got 9.5W I’m guessing you had Wifi off.
That of course meant about 2 hours battery life on a 6-cell battery, while on the same configuration Vista achieved remarkably (for windows!) 3+ hrs.
The ultimate and the king of battery life Unix-derivative is Mac OS X, and you don’t even need keystrokes to get it :-).
As usual, the amazingly rich Thinkpad Wiki has a multitude of information on the topic. Take a look at the article about Reducing power consumption and some reports on idle consumptions by other users.
The simple keystrokes were more or less the tips Powertop was giving on the screen. Also useful are the tips on their webpage.
The 9.5W achieved was with wireless off and screen brightness to almost lowest.
