For those of you who don't know what undervolting is: basically, most processors can run prefectly fine at voltages a little lower than the factory settings. By lowering the running voltage of your processor, your computer stays cooler and your battery life increases.
Here's a good guide for doing it.
So, any of you ever done it? Any comments? Worth the effort? Not worth it? I'm thinking about doing it myself, but it seems like it would cost me a couple days to do it well.

My laptop doesn't really have much in the way of mobo customisation options so I can't do anything there. However I would say that if you wanted to save battery life then you'd have to perform a significant reduction in voltage to make any difference at all. You might get like an extra 10 mins. Probably better to just buy a bigger battery/don't be as heavy with the usage.
Can you say the same thing where overclocking is concerned?
So if I'm doing this, increasing battery life would be the only reason to do it. It's already pretty good (5 hours on a 6 cell battery - thank you Nvidia Optimus), but getting a little more juice out of it never hurts.
Then undervolt it, and run the same test again to see how much difference there is in battery life when the CPU is under full load.

I don't play with volts when over and under clocking but when it comes to Laptops it makes sense to downvolt. Give it a try anyway.
No, but it could reduce the temperature of my CPU further, which means less cooling, and the fan does use a lot of power.
I'm gonna try it when I have the time. Not a very urgent thing.
