Interesting read for laptop owners

Discusses undervolting ones laptop to prolong battery life and reduce heat output.
Somewhere in the area of approximately 20% less battery used after this was done.
Works best for laptops with throttle processors.

going to give it a try with mine tonight, since I've got a power hog, as well as a portable space heater.

wasnt that the whole idea behind the Pentium M?

Umm...for cons he lists nothing? How about loss of system performance...If you are multitasking on and undervolted laptop you are going to notice much longer screen load times and what not...And that annoys the shit out of me. If you are looking for longer battery life just get another battery. If you are thinking of preserving your laptop it will be out of date before it is worn out. How could he not list ANY cons? Retard...You know somone is going to do this and wonder why photoshop CS takes so long to open....or acrobat...or any other processor/ram intensive application...even playing a dvd could be affected...

Yeah, pretty much.
Even though those things have a bad habit of throttling up to their highest mhz speed for doing the most mundane tasks like opening a browser window, ect.

I'm not sure there'd be performance loss. He mentioned just undervolting, not underclocking it. I think there's a designated speed setter for certain programs, too.
Also, the author said it was his 4th computer, much like myself, and probably does system intensive computing from a main rig, that's overclocked or beefed.
I definitely don't think playing a dvd would be be impacted too, as long as the throttling doesn't take it down to 100mhz or something. I'd like to try this out for that reason in particular. I mostly use mine for flicks and the occasional game of fear on the road. If I can squeeze another 25 minutes out of my movie viewing.. I'm into it.

I'm interested, but I feel this project is a little above my personal understanding of computers, especially my laptop.

[Deadbent]

Yo Moe.
It's not really too tough, but the only thing greasy about it is that you need a bit of understanding with what sort of power consumption your cpu has, and setting the throttled frequencies in accordance with that.

If you want to squeeze a few more minutes out of your lappy, shoot me the specs, I can give you a rough guideline on what to do.
