Of course, the most effective way of increasing battery life is the conceptually easiest: lower the power consumption.  Laptop CPUs are usually set at WAY too high of voltage for their clock speeds, so, in a move that's kind of the exact opposite of overclocking, you can undervolt.  My experience is limited to RMClock Utility, of which there are a few decent guides on the internet about using. It sure makes your computer run quieter, too, which was the main reason I set it up for my girlfriend.  Her HP, which runs a 2.2 GHz C2D, uses a maximum of 1.05 volts at full throttle, and .85 volts while browsing the internet...and that more than compensates for screen brightness in terms of power used.

To put it more simply, I get slightly better battery life when the CPU is undervolted and the screen is on maximum brightness than I do when the CPU is running normally, and the screen is on minimum brightness.  Add minimum brightness to that, and I've gained almost an hour in battery life (though she does have a larger battery, so don't expect miracles...20% is probably the maximum, as a decent guess)

 

Here's a decent guide to undervolting your CPU, but it's a little rough around the edges.  I wish MPC would take up the task, really, you guys always make the best guides for everything.

Undervolting definitely works well, but the actual program one uses for said undervolt (if you can't do it throught he BIOS) varies...  and not all work with all processors, hence my hesitance at including CPU-frequency-altering programs on this freeware list...

 This article (the most amazing undervolting guide ever,) I found about a month ago explains all you need to know about undervolting.

 AMD PROCESSOR UNDERVOLTING - http://aspiregemstone.blogspot.com/2009/06/k10stat-amd-griffin-processor.html

 INTEL PROCESSOR UNDERVOLTING - http://www.nordichardware.com/Articles/?skrivelse=465

It does take a little work, but it definitely pays off. My Phenom 720 unlocked gets to 65C on full load at 3.6 ghz, with K10STAT undervolting it idles at 800 Mhz (Plays Hi-Def videos at this speed aswell, No cool n quiet required, it's disabled in my BIOS.) My HP DV5 lappy idles at 1.1 Ghz and has an Intel Core 2 Duo (2.1 Ghz full)

Hope this helps.

I have a HP Compaq Mini 110c-1100CA which runs WinXP Home -- need to find a way to put WinXP Pro on it - and am wondering which ones are good for netbooks?  I already know that Aerofoil would be useless because it's mean for Vista & 7 only.

Ahh...  there is an XP version of one of these tweaking programs, which I omitted from the list because.  Um.  A program that only works on XP isn't very applicable to all...  let me see if I can't find out what that was for you!

My desktop computer runs Vista, but all 5 apps are for netbooks/notebooks, so are useless to me for that reason, however, since I have a netbook as well they are useful to me -- well except Aerofoil -- so that is why I was asking which ones would be good for XP.

On another note, I'd love to find out how to replace WinXP Home with WinXP Pro on the netbook.

...is phenomenal; I am pleasantly surprised with this app.  Out of all the other recommendations, I think this is the only app worth installing and keeping.  You should probably also mention the myriad of other things you can tweak through the program (like changing the color of the windows when the battery level reaches warning and critical levels).

 And as always, great list.

Aw.  Thanks, Mister Mistamine.  You can indeed do a ton of things with BattCursor, so if the lure of changing one's mouse appearance is enough to try the app, all the extra features are like a super-mega bonus.  Or something.

Either way, glad you like the app!

"why let your computer run all night for no reason?"

for Folding?

 

Jokes aside what I'd like is when i say Launch Daz 3d or Champions Online it goes into High Power mode, (since champions is a bit demanding be nice to turn off aero too) for web browsing and word normal balanced mode, when unpluged low power, (when unplugged but running daz/champions go to ballance and give me some kind of "you kicked out the plug again dingu" warning)

Any combo of those do that?

Hmm...  you could do it by shortcut?  But I have yet to find an app that will recognize the program you're running and adjust power settings accordingly...
