5680 Maximize extend battery life / reduce power consumption

High all. I thought I went to bed, but I must not 'ave.

I know you all want your 5680's screaming all the time, but there are sometimes when I want my power to last. Like when I'm stuck in an airplane for 4 hours. Also, if the fans are loud, I'd just as soon find a way to clock down the system, so the fans won't come on full or whatever.

Are there any known tricks to maximize the battery charge life?

I know there is the Intel Application Accelerator for harddrives, though I haven't checked if it will work on the chipset on the 5680. (I just ordered mine, but like the rest of you seem to be, I am obsessed with it until I get it.)

Are there any utilities out there to imitate anything like "speed stepping" for these systems? I'd like to clock down the cpu and memory when I'm only using it to watch DVD's or browse the web or code.

I'd also like to be able to clock down the fans, maybe this happens automatically already.

Any input is appreciated.

Also, what the hell's up with Windows XP and suspend. I'm currently using a Dell 4150 (It's my third Dell, and I'm super satisfied with Dell, but hey, Dual DDR Ram, Hyperthreading, M10, I have to give it a shot.) And when I had Win2000 on it I could suspend my notebook for the whole weekend and on Monday morning power on and only about 10% power will be gone, but after installing Windows XP sometimes it goes to 0 over night.

Well, the best ways to conserve include:

First, set LCD Brightness as LOW as possible. It may not be as pretty, but it will save you life.

Next, if you can, clock your GFx card down a bit (with the help of RadClocker or powerstrip). Be advised though: If you clock down, your GPU voltage will stay the same. This will mean that the card is getting more voltage than needed, and could suffer damage.

Next, would be to use Window's power saving features. You can set it to turn of the HDD's after a few min; same with the LCD.

Additionally, close any programs you are not using. They will take up power (processing, ram, etc), and will only hurt in the long run.

Avoid screen-savers. Just set your LCD to turn off after 2 min, instead of running a saver.

Obviously, mute the sound (unless you really want it). Additionally, turn off your Wireless devices (also unless you want it).

Avoid USB devices, especially powered ones. Try to stick to the on-board pointing device.


I think that would be a good start...

How hard would it be for Clevo to release a bios with clock setting overridability for memory and processor? Most desktop mo'boards have this now. Then, in addition to that to have a Windows applet to control this would be good. Then to take it a step further, a Windows applet that would do something like Pentium M's do, dynamically excellerate or reduce based on demand. Sure, it wouldn't be as efficient as the embedded functions in the M.

This could be done with a bios update with no hardware mod's, right?

I want my cake and eat it too, and smear it all over my girlfriend's body, too. Oops, I digressed. Sorry

IT could be possible, BUT, here is the problem. Laptops, unlike desktops, are made to only handle limited amounts of heat. IF you introduce the possibility of OCing, them people, who otherwise dont know what they are doing, there could be a great # of dead/damaged laptops.

IN theory, it should be possible. But, i wouldnt expect it...

Spinning the HD or media drives also eats juice. So, if you can, manage your usage to keep these drives from spinning... (eg don't listen to a CD)

ok c'mon. You guys r tellin him to take all the usefullness out of the laptop. CLock everything way down, dont use the hard drive or optical drive, darken the screen as much as possible and use the power feature to shut it off.

Ok, saving power is always a concern, but then why would you want your laptop if you have everything clocked down. Also, if the gpu always uses the same voltage clocking it down wont do anything. Anyway, best power saving feature, DONT RUN THE LAPTOP. I understand waning to prolong battery life but its not really life if thats what you do with it. A good joke to prove a similar point:


I recently picked a new primary care physician. After two visits and exhaustive lab tests, he said I was doing "fairly well" for my age. A little concerned about that comment, I couldn't resist asking him, "Do you think I'll live to be 80?" He asked,"Well, do you smoke tobacco or drink beer?" "Oh no," I replied. "I've never done either." Then he asked, "Do you eat rib-eye steaks and barbequed ribs? "I said "No, I've heard that all red meat is very unhealthy!" "Do you spend a lot of time in the sun, like playing golf?" "No, I don't". He said, "Do you gamble, drive fast cars, or fool around with sexy women?" "No," I said. "I've never done any of those things." He looked at me and said, "Then why do you give a **** if you live to be 80"?

Huh? He asked us how to save power. I gave him suggestions. He doesnt have to use any of em, not would he have to use them all at the same time...

Oh, I will use all the suggestions, thanks. One of the first things I'll be doing is trying them all out separately to see what works. I'll report all my findings.

Oh, sure, when I am gaming and programming, I will be running full speed, but when I'm flying I like to watch movies or read. Clocking things down, if possible would not affect those things. Plus I'd like to see if can keep the thing from getting to hot on my lap and fans blaring. It is a laptop, right? If I can, I'd like to see what battery performance can be gained.

We'll see. Keep the suggestions coming. Keep the opposition coming, too. It won't affect me, but it might help someone else make a decision.
