Nine-hour Battery Life on a Laptop!

I have a friend who was struggling to maximize his laptop battery lifespan. The old battery used to give him 2-3 hours of computing time. The battery degraded so much through the years that he ended up getting only around 30 minutes of computing time.
The joke is: he’s running on wireless internet but still needs to lug around a power adaptor and get wired to a power outlet.
So he tweaked his system, reduced processor speed, terminated un-necessary programs, changed monitor settings, changed power settings just so that he could make the most of the little juice that his old battery had.
Recently, he got a battery replacement and the battery was more superior than his old battery, purported to provide up to 4.5-6 hours. But now with his new extended battery and his optimized system, he’s getting 9 hours (!) of computing time!
What we do to get un-wired.
I should copy some of his settings.

How did he do all those? Maybe I can do the same to my aging Spidy.

Is he running on Cetrino or the Celeron? It makes a lot of difference.

9 hours unthethered to the brick wall, including wireless? wow!
must be the 9 cell type extended battery, ibm has such for its laptops. although curious what he does to make it extend for that long. as even those 9 cell would normally just fall along 6 to 7 hrs with wireless on and 5 hrs average if you are doing some programming.
on the recent cebit yata, there was a prototype of fuel cells already. wonder how that would perform on actual usage.

I certainly need those settings. I am getting below the 2 hours mark.

I think we should document that, that could possibly a local record.

anybody have a Ripley’s or Guiness contact?
I’ll vouch, one whole working day with WiFi on half the time, zero power outlet time.

In 2004 I bought an Asus M3N, with a built in battery which was in the 4-5 hour (audio + wireless) range. I bought a second battery, which would sit into the hot-swappable optical drive bay. That gave me 8.5-9 hours. For the better part of a year I sat in a coffee shop a full 8 hours a day working from my laptop.
However though, as machines get faster they consume more power. I’m now looking into dual core laptops and finding that I’m going to have trouble getting even as much as 5 hours out of a laptop.
Also, hot-swappable optical drive bays seem to be going out of style, and so laptops that can take a second battery don’t seem to be as common.

W/ the IBM Ultra Bay, I’ve gotten 9.5 hrs on my old ThinkPad T21, naturally it didn’t come w/ WiFi standard, but with a CardBus adapter on low power, I still get about 7 hrs +/-.
The way I did it: I bought a Re-filled 4800MaH Primary and a 3600 Mah secondary. The trick is that I run it on the secondary first, swapping only when I needed to use the bay for my DVD/CD Burner. Just pop in the primary while still running on the secondary, and it will run seamlessly.
Just a few pointers,

(look for me on Yahoo Answers)

by the way, i saw an article on one of the business mags (time or businessweek) — featured wireless power!
It allows you to “plug-in” electrical power wirelessly.
kewl huh?
