Instead one can take the time and add some rules to the udev or write some for acpi, and of course enabling laptop-mode and there is so much more one could do. I got like this 1h more power than on windows vista and my laptop goes automatically to hibernation on 6%. One should drain the battery every few months to reset the chip inside (callibrate). http://www.batteryuniversity.com/ good luck draining the battery (LION) is a bad idea… squeezing practices like described here left me with a damaged 6months old sony-battery…which now gives me 5minutes of power and half day of sleep… Instead one can take the time and add some rules to the udev or write some for acpi, and of course enabling laptop-mode and there is so much more one could do.

I still do this same trick on every notebook that I install Ubuntu on, and occasionally need to do it again after six or seven months. :eek: Heh, thanks for the update on that, Dirty Cutmaster.

Have you tried anything like this and found favourable results?" Yep. Worked for me on 4 different notebooks so far. I noticed that half year ago on my HP6715s (hard work to get Ubuntu running on that, but it finally ran). After reading your post I remembered and tried it on 3 other notebooks (Dell & IBM, all with 8.10) - and it worked again! Is it finally ...errhem... "a feature, not a bug"? :mrgreen: “Do you run Ubuntu? Have you tried anything like this and found favourable results?”

What I've noticed is that the battery meter is incredibly pessimistic and, if you disable the "auto-shutdown", you can squeeze quite a bit more life out of it. The system will still let you know when you're running low on power, of course, but even with my 5 year old notebook, I was able to squeeze about 30 minutes out of the battery when Ubuntu said it was at 0%. Check out my other post, <a href="http://www.j2fi.net/2007/12/18/taking-ubuntus-battery-warnings-with-a-grain-of-salt/" title="j2fi.net | Taking Ubuntu's Battery Warnings With A Grain of Salt" rel="nofollow">Taking Ubuntu's Battery Warnings With A Grain of Salt</a>. You might just be surprised how long the battery can last in Ubuntu with your usual selection of peripherals. Have you let the battery run right down to nothing, Lala?

Compared to Windows, which I could run it for about 6 hours, on the same laptop with the same battery, Ubuntu only last about half of it. When it comes to battery life on a laptop, Ubuntu's the biggest, biggest, biggest loser. What a shame, man. It's great for a desktop, but when it comes to laptop, it sucks a whole lot.

Dr Pepper was new to Australia, so they introduced a competition where if you flipped the lid of your 500ml bottle, you had a 50-50 chance of getting a free bottle. And when you handed over the cap, the bottle you got also had a 50-50 chance. My record was 13 bottles free in a row, though one of my classmates got 26. Hmm.. Tell me if its more interesting than watching your laptop run down.... It all started when I was in technical college.

That soft drink has helped me through many-a-sleepless coding nights. They should really change their slogan to: DP! Helping You Get That Project Done On Time! :P @Jake: Did you have to do anything special to get that much life out of your notebook batteries? I've been trying so many things to get my notebook operating for a longer time on battery as it's important to keep mobility up, but haven't really found much that can be easily handled by family should they choose to use the machine while I'm away. That said, it seems that since running the battery into the ground, it's been working great for everyone. I'm thinking the next area I'll tackle will involve setting aside some RAM as a RAM drive and having the system run almost exclusively off that with targeted copy-backs on shutdown (should it be necessary). It'll likely be a bit more tricky than just a scripted action, but it shouldn't be *too* difficult. Once I can get the hard drive powered down for 90% of the time, then runtimes will really soar :D @Contamination: What’s wrong with talking about our love for DP?
