Battery

danes · 2005-10-27 04:00:19

Hi guys...

I have a Dell Inspiron 8200

I tried to configure my acpi, but I read about DELL laptops, and I found only APM configure, so I changed to APM, but everytime I use my battery I just get 1 hr left.

It's been the same with ACPI and APM, how can I fix it? I mean, to get more time left in my battery.

best regards.

are you using any kind of cpu frequency scaling??

like the one in the kernel, or a program like powernowd/cpudyn?

that will help you with your battery time, but if you use that, then probably the battery is dying, i mean, I have a dell inspiron 8500 and my battery is as good as dead...it has around 5-10 minutes on full speed and 30-40 miniutes when speed is low..

You could also try using cpufreq and laptop-mode-tools located in the community repos. Expanded my battery-life with about 30%.

How to use them?

cpufreq does the same thing as powernowd, powernowd (it is in the aur) works like this: install it, run it (add it to daemons) and voila, it lowers the cpu speed automatically (no configs needed)

and laptop-mode-tools, they are a package that takes some minutes to configure, but when it is configured it lowers the harddrive (put's it to sleep)
and stuff like that..

The kernel mode cpufreq governors work very well too, things like powernowd and cpufreqd use the "userspace" governor... you can use the cpufrequtils package (and daemon) in the AUR to use any of the kernel mode governors. Personally, I use "ondemand" which keeps the cpu frequency at a set minimum until the load get's sufficiently high to warrant bumping it up

I don't think ondemenad works with inspiron 8200 (it doesn't work with my 8500)

You need the proper cpufreq_* module for your processor in order to use the governors.

I know, and I have...it just doesn't work..it wont even load the governer..the other two, powersave and performance works

but neither conservative nor ondemand works

so powernowd does the trick for me works perfect

today my laptop was showing about 35% charge with hour and a half left. then suddenly in couple of minutes i got a message saying only three minutes are remaining. this problem happened to me for couple of times.

i am running latest 2.6.36 kernel with KDE 4.5.

how do i determine if the software is configured incorrectly or it is actually a bad battery. the laptop and battery are about couple of years old so they are relatively old.

any help and suggestion appreciated.
