how to set charging limit in gnome

#2

What do you mean by a charging Limit? What openSUSE and Gnome version is this for? What problems are you having now? Does your Laptop battery not charge or what is going on? More information can be helpful in providing a useful answer.

Thank You,

You’ll have to tell us a little more. Such as:

  1. What version of openSUSE you’re using.
  2. What hardware you’re using
  3. What you are specifically talking about (“charging limit” has no
    meaning to me. I might /assume/ you mean something about a laptop
    battery, but maybe you mean something else.)

It’s important to be clear in your questions and to provide information
that is necessary to answering your question.

laptop battery charging limit to 50% or 80%

#5

As far as I know I have seen no such limit before, but the real question for me is why to do this? What problem are you trying to fix?

Thank You,

Hi
What hardware? If you have a Lenovo you can
http://www.thinkwiki.org/wiki/Tp_smapi

You would need to build the utility then something like;


echo 50 > /sys/devices/platform/smapi/BAT0/stop_charge_thresh
echo 80 > /sys/devices/platform/smapi/BAT0/stop_charge_thresh

To set a start for example when it gets to 30%
echo 30 > /sys/devices/platform/smapi/BAT0/start_charge_thresh

Such a feature is not part of any operating system since charging the
battery is not controlled by the operating system but the laptops hardware.
I know that for certain models there exists some windows applications
which can communicate with the hardware to tell it at which percentage
to stop loading the battery, but this are special programs from the
hardware manufacturer.
You need to ask the vendor of your special laptop model if such a
software exists for linux and if so how to get and implement it.
Btw this kind of feature never in my live made any sense to me since a
laptop is mainly a mobile device and its purpose is that one charge of a
battery lasts as long as possible and not that I have an unusable
battery which does not last that long when uncharging it but get a
longer overall lifetime until I have to replace it, IMHO that whole
philosophy behind that kind of tools is utter nonsense.

For a ThinkPad this is installed by openSUSE out of the box at least in
12.1, no need to build anything.
I never touch that feature, I love my hardware too much to play with
such experimental features.

Again, you need to tell us:

  1. What version of openSUSE you’re using.
  2. What hardware you’re using

Don’t make people guess what you have, tell us what you have so we can
help you. We’re not psychic, and we only know what you actually tell us.

I’ve read some reviews on new powerbooks or such stating that there is a considerable increase in batery life when limiting charge to 80% or less of battery capacity - which would only make sense if the number of charge cicles would at least be twice than when fully charging.

If that is so - and I’ll really believe it when such batteries would start showing their age, perhaps one year from now - I can see the appeal, specially in a powerbook (supernotes, whatever they’re called), where the “power” part may not be necessary when in transit. Different needs, different solutions.

Just my 2 cents…
