Get rid of your “battery may be broken” notification

Some HP Pavilion standard 6 cells batteries apparently use the same ID of 12 cells batteries. This would lead GNOME to display the following notification at every login:

Battery may be broken
Your battery has a very low capacity 48% which means that it may be old or broken.

Of course M$ windows wouldn’t care a bit about your battery health status and thus not annoy you with any message.

Fortunately your battery is not broken but simply not carefully crafted. This is not a big deal though. You can get rid of the “battery may be broken” message by typing

ALT+F2
gconf-editor

navigate to

/apps/gnome-power-manager/notify/low_capacity

and untick the value.

At the following login you would see that message no more.

    Thanks for post. That was starting to get annoying :-p

    Great post – I’m using Lubuntu, but the same applies – just install gconf-editor with

    sudo apt-get install gconf-editor

    then run with

    gconf-editor

    and navigate to the path given in the post above, unticking the option.

    Thanks for this. I’m using an Acer eeePC and was getting the same error with Debian Squeeze and Lubuntu 10.04 Beta.

    Thank you, this was exactly what I was looking for! I was getting tired of seeing that error every time I logged in, now no more…

      spacelee, as far as I know there is no way a piece of software (Ubuntu) can damage a battery. Given that basically is simply drained and recharged by the electronics controlled by the BIOS (not the Operative System!) and it cannot be overclocked in any way there are no chances that it’s Ubuntu Linux’s fault.
      Poor quality batteries perform very well at the beginning, hence when you were using windows it was working great! However quality issues or frequent and intense charge/discharge cycles would let the battery have a very short life, regardless to the software that benefits from its power.

      In other circumstances there could be the case a not tweaked program or operative system may drain more power from the battery, hence reducing its performance, however in your case the last full capacity: 15210 mWh is indeed 25% of the design capacity. This means that is the battery itself that is broken.

      In my case, instead, the battery simply has a misconfigured identity chip, so that the design charge is the one of 12 cells version, whereas my device has 6 cells only. The last full capacity value, actually, reports 95% of the 6 cells battery design capacity even after 2 years (during which it has undergone very few discharge/recharge cycles though since I mostly use the laptop in AC mode).

        I would add that – I don’t know with 10.04 but it was so with previous Ubuntus – Ubuntu is quite weak on the power management side, so maybe that’s part of the problem. Your battery is weakened indeed but nevertheless it managed to get you better performance under windows.

    Well, my battery really *is* broken but I was getting sick of hearing about it anyway :)

    Thanks for the tip.

    Damn, I went and bought a new battery last week. Slams head.

    Should’ve kept up to date with aldeby…

    At least now I know to keep the old battery. I want to keep this HP Pavillion for as long as possible.
