Bug Description

Binary package hint: gnome-power-manager

The option to 'do nothing' when the battery reaches critical level has been removed. This means I am unable in Ubuntu to run my battery down to 0% to recalibrate it. This was introduced in version 10.04 which means I haven't been able to re-calibrate my battery in months and it's starting to suffer as a result with the capacity constantly reducing.

Please can you re-instate the option so I can properly re-calibrate my battery once again.

Of course it dissapeared, i think it should be a good idea to restore that option, if i am sincerely i have never recalibrated my battery, but i think this is not a bug.

With all due respect flipefr, the fact that you haven't needed to do something by no means that others do not.

Personally, I have never been in a car accident of the type that I can say a seatbelt saved my life. If someone pointed out that a car had no seatbelts, I wouldn't blow them off as you did the bug reporter.

The absence of a previously available feature, which had a definite use, is certainly a reportable bug on Launchpad. You brainstorm NEW ideas. You report broken or inappropriately unavailable features.

Whether this is a bug, a mistake or a really misguided decision, it has been reported and should be respected.

This affects me as well. Perhaps you will next suggest that I get an ARCH live-cd to accomplish what was easily done in Ubuntu last year?

I would also like to get the option to ignore the charging state since my battery on Packard Bell DOT S2/RU is sometimes shows weird time and I want to re-calibrate. Have to enter BIOS to discharge the battery at the moment, but it takes way too much time.

Yep, this is more like a regression bug than anything else. I can see that the choice has been made to protect stupid user from losing data, but this isn't how it should have been done. Add a warning dialog or something if you need to, but please let user decide on this.

It's really annoying to have a brick on your lap while knowing that there's actually 4 hours juice left on battery, it's just the $0.01 dumb chip on a two year old battery that says it's critical. Regular user shouldn't need to go to gconf-editor to work around this.

Calibrating doesn't seem to be long term solution either for some batteries, and there's no easy fix for that.

A workaround (at least on 10.04):

Using gconf-editor, change /apps/gnome-power-manager/actions/critical_battery to "nothing". Power manager GUI does recognize this, too, unless you change it back.
