detecting "discharging" is wrong

[cherep]

Binary package hint: gnome-power-manager

Ubuntu 10.10 64bit,
gnome-power-manager

when the battery is discharging, the indicator applet shows "charging". This case serious problems for my computer because when the battery level is low, it doesn't go to suspend or it doesn't shut down correctly!!!

I've got the same machine (Lenovo Z360) with the same problem. While not plugged, acpi says that the battery status "charging".

Before I switched to Linux Ubuntu, I had used Windows where I chose an option to the case when my battery is charged up to 80% to maximize LIFETIME of the battery like it is described here:

I did it in Lenovo Energy Management. Have you done the same? It might be a source of the problem :)

I could solve this problem by taking the battery out and plugging it back after a while. The status is detected correctly. Moreover, the battery is charging to 100% now.
I hope it will help!

Thanks for the report, it has been some time without any response or feedback in this bug report and we are wondering if this is still an issue for you with the latest release of Ubuntu the Natty Narwhal, May you please test with that version and comment back if you're still having or not the issue? Please have a look at http://www.ubuntu.com/download to know how to install that version.Thanks in advance and sorry for the late response.

[cherep (acherep)]

Yes, the bug does remain in Natty!
