The kernel was updated after bug #775809, which is now marked resolved. I can confirm the exact same behavior as Henryk after the update -- no more wrong reporting, but sometimes two batteries on the notification overlay -- on a Thinkpad T410s. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/626025 Title: ThinkPad battery applet shows incorrect information To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/devicekit-power/+bug/626025/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 626025] Re: ThinkPad battery applet shows incorrect information
Apparently a fix for this had been committed to the linux kernel in January (based on the Fedora fix mentioned in comment 10: https://bugzilla.redhat.com/show_bug.cgi?id=656738 ) but was then removed a couple days later by Linus because it freezed his EeePC. A new fix has been added a few days ago: http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.38.y.git;a=commitdiff;h=36d08a041f93f2c5370f95f9611c9065bb79e4fb and is already included in vanilla 2.6.38.5. There even is an Ubuntu bug #775809 to upgrade the kernel to 2.6.38.5, so when that is through it should fix this bug. I've compiled that kernel myself (based on the current Ubuntu natty kernel sources) and tried it on my Thinkpad T510 and so far the battery capacity display stayed sane over a couple of suspend/resume cycles, while previously it would go wahoonie-shaped after just one resume-on- battery. This fix introduces a new issue though, which is hopefully mostly cosmetic: Both the menu that pops up when clicking on the battery indicator and the notification overlay, but not gnome-power-statistics, show two batteries (with same time left) after the first suspend/resume cycle when the bug would normally occur. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/626025 Title: ThinkPad battery applet shows incorrect information -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I think I might have found a clue as to where the bug originates: hen...@aurora:~$ upower -d | grep energy: energy: 9.025 Wh hen...@aurora:~$ grep remaining\ capacity: /proc/acpi/battery/BAT0/state remaining capacity: 9025 mAh It may very well be that the acpi interface changes units under certain circumstances: A - W. This would explain why the values are off by approximately, but not exactly, a factor of 10: The voltage is 11-13 V, which is almost 10. -- ThinkPad battery applet shows incorrect information https://bugs.launchpad.net/bugs/626025 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It's a nasty hack, I know, but so far, putting a script containing the following in /etc/apm/resume.d seems to work round the problem for me (based on David's workaround): #!/bin/sh sleep 15 killall upowerd /usr/lib/upower/upowerd --verbose Any improvements to that welcomed. -- ThinkPad battery applet shows incorrect information https://bugs.launchpad.net/bugs/626025 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Linking similar Fedora issue. The Fedora issue is about upower showing 10x the expected full capacity but the correct charge capacity. This is the opposite of my issue, but the root cause is probably the same. Both issues affect ThinkPads and show an order-of-magnitude problem. -- ThinkPad battery applet shows incorrect information https://bugs.launchpad.net/bugs/626025 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
