I have got a bit different problem with battery info on HP notebook but it may have the same root cause.
I use acpi -V and new battery applet in Gnome system tray to monitor the battery state and it works fine. If I suspend to disk and then resume with different AC-present state the acpi command and battery applet don't register the change and still show the old state. Maybe there is lack of suspend support in battery monitoring code which causes both our bugs? -- Battery info lost after suspend to ram https://launchpad.net/bugs/28303 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
