I can confirm this bug an a NX9030 running . I am currently using it on battery after unplugging it, the tooltip says the Computer is currently on battery power, however the icon is displaying an empty battery which is charging.
I am using kernel version 2.6.15-23-386. If you need any extra info, I will be happy to help. Adam -- Incorrect battery status on HP compaq nx9030 laptop https://launchpad.net/bugs/21435 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
