Ok, you have a different model to mine which explains why I couldn't find the firmware version you mentioned :)
I have the NP530U3C and as it currently stands the best workaround for this problem for me is: - shutdown the laptop - insert a pin or staple into the little hole on the bottom of the laptop to shut off power from the battery - Then plug the laptop into the power and re-start it After that the ACPI detection of battery state and whether the AC adapter is plugged in or not works perfectly in Ubuntu, but eventually stops working again after a few suspend/resume cycles. Really annoying but not enough to stop me using the laptop. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/971061 Title: acpi reports battery state incorrectly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/acpi/+bug/971061/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
