Comment 50 for bug 971061

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.
