Can you paste the output of `upower -d` when the machine is in this state?

I update the files

From UPower's perspective, the battery is charging:

  battery
    present:             yes
    state:               charging

If that does not accurately reflect the true charging status, there is an issue much deeper in the stack. Seems like this restriction must happen at the firmware or PMU level. I suspect this is a scummy intentional limitation that Dell imposes just to be assholes to their customers. :( Some laptop manufacturers periodically do this; HP has also done it in the past. There isn't any way we can work around this. If you feel that you can't live with this limitation, the best advice I can give is to avoid Dell's hardware in the future, or return it and get something from another manufacturer.
