ACPI Regression, battery does not update

[David Demelier]

Hello,

Since I've updated to 9.1-* (RC3 now) my battery does not update, my laptop
is HP Probook 4510s, in fact if I unplug the AC adaptor, the remaining
capacity of the battery will not discharge and stays as the remaining
capacity from when I unplugged the adaptor.

(If that could be real... :))

And sometimes the battery is updated after a while like, when the laptop
battery change to 40% but then I won't see 39%, 38%, and so on..

I think I have the same problem as:
