Battery charging status is not recognized

[Jason Robinson]

On booting my Samsung Series 5 laptop, battery charging or not charging is correctly recognized in panel power applet. However, if I unplug or plug in my adaptor, no change is reflected. The time left or time to charge seems to update correctly, the status just doesn't change.

From terminal, when power applet shows "charging":
- Plugged in:

jaywink@jaytec: pts/0: 14 files 576Kb -> acpi -b -a
Battery 0: Charging, 49%, 01:54:02 until charged
Adapter 0: on-line

- Unplugged:

jaywink@jaytec: pts/0: 14 files 584Kb -> acpi -b -a
Battery 0: Charging, 49%, 01:05:21 until charged
Adapter 0: off-line

So plugged/unplugged is recognized but not correctly reflecting to Battery 0 status.

Just a note: the bug was in fact already there on Precise 12.04 kernel - it did NOT appear in Quantal kernel testing.

This for me seems fixed, although my Samsung laptop brightness buttons cause the screen to flicker and thus are useless now :)

Not quite sure what update fixed it, possibly a driver update from Ubuntu http://ppa.launchpad.net/ubuntu-x-swat/x-updates/ Ubuntu PPA which offers updated X drivers.
