gnome-power-manager

I have a Lenovo Y460p running Ubuntu 12.04 (64-bit). The battery does charge normally, but unplugging the power supply only very briefly shows the correct battery indicator. After about 1 second, it reverts to the charging indicator.

If the power supply is connected the power statistics show:

"Supply Yes"
"Online Yes"

If it is not connected it shows:

"Supply Yes"
"Online No"

My problem is almost exactly like the one in this post: Ubuntu 11.10 power management does not recognize removal of power supply

The only exception is that my system does not dual-boot with Windows. This is Ubuntu only. The computer in the other post is a Lenovo as well; not sure if that has anything to do with it.

Any help would be greatly appreciated. Thanks.
