I recently bought a MSI-X370 laptop with ATI graphics and wiped Windows and replaced with Ubuntu 12.04.
Now, up until my upgrade from beta 2 to the first stable Ubuntu 12.04 release, I didn't have problems with this.
This is the problem: ACPI knows that my battery capacity is 4400mAh, but only randomly charges fully ever. Otherwise, it charges to around 86%, and I get a orange light blinking on the laptop, and my acpi -V says that I'm charged to 100%. The strange thing is, that I do a cat info again, and it is still not charged to capacity. Why the discrepancy? Did something change in acpi, upower, gnome-power-manager? I am lost, and no one seems to want to assist.
