Bug Description
Binary package hint: gnome-power-manager
When an older battery is fully charged and connected to AC, the "Current Charge" entry shows the same value as "Design Charge". After unplugging AC and waiting 1-2 minutes, Current Charge jumps to the actual charge of the battery.
Here my battery:
Product: Laptop battery
Status: Charged
Percentage charge: 100.0%
Vendor: Samsung SDI
Technology: Lithium Ion
Serial number: 51645
Model: DELL PC7647
Capacity: 88.2% (Fair)
Current charge: 57.7 Wh
Design charge: 57.7 Wh
Charge rate: 0.0 W
After unplugging, Current Charge will jump to 50.2 Wh (or so). I don't know if this is my battery misreporting it's status, but cannot remember seeing this bug before karmic.

Interestingly,
the real energy is reported correctly:
battery. charge_ level.current = 50882 (0xc6c2) (int) charge_ level.design = 57720 (0xe178) (int) charge_ level.last_ full = 50882 (0xc6c2) (int) charge_ level.percentag e = 100 (0x64) (int)

But DeviceKit mixes something up: p/DeviceKit/ Power/devices/ battery_ BAT0 full-design: 57.72 Wh
