Comment 32 for bug 1283589

Just in case the NP400x4C (Ivy Bridge version) give different values, here are the results of acpi -i -b -a on this system.

** AC Off **

Battery 0: Discharging, 70%, 03:46:06 remaining
Battery 0: design capacity 8400 mAh, last full capacity 8700 mAh = 100%
Adapter 0: off-line

** AC On **

Battery 0: Discharging, 70%, 01:55:16 remaining
Battery 0: design capacity 8400 mAh, last full capacity 8700 mAh = 100%
Adapter 0: on-line

** Suspend and wake **

** AC Still On **

Battery 0: Charging, 70%, 00:50:05 until charged
Battery 0: design capacity 8400 mAh, last full capacity 8700 mAh = 100%
Adapter 0: on-line

** AC Off **

Battery 0: Charging, 70%, 02:11:35 until charged
Battery 0: design capacity 8400 mAh, last full capacity 8700 mAh = 100%
Adapter 0: off-line

** Suspend and wake in this state **

** AC Off **

Battery 0: Discharging, 70%, 05:06:01 remaining
Battery 0: design capacity 8400 mAh, last full capacity 8700 mAh = 100%
Adapter 0: off-line

** AC On **

Battery 0: Discharging, 70%, 406:00:00 remaining
Battery 0: design capacity 8400 mAh, last full capacity 8700 mAh = 100%
Adapter 0: on-line

What I find quite interesting about these is that the times change as the AC state changes and seem to reflect the "correct" time, i.e. time to discharge when disconnected and time to charged when connected. So something is detecting the change, it's just not propagating to all properties.
