Public bug reported:
acpi fails to detect reconnected ac adapter Acer c710 running kubuntu
14.10. To reproduce: Start running on AC adapter - power is sourced from
AC adapter. Disconnect AC adapter and then it runs on battery. Reconnect
AC adapter and laptop continues running on battery until they battery
runs out and system shuts down. Problem is that software fails to detect
AC adapter after reconnection.
Command 'fwts ac_adapter' reports 4 fails (i..e. each of its four tests
failed.)
After AC adapter is reconnected in above:
'acpi -i' reports:
Battery 0: Discharging, 20%, 00:49:33 remaining
Battery 0: design capacity 2500 mAh, last full capacity 2241 mAh = 89%
'upower -d' output includes:
/org/frfeedesktop/Upower/devices/line_power_AC
...
line-power online: no
Daemon:
...
on-battery: yes
--
The only way to get AC Adapter to charge battery is to power the system down.
At that point, the LED indicator shows the AC Adapter is then charging battery.
The system can also then be immediately restarted and the connected AC adapter
will supply power. After rebooting, while still on AC Adapter:
'acpi -i' reports:
Battery 0: Charging, 19%, 01:31:52 until charged
Battery 0: design capacity 2500 mAh, last full capacity 2241 mAh = 89%

running 'fwts ac_adapter'
(with AC adapter still connected from powerup) gives the following (my actions
are in brackets):
==== Make sure laptop is still connected to the mains power . ====
Press <Enter> to continue
(I press enter)
==== Please unplug the laptop power. ====
(I unplug it. Charging light stays on until 20 second countdown ends. Then the
charging light goes out,
there is a beep, the please reconnect line shown below is typed by the program,
and it then goes right
to the command line prompt without reporting the test results.)
==== Please re-connect the laptop power. ====
