As soon as I plug or unplug the AC adapter, the battery is detected:

Battery 0: Charging, 62%, 01:13:00 until charged
Battery 0: design capacity 3950 mAh, last full capacity 3850 mAh = 97%

I've tried with and without acpi_osi=Linux but it makes no difference.
Attached : dmesg and dsdt in http:// www.spinics. net/lists/ linux-acpi/ msg73101. html 4.10.0- 13-generic
I think that acpi_osi=Linux used to do the trick but it does not work on vmlinuz-
