Dell Inspiron on kernel 4.10 : battery detected only after AC power adapter event

[Xavier Gnata <xavier.gnata@xxxxxxxxx>]

Hi,

When I boot a Dell 15" serie 7000 with or without it AC power adapter no 
battery is detected:

acpi -i -b -a
Adapter 0: off-line

As soon as I plug or unplug the AC adapter, the battery is detected:
acpi -i -b -a
Battery 0: Charging, 62%, 01:13:00 until charged
Battery 0: design capacity 3950 mAh, last full capacity 3850 mAh = 97%
Adapter 0: on-line

cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-4.10.0-13-generic 
root=UUID=42930a1e-fbdc-4cd8-a1d2-caf2bd33de1b ro acpi_osi=Linux quiet 
splash vt.handoff=7

I've tried with and without acpi_osi=Linux but it makes no difference.

Attached : dmesg and dsdt. What else do you need?
Looks like a buggy dsdt table but I'm not an expert.
