bug : Dell Inspiron 15 7000 : battery detection only after AC power adapter event.
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
Attached : dmesg and dsdt.dsl. What else do you need? Looks like a buggy dsdt table but I'm not an expert.
The bug is the same on 3.17-rc1, 3.16.1 and 3.13.

As a workaround one can boot with acpi_osi=Linux . I don't see any side effects.
