Title:
Dell Inspiron on kernel 4.10 : battery detected only after AC power
adapter event
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hi,
I already reported the bug here:
http://www.spinics.net/lists/linux-acpi/msg73101.html
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 in
http://www.spinics.net/lists/linux-acpi/msg73101.html
I think that acpi_osi=Linux used to do the trick but it does not work on
vmlinuz-4.10.0-13-generic
