Subject: [PATCH] acpi/battery: Add device HID and quirk for Microsoft Surface
|
|
|
|
|
Go 3
|
|
|
|
|
|
|
|
|
|
For some reason, the Microsoft Surface Go 3 uses the standard ACPI
|
|
|
|
|
interface for battery information, but does not use the standard PNP0C0A
|
|
|
|
|
HID. Instead it uses MSHW0146 as identifier. Add that ID to the driver
|
|
|
|
|
as this seems to work well.
|
|
|
|
|
|
|
|
|
|
Additionally, the power state is not updated immediately after the AC
|
|
|
|
|
has been (un-)plugged, so add the respective quirk for that.
