New Acer laptops in 2018 will have a separate ACPI device for notifications from the airplane mode hotkey. The device name in the DSDT is SMKB and its ACPI _HID is 10251229.
For these models, when the airplane mode hotkey (Fn+F3) pressed, a query 0x02 is started in the Embedded Controller, and all this query does is a notify SMKB with the value 0x80.
Scope (_SB.PCI0.LPCB.EC0) { (...) Method (_Q02, 0, NotSerialized) // _Qxx: EC Query { HKEV (0x2, One) Notify (SMKB, 0x80) // Status Change } }
