sku: SP3-DVT2-C1,
As AC is plugged, there are endless BAT0 udev event per check
After check the finding is the BTP threshold didn't update.

ACPI SPEC
10.2.2.8 _BTP (Battery Trip Point)
This object is used to set a trip point to generate an SCI whenever the
Battery Remaining Capacity
reaches or crosses the value specified in the _BTP object. Specifically, if
Battery Remaining Capacity is
less than the last argument passed to _BTP, a notification must be issued
when the value of Battery
Remaining Capacity rises to be greater than or equal to this trip-point
value. Similarly, if Battery
Remaining Capacity is greater than the last argument passed to _BTP, a
notification must be issued when
the value of Battery Remaining Capacity falls to be less than or equal to
this trip-point value. The last
argument passed to _BTP will be kept by the system.
If the battery does not support this function, the _BTP control method is not
located in the namespace. In
this case, the OS must poll the Battery Remaining Capacity value.
