// SSDT-BATC.dsl
|
|
//
|
|
// Based on https://github.com/RehabMan/OS-X-ACPI-Battery-Driver/blob/master/SSDT-BATC.dsl
|
|
//
|
|
// An SSDT to combine two batteries into one
|
|
// initial work/testing by ag6952563 (with assistance by RehabMan)
|
|
// finalize into generic SSDT by RehabMan
|
|
// some code cleanup/optimization/and bug fixing by RehabMan
|
|
// modifications to work VirtualSMC SMCBatteryManager by armenio
|
|
// add _BIX (easy, following the original code from RehabMan) by armenio
|
|
//
|
|
// OS X support for multiple batteries is a bit buggy.
|
|
// This SSDT can be used to combine two batteries into one,
|
|
// avoiding the bugs.
|
|
//
|
|
// It may need modification depending on the ACPI path of your
|
|
// existing battery objects.
|
|
//
|
|
|
|
// IMPORTANT:
|
|
//
|
|
// To use this SSDT, you must also patch any Notify for either BAT0 or BAT1
|
|
// objects.
|
|
//
|
|
// The Notify is used to tell the system when a battery is removed or added.
|
|
//
|
|
// Any code:
|
|
// Notify (...BAT0, ...)
|
|
// -or
|
|
// Notify (...BAT1, ...)
|
|
//
|
|
// Must be changed to:
|
|
// Notify (...BATC, ...)
|
|
//
|
|
// Refer to Dual Battery Support.md for patching details
