Please provide a clear/detailed description of the problem.

Please provide a clear/detailed description of the problem.

Hi, I follow the method above you to my Surface Pro 3 battery patch, and used ACPIBatteryManager.kext (the current version is RehabMan-Battery-2014-1016), and I found some bug, specifically a normal display power, while the emergence of a small battery fork. I have tried a higher version (including version 2017). For me, only a small battery fork is displayed after the boot (there is no indication of power at all). The system is macOS 10.12.6.

Note: it has been put on“Fix Mutex with non-zero SyncLevel” but still ineffective

Is that my patch problem or ACPIBatteryManager.kext's problem? Could you please take a look at it for me? Thank you very much.

Your description is not clear.
Perhaps you should use images to explain (please no video).

It is my DSDT a patch according to above methods, and the use of "Fix Mutex with non-zero SyncLevel", but after the start of a normal battery can read power, then it becomes a small fork , changed a few versions of the "ACPIBatteryManager.kext" effect is not so good! What should I do?

Your ioreg shows multiple battery objects active (BAT0, BAT1).
But there is only a battery attached to BAT0, not BAT1.
As per post #1, you must disable the BAT1 by returning zero from _STA.

How should I change it? I'm a new hand, not very well. Could you direct me?

There are plenty of examples of patching _STA in the repo...
