Battery not recognised in System Preference in Ventura #93

Closed Xiashangning closed 1 year ago

Xiashangning commented 1 year ago

In Ventura, without any changes made to the battery code, the battery failed to be recognised in System Preference.

However, macOS does seem to know that there is a battery present as it can show it correctly in the control center or menu bar.

Don't know if normal laptop has this issue in Ventura or not. The battery code is almost exactly the same from SMCBatteryManager.

Ordinary notebooks also have this problem, although I don't have ordinary books, I saw the same case of oil and our problem in the Vision Forum, and the general solution seems to be compiled with the latest ECEnabler.kext to resolve

Thanks for your advice but ECEnabler won't help

I succeeded and found a workaround by modifying the error identification in the FACP table in the form of an APCI patch so that he correctly identified the Surface as a laptop. Without patching, it is identified as the type of tablet, and it will not correctly match the battery (for laptops) or energy saving (for desktops) in the settings.
