Ok man!

I've installed Yosemite again and then applied PBI fixes for 2x70p Business Laptops (only KernelAndKextPatches, no DSDT)

working: HD4000 (vga port not tested), USB/SD-CR/Camera, WiFi (Atheros 9285), Bluetooth (Qualcom Atheros), Ethernet

not working: Battery status (only X), Audio (IDT 92HD81B1X), WWAN (HP lt2523), Fn Keys


How can I resolve?

Thanks!

There's your mistake. Follow the guide.

@RehabMan I only install your kext and my laptop work. It is 10.10.2 with DSDT and SSDT patch follow your guide. It show the battery percent. I don't know how this possible?

Some DSDTs don't need patching (eg. they have no multibyte EC fields). It is rare, but it happens.

You should make sure you don't have a rollback AppleACPIPlatform.kext.

Check the version with: "kextstat|grep -y acpiplat" in Terminal. For Yosemite, it should be v3.1.

Yes it 's v3.1:
13 2 0xffffff7f82112000 0x65000 0x65000 com.apple.driver.AppleACPIPlatform (3.1) <12 11 7 6 5 4 3 1>

You can add the note for someone try to make battery work(At least with MSI gaming laptop). This is my process:

1, Get all tables from ubuntu
2, Compile all with -da option.
3, Fix with your Laptop patch with basic option.
4, Install your ACPIBatteryManager.kext and it work, DropOem =true.

As you've found, you don't need DSDT patches. No note necessary here.
