[Guide] Patching LAPTOP DSDT/SSDTs

[ikador]

you can mess around with that, maybe use "cpufriend" to lower the frequency to get a little more battery life, you can research that if you like

Hello.
I am new here. I tried to use almost every IASL and MaciASL version in order to modify my DSDT file.

And yes, I also used RehabMan iasl/MaciASL files.

I used all of the available Compiler Options with 5.0A,5.1,6.0, 6.2a, 6.3 ... Nothing works for me ...

I have a Lenovo C930 with i7-8550u, 620UHD etc.
For this Notebook there is already a guide in this forum. There it is mentioned that I need to modify the DSDT file in order to get touch screen, touch pad, native USB 3.1 and also maybe thunderbolt to work.

But I can't compile ... always have errors ... and I don't know how to fix it.
Maybe someone can have a look inside my file. Here the attachment.

Thank you already so far.

using:

iasl -dl DSDT.aml SSDT*.aml

and using iasl from Rehabman:

https://bitbucket.org/RehabMan/acpica/downloads/iasl.zip

results in no errors

also you could try a battery patch that is already present in macIASL, one of those may do the job for you, you will have to trial and error, but only patch 1 battery patch at a time, go back to a clean dsdt.dsl if you need to test another patch
