Sorry, it is not clear. Do I have to follow whole that instructions or just copy the code after Begin...... if so, which method do I have to change in my DSDT? XHC?

 

Updated:

I patched my DSDT in XHC. I remove method _PWR and replaced method _DSM. There is no more instant wake, but internal screen still black.

try this boot arg

-igfxmlr

[Limaho]

@Jake Lo Still black screen.

@Jake Lo do you think this is unsolvable? I have tried different methods but still nothing.

[Jake Lo]

why do you have device_type set to VGA Compatible?

try this Config 

config.plist.zip

[Limaho]

@Jake Lo I used the new config.plist but still black screen after wake

[Jake Lo]

Can you post new debug file?

[Limaho]

@Jake Lo New debug file. 

Thanks for everything.
