osul said:

First of all, thx for this fantastic website. My Samsung NP350V5c is now 95% working in 10.9.2 with clover bootloader.

There are one thing that I can't fix even after searched this forum and google. It is how to disable the ATI HD7730M in dsdt. I have already realized I can't get it work with the intel 4000 together, however, for energy saving, I would like to disable it through dsdt.

Please kindly give me a hand.

Thanks for your reply.
After reading the post i have patched the DSDT successfully without error with the HP ProBook repo.
However, When I tried to patch the SSDT6 file, no matter it is extract by ubuntu or aida64, it shows an error when compile.

Method (_PRW, 0, NotSerialized) // _PRW: Power Resources for Wake
{
Return (GPRW)
0x09
0x04
}
syntax error unexpected parseop_integer

Changing the code to "Return (GPRW (0x09,0x04))" also report error.
I have tried to disassemble[FONT=Verdana, Geneva, sans-serif] it with the latest version of iasl, but the problem remains.

Please kindly suggest what should I do.

Thanks a lot.

I have tried to use the latest iasl for the SSDTs generated from ubuntu and windows with the code you provided. And when I compile the generated dsl files, I have got the same error.

Please kindly help.

If you disassemble your DSDT/SSDTs as described in post #4, your DSDT compiles without errors.

Sorry, I am so idiotic that did disassemble them without the DSDT....Now the SSDT5 can be compile after patched without error. However...the ATI card still display at system report as GPU Display PCIE.

I did apply the patch on both DSDT and SSDT-1 as attached.
I also provided the IOReg for your reference.

Please suggest what should I do next.

Thanks a lot for your kindest help.
