Jake,

I have not had the issue with BIOS disabling Optimus yet.

 

Herve,

I skimmed through the guide you mentioned. However, honestly I'm not good with dsdt so I don't know what to look for. Sorry for my ignorance but can you provide a patch file or patch my dsdt file?

 

attached is a screenshot right before KP. It hangs for 20~30 seconds at ACPI then KP, only on reboot. 

DSDT.aml

Hi Herve,

I made my own dsdt and applied the Rehabman's USB3_PRW 0x0D patch which seems to have fixed instant wake on sleep.  However, I get a kernel panic on reboot.  Cold boot or shutdown & boot seems to work fine though. Any idea what the problem might be?

Thanks for your help again.

So after much trial and error, I finally got my laptop working again. I have Clover kext injection set to Detect and see the following lines in clover boot log so I must have generated correct SSDT for my laptop.

Sleep still does not work though. It appears my laptop goes to sleep but wakes up immediately.  Sometimes after booting I get blank/black screen and looks as if the laptop is about to go to sleep mode. Pressing a key usually get the login screen back. 

 

I tried my own dsdt.aml per Pokenguyen's guide but I get a kernel panic every other boot and even if it boots up, sleep still does not work.  I will do some more research next weekend but I'm ok for now.

Herve,

So I tried what you recommended and now my laptop wont boot up at all.  attached is a couple of screen captures before reboot.

 

 

Herve,

Thanks for your help. Sound works now. However, I got this error upon first reboot after adding/updating kext files you mentioned. My laptop came up fine on the second reboot.  Any idea what this is about?

Hello Jake,

So I was able to install High Sierra on my 6530 using the exact same EFI you mentioned above. My laptop works fine for the most part but I could not get sound working and sleep function does not work. I have attached my EFI folder with untouched dsdt in origin folder. When you get a chance, can you take a look? Thanks.
