dsktoni

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. 5:493 0:000 === [ ACPIPatchedAML ] ==================================== 5:493 0:000 Unsorted 5:493 0:000 Inserting SSDT-1.AML from EFI\CLOVER\ACPI\patched: size=6538 ...

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. BIOS: A20 | i7-3720QM | 16GB | nVidia 5200M (Optimus enabled in BIOS) | 1920x1080 EFI.zip
