      This is the way I patched my DSDT and SSDTs to get perfect sleep/wake and USB ports on my Skylark i7-6600u HD520 HP EliteBook 820 G3.

      I tried to patch my DSDT.dsl. for Catalina 10.15.4
      i am searching alink where all the error have solution(if know then please share)
      Solved few errors but stuck in those---

      3107, Reserved method must return a value (Integer/String/Buffer/Package/Reference required for _DSM)
      3124, Switch expression is not a static Integer/Buffer/String data type, defaulting to Integer
      3130, Result is not used, possible operator timeout will be missed

      Can anyone tell me how to resolve this problem and any help should be apritiatable.

      Hello everyone i have a sony vaio svd1321Z9E intel i7-4500U/4400HD and 8G of ram and using opencore 5.6
      I made a battery patch following rehabman tutorials and i think the patch looks good, but when i try to load it with the kext my pc won't boot to the home menu.

      Like i it does the verbose boot then show me a grey glitchy screen with scattered apple logo.

      Normally it should give this screen then immediately turn into a black apple loading screen (still glitchy) and then return back to normal once it boot into the desktop menu of mac os. (my gpu problem that i never managed to fix but doesn't bother me)

      I would like to know how i could debug and solve this problem. Any help is appreciated.
      Here are my DSDT, config and my battery patch

      It's been known that there is indeed support for VGA in Coffe Lake and that support for prior iGPUs was deprecated as the VGA port was removed since Sierra. However, using port patches in Devices Properties (Open Core), I made the VGA port to work again with graphics acceleration.
      But there's a catch, the port is glitchy. Once macOS displays the accounts, you can see the Enter Password box with the blur effect. But after some seconds, the whole display will turn to another color (depends on the background). I'm not sure why that happens.
      I would suggest learning what are Ports, Connectors, Indexes, Types, and BusIDs before continuing, otherwise, you would get lost.
      These are the patches that are supposed to enable the VGA port according to the Whatevergreen Intel guide:
      06020000 02000000 30000000 // Option 1 06020000 01000000 30000000 // Option 2 None of those ports seem to work. The first problem is that the Index is 6, which does not make any sense as the Azul framebuffer only supports up to 3 Indexes (software ports). So we first have to change the Index for the VGA port on your motherboard, which is 2 (physical port is 0x06)) for me.
      So that means that the target port is the Index 2, which is 02040A00 00040000 87000000.
      bus-id 4 is for DP so we would change that to 2, which is VGA. That is according to what Hackintool says. I also proved other bus-ids but none of the other ones seem to work.
      I have no idea what pipe does so I just type zeros.
      I think pipe is basically another way group ports. So later I changed that to 10, which is 0A in hex. That means pipe remains the same as it was originally.  02020A00 01000000 87000000
      The next part is the connector-type, for which I used 02000000.
      I tried the VGA connector-types that Hackintool suggested but I noted some weird differences whereas 02000000 and 01000000 seem to work okay.
      Finally, I don't know what flags do so I tried with 30000000 and 87000000. The only difference is that with 87000000 I'd gain more seconds before the whole screen turns to another color.
       
      This is the final configuration:
      AAPL,ig-platform-id <0300220D> framebuffer-con1-alldata <02020A00 0100000 87000000> framebuffer-con1-enable <01000000> framebuffer-patch-enable <01000000> This is the video proof:

      Hello people,
      I'm having trouble enabling the battery status. I already installed Kext ACPIBatteryManager and tried to apply a ready-made RehabMan patch for Dell models, the patch compiles without errors but does not correct the problem.
      The percentage is stuck at 99% and the icon is as if it were charging, Can someone help me?
