Solved Blank Screen after Transcript Offline on IntelHD3000

^^ Great advice indeed. Mald0n is a very helpful guy. BTW, does your fresh DSDT (without any edits) compiles successfully ?

My fresh DSDT does compile correctly. I get errors when I add the code under gfx0. If I add the code under the other video devices, I don't get errors but nothing happens.

You should manually type the code & not copy-paste from here.

Also make sure the commas, braces are at right places. And use DSDTSE. Text editors insert hidden characters causing errors.

Can you add your freshly extracted DSDT (which compiles) in attachment? I'm not that much of an expert but I'll have a look

Hi pauldmps, I realized this fix got my HD 3000 working with full res on my internal laptop display but without QE/CI. Any idea to solve it?

Tried new Chimera (v1.5.2) already ? It works like a charm over here

Yes, after work today I will send it to you. Thank you so much.

Just adding the _DSM method throws up about 150 errors.. Haven't seen anything like this before...

No matter what I try, I get errors. Even simple fixes like brightness correction on display wake-up give me errors. When I add the dual link correction, I get 6 errors.

1. Check "Extensions" in system profiler to see if "AppleIntelSNBGraphicsFB.kext" & "AppleIntelHDGraphics.kext" are both loaded.

2. Check that if you get "SNB Framebuffer did not show up, unload" message when booting with -v (verbose).

Also I need to know the DeviceID of your HD3000.

@lightmanrt

I analyzed you DSDT. It is hell a lot buggy. The stock DSDT gives 13warnings - not good. Also most of the warnings are "statement unreachable" which according to me is causing problems when code is added there.

Also your GFX0 has no info which should be present there. And both IGP & PEGP are missing. Very weird.

First of all, check if there is any BIOS update available for your laptop. If yes, update your BIOS & extract a fresh DSDT.

I'm not sure that your IntelHD is under "GFX0", it could as well be under "IGP" or something else.

Save a IOReg dump & attach it here.
