What is shown in SysPrefs -> Displays?

BTW, your DSDT has quite a few _OSI checks (checking the OS that it is running under). Might be worthwhile fixing some of that. Most examples I've run into have the DSDT do the same thing it does on "Darwin" as on "Windows 2006" (Windows Vista). If you were to replace all instances of "Windows 2006" in your DSDT with "Darwin" that would be the effect.

FYI: patch for that would be:

Code:

into_all all code_regex \"Windows\s2006\" replaceall_matched begin "Darwin" end;
into_all all code_regex \"Windows\s2006\" replaceall_matched begin "Darwin" end;

I'm not sure why it has to be done twice, but it does... probably a bug in MaciASL.

see attached, for displays, that display shown is the HDMI. detect displays doesnt find anything. ran the patch and will reboot.

That's what I was wondering about... whether it was detecting the internal display at all. Sounds like not... Your DSDT definitely has a lot of checks for "Windows 2006" (it is one of the more bizarre ones I've seen) so be sure to try that...

thanks rehabman, i ran the patch and it did replace the windows entries, still same behaviour though, the builtin lcd still is disconnected once the login window comes up...

I wonder if it could be EDID issue. Really don't know at this point. You might look at injecting EDID for your display with AAPL00,override-no-edid (placed in _DSM method for GFX0 device).

It would look like this:

Code:

            "AAPL00,override-no-edid", 
            Buffer (0x80)
            {
                /* 0000 */    0x00, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0x00, 
                /* 0008 */    0x30, 0xAE, 0xB2, 0x40, 0x00, 0x00, 0x00, 0x00, 
                /* 0010 */    0x01, 0x13, 0x01, 0x03, 0x80, 0x22, 0x13, 0x78, 
                /* 0018 */    0xEA, 0x21, 0x35, 0xAD, 0x50, 0x37, 0xAA, 0x24, 
                /* 0020 */    0x11, 0x50, 0x54, 0x00, 0x00, 0x00, 0x01, 0x01, 
                /* 0028 */    0x01, 0x01, 0x01, 0x01, 0x01, 0x01, 0x01, 0x01, 
                /* 0030 */    0x01, 0x01, 0x01, 0x01, 0x01, 0x01, 0x4C, 0x36, 
                /* 0038 */    0x80, 0x82, 0x70, 0x38, 0x32, 0x40, 0x3C, 0x30, 
                /* 0040 */    0xAA, 0x00, 0x58, 0xC1, 0x10, 0x00, 0x00, 0x18, 
                /* 0048 */    0x3F, 0x2D, 0x80, 0x82, 0x70, 0x38, 0x32, 0x40, 
                /* 0050 */    0x3C, 0x30, 0xAA, 0x00, 0x58, 0xC1, 0x10, 0x00, 
                /* 0058 */    0x00, 0x18, 0x00, 0x00, 0x00, 0x0F, 0x00, 0xD1, 
                /* 0060 */    0x09, 0x32, 0xD1, 0x09, 0x28, 0x1B, 0x19, 0x00, 
                /* 0068 */    0x06, 0xAF, 0x56, 0x34, 0x00, 0x00, 0x00, 0xFE, 
                /* 0070 */    0x00, 0x42, 0x31, 0x35, 0x36, 0x48, 0x57, 0x30, 
                /* 0078 */    0x31, 0x20, 0x56, 0x34, 0x20, 0x0A, 0x00, 0xD6
            }

You'd have to substitute your own EDID data, of course...

thanks i'll see if i can figure that out, at least i got my w7 cloned back onto this now so i can boot to it to check out the hardware.

i'll report back what i find.

thanks!

Also one other thing we do with the ProBook that might affect things... renaming GFX0->IGPU:

Code:

into_all all code_regex GFX0 replaceall_matched begin IGPU end;
into_all all label GFX0 set_label begin IGPU end;
into_all all label _SB.PCI0.GFX0.DD02 set_label begin _SB.PCI0.IGPU.DD02 end;

Also, check... is your laptop a dual-graphics device setup? (I see signs in DSDT that could be the case). Make sure switchable graphics AMD or nvidia are disabled in BIOS.

It's only single, no other gpu's. i've gotten my edid from windows and think i can put it in place, questions i have about this, would i change the Buffer (0x80) from your sample to something different? also your sample has 8 columns of edid and mine from windows has 9 columns of data. add all the columns im guessing? here is the edid if it helps to see what im talking about.

i've found some postings on the web about edid causing lcds not to work so maybe this is on track.

Columns don't matter, just the 128 bytes:

Code:

  "AAPL00,override-no-edid", 
  Buffer (0x80)
  {
  0x00, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0x00, 0x36, 0x7f, 0x03, 0x90,
  0x08, 0x00, 0x00, 0x00, 0x00, 0x15, 0x01, 0x03, 0x80, 0x1f, 0x11, 0xff,
  0x2f, 0x00, 0x00, 0xa0, 0x57, 0x49, 0x9b, 0x26, 0x10, 0x48, 0x4f, 0x00,
  0x00, 0x00, 0x01, 0x01, 0x01, 0x01, 0x01, 0x01, 0x01, 0x01, 0x01, 0x01,
  0x01, 0x01, 0x01, 0x01, 0x01, 0x01, 0x3f, 0x1b, 0x56, 0x80, 0x50, 0x00,
  0x26, 0x30, 0x36, 0x16, 0x36, 0x00, 0x35, 0xae, 0x10, 0x00, 0x00, 0x18,
  0x00, 0x00, 0x00, 0xfc, 0x00, 0x31, 0x33, 0x36, 0x36, 0x78, 0x37, 0x36,
  0x38, 0x0a, 0x20, 0x20, 0x20, 0x20, 0x00, 0x00, 0x00, 0xfd, 0x00, 0x00,
  0x3a, 0x00, 0x5e, 0x07, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
  0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
  0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x95
  }

BTW, all I did was copy the EDID hex bytes, remove the 'offset column' ('000 |', etc), then pipe it through xxd:

Code:

# in Terminal
xxd -r -p <edid_cleaned.txt | xxd -i
