i have a cf-53 toughbook that is now working except the LCD goes black after the apple.

HDMI out works just fine, but LCD is not recognized. I've looked all over and not found anything relevant-

any help would be appreciated.

We use this DSDT patch on the Probook, it may help you:
Code: 
#   Inject HDMI info into GFX0/IGPU   */
into method label _DSM parent_adr 0x00020000 remove_entry;
into device name_adr 0x00020000 insert
begin
Method (_DSM, 4, NotSerialized)\n
{\n
    If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
    Return (Package()\n
    {\n
        "AAPL,snb-platform-id",\n
        Buffer() { 0x00, 0x00, 0x01, 0x00 },\n
        "hda-gfx",\n
        Buffer() { "onboard-1" },\n
    })\n
}\n
end;

Use MaciASL 'patch' button to apply. Make sure you have an error free DSDT compile first.

Also, because you have Sandy Bridge CPU (because you said you had HD3000) on 7-series board, you need IMEI patch:

Code: 
into device label PCI0 insert
begin
Device (IMEI)\n
{\n
    Name (_ADR, 0x00160000)\n
    Method (_DSM, 4, NotSerialized)\n                
    {\n
        If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
        Return (Package()\n
        {\n
            "device-id",\n 
            Buffer() { 0x3A, 0x1C, 0x00, 0x00 }\n
        })\n
    }\n
}\n
end;
 
thanks, i will try that, it looks like chameleon wizard has a dsdt patching function (im using it to modify the chamelion plist, will this do the same thing as maciasl?

my first time having to patch things, my other hackintoshes have worked out of the box.

Almost all laptops require DSDT patches...

Use MaciASL. These patches are not compatible with Chameleon Wizard.
Patching DSDT is very different from making changes to /Extra/org.chameleon.Boot.plist.

Basic MaciASL instructions:

- download and run it.
- by default, if you have not patched your DSDT yet and installed it to /Extra/dsdt.aml, MaciASL will start by extracting your raw DSDT
- choose Compile from the toolbar
- if you have *errors*, fix them
- if you need help fixing errors, compress and post your raw DSDT.dsl
- after you have an error free compile, apply the patches with the Patch button from the toolbar (click Patch, paste patch text in, click Apply, click Close)
- use File Save As to save your result to /Extra/dsdt.aml, format: "ACPI Machine Language Binary"
- reboot and try.
- to boot without /Extra/dsdt.aml active, boot with DSDT=No at bootloader
 
great! thanks for the help. i'll try this all now and report back how it goes.
