Toshiba Tecra S10 internal LCD Screen stays black

hookme · March 5, 2017

Hello community,

after several days trying to get the internal LCD working i have to ask you.

But the first here are the specs of my opponent :-) :

Toshiba Tecra S10 ( Toshiba S10-106 / PTSB3E-00C006GR)

Cpu Intel T9400 Processor

Nvidia Quadro NVS 150m Graphic 256MB

Chipset Intel PM45 Express

Displayformat 16:10

Screenresolution WSXGA+ 1680x1050

http://www.toshiba.de/discontinued-products/tecra-s10-106/

So far:

After patching the org DSDT i can get the VGA-Output up and running (QE/CI is running, all resolutions of the Monitor are selectable and useable ; tested with two different Monitors).

I achived this by just renaming the Device unter Device PCI0-> Device PCI1 -> Device VGA into PCI0-> Device PCI1 -> Device AGP and inserting a new Method _DSM which i found somewhere. Some Thinkpad T61 an Dells D830 do have some similar graphics (NVS140M or NVS135M) and got these full running - so that motivated myself a lot.

But the i can't get the internal LCD running with this method. To get the internal LCD-Screen working i have to boot with nv_disable=1. What do i oversee or miss? OS X is Mavericks 10.9.

I will attach the extracted orignal DSDT/SSDT with Clover. With Windows i was able to extract the EDID-information of the Laptopscreen, just in case in will be needed.

Maybe someone can point me in the right direction or do have a solution for my problem. If i missed information you would need just let me know.

Many thanks in advance.

Hello artur,

thank you for the fast reply but sadly it isn't working - the screen stays black. BUT i got it working. Please let me explain how i achieved this.

Firstly i tried to rename the Device PCI0-> Device PCI1 -> Device VGA into PCI0-> Device PGEP-> Device GFX0. After that i just inserted your _DSM Method - but the result was the same as before: External VGA Yes; Internal No.

Motivated thrue this post http://www.insanelymac.com/forum/topic/111271-discuss-8400m-gt-for-vaio-only/page-4?do=findComment&comment=2164952 i have decided to adapt this. I have inserted the Method _DSM and exchanged the EDID Entries i have got true Windows. As result the internal LCD ( with all its resolutions is) fully working with QE/CI. Even a monitor can be used at the same time - with its own setting! (UPDATE: Brightnesscontrol fixed!)

artur_pt are the any other important fixes i have to do, like ~~Brightness slider,~~ or other optimized DSDT things? Now i have two big topics left: Powerbutton (isn't working) and a working sleep.

So many thanks and thanks in advance
