T410 - egpu detected but not working

Hi,

(sorry for my bad english)
i already post but i think it was not the right section:

---------------------------------------------------

i need help to install the driver for my egpu, a Gtx 560 Ti

my stuff:

lenovo thinkpad t410
core i7
8 gb ram
win 7 64x
igpu nvs 3100M

I have a display connected to the egpu.

The egpu is detected i have vga standard with error code 10

when i uninstall all the graphics drivers and install the nando4's it don't ask me to install twice. When the installation is finished, only the internal gpu works and the egpu is no more detected (the fans turn faster) and the computer go slow.

Each times i install nvidia driver, it overwrite the other already installed: egpu's driver overwrite the igpu's and the igpu's overwrite the egpus.

when i uninstall all the graphics drivers and install only the driver for the egpu the display still black (and i have no more error or yellow warning like code 10)

the gaphic card works on a PC.

I have the PE4H v2.4.

I see that one person suceed the installation on a t410:

Hello

nobody can help me?

i think the first things is why it doesn't ask me to install twice the modded driver as you say on the forum for the igpu and gpu nvidia

if nobody can help me it would be nice if i can have the email of the person who succed with the lenovo t410 or juste make en pm but there is no option for that.

 

hello

i didn't touch the CN9 yet (12v by fuse or bybasse) (on the pe4h v2.4). The circuit is open. Must i change this?
