Friends. I beg you to help me in this situation.
Lenovo X240 with a video problem. Native Intel drivers are not installed,
after installation, a black screen. It works with the standard Microsoft driver.
Understanding that there are problems with the video core,
I ordered a motherboard from Lenovo X250.
The laptop turns on, starts up, there is no image on the internal display.
The image is output to the external monitor.
I ordered another motherboard from Lenovo X250.
The laptop turns on, starts up, there is no image on the internal display.
