Screen is black at login screen if display driver is enabled
- by Amir Rachum
I have a Lenovo x200 and recently its screen didn't work, so I took it to a repair lab. The guy told me they replaced the screen inverter. I powered up the laptop and the ThinkPad logo was shown, so I was happy. When I got home the computer would boot up, then instead of the logon screen, I got a black screen. Went to safe mode, disabled the display adapters, reset the computer, and I got a clean boot. Then I tried to reinstall the drivers, and it just led to the same condition. My video card is (from device manager): Mobile Intel(R) 4 Series Express Chipset Family.
Now my laptop works as I'm working with display drivers disabled, but without display drivers I can't watch movies, etc. Any solution to this problem?
Edit: I plugged in an external monitor and it works on it with display drivers enabled. However, it does not find the laptop monitor.
