Hi mostafa_gamal , 


Welcome to the Community Forums. 


Flickering and the dark area at the bottom of the screen usually are symptoms of LCD panel issue.

We would assume that connecting the laptop on external monitor have a good display but same issue would happen in the BIOS.


You may call in tech support for in warranty service.

Else if panel needs replacement, you may check the part number from the parts look up page and service locator for the repair center.
