RE: Regarding laptop screen

Hi firozalam49,

To figure out if there is a problem with the LCD screen on your computer we will have to perform the ‘LCD BIST’ (Built in Self-test) on the computer. Please follow the steps mentioned below to run the “LCD BIST’.

  1. Turn of the computer.
  2. Press and hold down the ‘D’ key on the keyboard and press the Power button.
  3. You will see different colors on the LCD screen. Please check if the vertical or horizontal lines are appearing on the screen.

If you see the vertical or horizontal lines appearing on the screen while the LCD bist is running you will have to replace the LCD.

In addition, I would advise you to connect an external display and check for the issue.
