RE: Black Mark

Hi sulav,

Please run the “LCD Test”, follow the steps below.

Switch off the computer > Press and hold down the ‘D’ key on the keyboard and press the Power button > you will see different colors on the LCD screen. During the LCD test please check if the black mark appears?

Also connect an external monitor and check if the issue persists.

Thanks and regards,
Senthil S

RE: Black Mark

If it shows on an external monitor, replace the video card (or mainboard if the chip is on the board).  If it does not, replace the display panel.
