My laptop display working only half portion

Hi @thomaskutty

Try connecting an external monitor (TV perhaps) to the laptop's HDMI port and check what the display on it is like.

If the display being seen on the external monitor is also faulty then there's a motherboard problem in the laptop.

If it is OK then there's a problem either with the video cable, video cable connection (at either end, LCD panel or motherboard) or the LCD panel itself in the laptop

Here's the owner manual for the laptop. Go to p.76 onwards to view the procedure to remove the display assembly. This will allow you to check the video cable and the video cable connections. If the cable and connections seem to be OK then most likely it is the panel.
