Thank you for your response, Since this is the Laptop computer and you’ve mentioned previously the screen flickering happens when opening and closing the laptop lids it might be the LCD cable is loose or not connected properly and in order to fix the same we had provided the manuals so you can open the laptop and reseat the LCD cable accordingly. In case you’re not comfortable doing the same and if your computer’s under warranty please provide us the Service tag of your computer on a private message so we can check your computer.
