Remove the laptop battery before disassembling the laptop.












Remove the screw-covers from the front of the screen. This is where you will find the screws holding the front plastic to the laptop.











Unscrew all the screws after removing the covers and keep them aside.













Next will be to put your fingers between the screen and the plastic bezel and start pulling on all sides.












Pull on all sides until the bezel starts releasing from its catches. This pull must be done firmly but with care to avoid snapping the plastic.











Now that the internal part is exposed pull the screen slightly towards you and remove all side screws from the brackets.







Place the screen face-down as in the image on the left. Now you will be able to see the display cable and the screen part number.

Part numbers like LTN156AT18, LTN156AT19, N156BGE-L52, or N156BGE-L62 is likely be on the sticker on the back of the screen. These numbers can also be used to order the screen from any seller. The mentioned laptop screens are very much compatible and interchangeable.







The last thing to do to remove the broken screen is to disconnect the display cable. NOTE THAT THE CONNECTION IS HELD TOGETHER WITH A CLEAR TAPE. Peel up the clear tape before disconnecting.




To install a new screen simply continue the process in reverse.
