The screen bezel on a laptop is designed to cover the edges of the LCD display, hide cables and provide an aesthetic appearance to the display. Mechanically, these bezels are usually simple and are nothing more than a rectangular piece of plastic that's screwed into the display frame and backing. As it is nothing but fairly thin plastic, a bezel can become cracked or chipped fairly easily, even from a fall that doesn't damage any other part of the laptop. Fortunately, repairing or replacing the screen bezel for most laptops is a fairly simple procedure that can be done by anyone.
Before performing any maintenance on your laptop, turn it off. Disconnect the power supply and remove the battery. Open your laptop and place it so that the screen is facing you.
Examine the edges of the screen. You are looking for small plugs at the edges of the bezel, or more rarely screws. Most laptop designs use rubber feet or small plugs to cover the screw-holes on the bezel. You will need to remove and set aside any plugs you locate. If you cannot remove them with gentle finger pressure, use a thin blade to carefully pry them loose.
Remove all visible screws from the bezel with the Phillips screwdriver, being careful not to strip them. Set the screws aside.
Remove the bezel from the LCD screen backing. Most bezels can be removed by gripping their inner edge where it touches the screen and pulling it away with a rolling motion. Multiple plastic tabs are used in addition to screws. Pulling from the inner edge releases these tabs.
Examine the bezel for cracks and chips. Small cracks can mended using superglue or epoxy. Be sure to allow time for the adhesive to fully set before reattaching the bezel.
Line up the repaired or replacement bezel with the LCD frame and screen backing. Press the bezel against the backing with a steady and firm pressure to re-engage the plastic tabs. Pinch the bezel between a thumb and forefinger and slide your pinched fingers from one end of each side to the other to ensure that all tabs are hooked.
Replace all the screws using the Phillips screwdriver.
Replace any plugs that cover the screw holes.
Use an empty medicine bottle or other container to store the screws from this repair when they aren't needed.
Before attempting to remove the bezel, verify that you have removed all of the screws. If, during removal, you find an area that resists separation, verify again that you have removed all of the screws and check for any covered screw holes that you might have missed.
