Turn off your computer through the operating system. Unplug all cables and external devices from the laptop. Remove the battery pack from the bottom of the laptop. The battery pack is usually held in place by one or two release buttons.
Pull open the display panel all the way. Use a thin, flat-head screwdriver to pry the rubber screw covers from the laptop's front bezel, which is the main plastic piece on the front of the screen. Remove the Phillips-head screws from the bezel, and remove the bezel from the display assembly with your fingertips. You may need to use a flat-head screwdriver or guitar pick to completely remove the front bezel from the laptop.
Loosen and remove the Phillips-head screws from each side of the LCD screen that fasten the screen to the metal frame inside the display panel. Grasp the top edge of the LCD screen, and tilt it forward. Unplug the LCD video cable from the connector on the back of the screen. Peel away any tape that secures the LCD cable to the screen. Lift the broken screen out of the display panel, and throw it away.
Place the replacement screen inside the display panel. Connect the LCD video cable to the connector on the back of the screen. Secure the cable to the back of the screen with a few small strips of electrical tape. Line up the screw holes on the new screen with the screw holes on the metal framing inside the display panel. Fasten the screen to the display panel with the Phillips-head screws that came with the replacement screen.
Place the bezel on top of the newly installed LCD screen, while aligning the screw holes on the bezel with those on the display panel. Replace the bezel's retaining Phillips-head screws, and the rubber screw covers. Replace the battery pack, and reconnect all cables to the laptop.
