In the case where your Lenovo N21's screen is cracked, malfunctioning, or not working at all, you may need to replace the screen. This can be done easily by removing the protective panel around the screen and removing a few screws. Be careful when pulling away the screen's protective panel, because bending it too far may cause it to snap.
