Введение

If your Lenovo N23 Chromebook’s screen has defects, glitches, or is broken, follow this guide to replace the screen.

The screen is the main display of the laptop. It allows the computer to take computer outputs and display them in a way that we can see and understand. A faulty or broken screen will have blemishes, visual glitches, or wont be able to turn on at all.

Before using this guide, try rebooting the laptop. Sometimes some video glitches may happen that can be resolved with a hard restart. If the laptop still does not work correctly, that indicates that there may be a problem with the screen.

No special skills are required to follow this guide.
