How to Fix a Broken Laptop Screen?

Depending on what specifically cracked on a laptop screen, there will be different visual issues.

Restarting should be your first option because it's so simple to do.

If the screen occasionally turns on and occasionally doesn't, your lid sensor is definitely damaged.

Try connecting an external monitor if your screen is completely black.

Try updating your video drivers if you observe visual flaws on the screen but your screen isn't completely black.

A cracked screen is also another sign that you need to replace it.
