How to fix laptop hardware / software problem?

Hello!

This is my laptop and the white and black have been there since this morning. But it didn't fall down. What can it be and how can you fix it?

The display is defective, you can't fix it.

What can you do besides buying a new one?

Get him fixed. But that can be just as expensive as a new one.

If you don't use it constantly on the go, buy a laptop instead of a laptop. On a PC, broken parts can be replaced more easily and if something is out of date (e.g. You can simply buy a new graphics card. This saves costs in the long run.)

Definitely take a PC / laptop with SSD

You can install a new DISPLAY
