Please only answer who really knows.

Hello, I just played a bit on the laptop.

Suddenly the whole screen turned blue and in the middle stood "lock"

He drove off by himself and if I want to make this

If the light flashes, but he makes no more sound.

I have ten windows

What can I do now?

Was my laptop possibly hacked?

Start in safe mode or try it?

Ca

He does not start anymore.

Hmm, then sounds very much that the screen / graphics card is defective… Hacking has nothing to do.

Due to the word lock, I assume that your parents have set a usage limit on the notebook. Windows offers this feature. I can't tell you how deep that is.

Your parents have probably installed a time-limited child lock.
