How do I get my laptop working again?

Go
7

It looks like this all along:

everything black and in the middle it has been charging for 10 minutes

De

Everything black and in the middle it has been charging for 10 minutes

If everything is black, then there's nothing in the middle either.

Just keep the power button pressed until it has switched itself off completely and then restart.

Go

That doesn't work I've already done

De

Then start in safe mode (F8)

Go

How do I do that? I just press f8

De

Yes, press F8 several times in succession until he has accepted the key and can start in safe mode

Go

How long should i do this

De

Press several times when booting until the prompt appears. Should not take longer than 1 minute
