Any idea why is that happening?

Thats what happens when I try to turn my laptop on

Sorry if I'm posting it here instead of taking it to someone whos specified at fixing techs but as some of you know, I recently moved to Italy and I don't speak Italian very well yet and I have no one as a (translator) nowadays so it'd be appreciated if you inform me about the exact problem if you know or ever faced this problem

Note: My laptop's battery was always kinda broken, it never used to turn on if its not on charger and it has been working like that for years.

Thus, I ordered a new battery for this laptop days ago and it is arriving in couple of days, I hope it is the solution though

Thanks in advance!
