Chuwi Hi10 Air stops charging and flashes white and then stops see pictures

Since yesterday I had 30% and worked on the laptop while I was charging it. The laptop didn't charge properly… It charged for a second, then no more, then it charged again, then no more… That drove me crazy, so I unplugged it and took advantage of the 30%. Then my laptop was empty after a while and I then closed it on the charging cable and it stopped charging at all! I used other Huawei charging cables and it didn't charge anymore! While I connected the different charging boxes and pressed the top button, he didn't turn on either. No logo, nothing… So far it's still like this, doesn't come on… And when I plug in the charging cable again, it just blinks and goes away and so on…

What do I do now? What was the mistake How do I fix it?

Have you tried another outlet? Maybe the port is broken.

Yes, I have too. The laptop does not work with all sockets. Any idea what could be the reason?

Is this a removable battery?

No, unfortunately not. Not removable, is integrated into it…
