Laptop locks itself and doesn't work anymore?

Moin, my sister just ran out of laptop with the message "lock". Since then it has not worked. I've already taken out the battery and let it cool down, nothing works. When I press the power button, only the battery indicator flashes orange briefly, that's it. My thoughts are that if it were the battery, it would have simply gone out or shut down and not locked. If the mainboard had said goodbye, the screen would probably have just gone black and it would have ended. So I don't know what the problem is. Maybe one of you has an idea.

Since the laptop has now reached its sixth year and wasn't particularly up to date at the time, I wouldn't be surprised if he just said goodbye.

Since the battery indicator flashes, I think that the battery got cracked by something.

Is it possible if a power supply is attached? It can also be that the laptop no longer loads.
