There is evidently a hardware problem, some hardware that is vital to the laptop's ability to stay turned on. It's impossible to say exactly which part has failed without having the laptop opened up and examined by someone who knows about such things.
You will have to take it to a laptop repair centre and ask them to have a look at it.
