Acer Swift 3 Power Problem?

I received this Acer Swift 3 Laptop on December 17, 2002. Since it's a holiday, I've only used this laptop once a week for a few hours.I have no idea what happened to my laptop. When I try to turn it on using the power button, nothing happens, but when I click the keyboard on my laptop, it turns on, but when I stop tapping on the keyboard, it shuts down again. Is there anyone here who can assist me with this problem?
