My MacBook Air does not turn on

Hi guys. I but a MacBook Air 2019 just 3weeks ago. Last night after working with it, I quit all the programs and closed the lid (it has 80% battery). Today when I opened the lid, the screen turned on without showing anything and suddenly off! I tried power bottom, pressing power bottom for 10s, control+option+power but non of them working. Last time I tried command+option+p+r technic but it did work. What should i do??
