Acer Nitro 5 AN515-55-56R2 Charging But Not Turning On

Hello,

Our online class has just started and I really need to fix my laptop. It is charging but when I start pressing the power button, it won't turn on. Even I pressed it for 20 seconds or more, it's still not working. I used it last night but when I have to attend my online class it became like that and it annoys me. I didn't find any battery reset pinhole either. I hope you can help me solve this problem.
