MacBook Air will not turn on

So my MacBook Air will not turn on. It is the 2015 model. I used it in the last few days, and then shut the screen (didn’t turn it off - just shut the top). Went to use it tonight and there is no sign of life. The charger has turned from orange to green now so I know that the battery not charging isn’t the issue. The trackpad is still clicking so I know the laptop hasn’t completely died. There is no chance of water damage or anything of that sort. It is also not the display as when I flash a light at it the screen is still pitch black. When I try to boot it there is no noise at all from a fan, the pinging noise etc. A lot of common solutions for a lot of people haven’t been working for me. Going to phone Apple tomorrow and see what they say, but I don’t really want to be fined hundreds for something I could possibly fix myself. I don’t really feel comfortable opening it up tbh so is there any solutions that have worked for anyone here?

So update, in case anyone in future sees this who’s having the same issue I was. I knew the laptop hadn’t completely died and so with the help of a YouTube video by “Berry Meherg” called DIY Macbook won’t turn on, I realised the issue was the battery. When I disconnect the battery and have the laptop on charge, it works again. So just going to order a new battery to replace it hopefully
