I've been using my Acer aspire 5 (2021) for almost a year now and nothing has happened until yesterday when I tried to power it on. The first thing I noticed was that when I pressed the power button, it didn't immediately turn on. I had to wait for a couple of minutes before it showed signs of powering on. Second is that the first time I tried opening it, it managed to get to the sign in screen but it kept sleeping and turning back on and the option to slide the screen in order to shut it down kept appearing (that's when I thought that maybe it might be a power button issue) I tried restarting it, but after doing that, the laptop just powered off at the Acer logo screen. Now, the day after I tried to power it up again but this time it can't even properly turn on. The keyboard backlight turns on for a few seconds and then the laptop turns off.

There's another reason why I think that it's a power button issue. There was an instance where the laptop tried to diagnose itself but then a screen popped up saying that I shouldn't shut down my laptop even though I wasn't pressing the power button.

Is there a solution to this? My school works are still in there and I need it in 4 days
