Laptop not booting, no beeps, no fan

My HP Envy 15 Laptop (Model Number 15-ae170nz) just stopped working without any prior issues. When I try to boot it up all that happens is that the light on the power button goes on for about 5 seconds, but there are no beeps or fan noises. Previously it was working fine, I put it to sleep normally and when I tried to boot it again it was like this.

I opened it up and found a loose screw rolling around inside… I tried removing battery, ssd and RAM without any effect.

Any ideas?
