Laptop won't boot, Blinking Caps Lock key

[JV125]

Hello,

I've been using my laptop (Victus by HP Laptop 16-d0430nd) for a while now and after some mild performance/heating issues I decided to carefully clean the fans and any other dust that may have built up today. After putting the case back together the laptop does not boot anymore. The light of the power button will turn on when pressed, and the light from the caps lock key will blink four times. After the last blink, which is cut off and shorter from the first three, the lights and fans will turn off. 

I've tried some suggestions I came across online. I tried cleaning the RAM compartments and attempted booting with a through a charger with a  disconnected battery, which turns off even faster without a blinking key, but to no avail.

Any ideas to get my laptop working again?

For anyone coming across this post in the future with the same problem: brought the laptop to a repair shop and the told me something on the motherboard was just broken, likely from overheating, and the laptop would indeed shut off before the full Caps Lock code could finish. The cooling system had quite a bit of dust in it still. Sucks :(, warranty just expired too. Be sure to clean your laptops!, I guess
