I've taken apart this laptop multiple times but after putting it together today, it will not turn on or show any indication of power. I messed up something but I'm completely unsure of how.

Laptop model is a Predator Helios 300.

Mistakes I've made that could have contributed:
1. I forgot to unplug the power supply before taking it apart; This has happen once before but did not cause any issues.
2. Cleaned with a napkin; Same as above.
3. I accidently touched the board once or twice with my hands.

I've checked every connnection. I'm unsure on what to do next. Any help or advice is greatly appreciated. Will post pictures for reference.
