MacBook Pro not turning on

This morning, I was running MATLAB on my Macbook Pro, and then the screen froze for about 5-10 seconds then proceeded to go black. Afterwards, I could not power on my MacBook.

I opened it up and saw that the battery still worked and some portions of the logic board were warm (after about 2 hours). However, no matter how many times I pressed the power button, the fans would not spin nor would any lights turn on. I watched one  of Louis Rossmann's videos and tried to diagnose the issue, but the PPbus to SSD didn't seem to have an absurdly low resistance.

I do not recall spilling liquid or dropping it, so I assume that the SSD was fried, but realized that may not be the case.

May I get some professional diagnostic before I go ahead and recycle the laptop?

Sorry, there’s little we can offer remotely here. All we can offer is guidance in you repairing your system.

Deeper issues like you appear to have requires tracing out the logic. Here a good inspection of both sides of the logic board looking for damaged components as well as checking the power rails.

You’ll need access a set of schematics and board view drawings. Micro-soldering tools and skills.
