2018 Spectre x360 15.6" - Motherboard issues?

[EddyP0]

I own a 2018 x360 spectre 2-in-1 that has suddenly stopped working. 

I get no charger indicator light when it is plugged in (I have tested with two known good chargers) and nothing has seemed to help.

I've tried all of the steps I was able to find: unplugging the battery & draining the caps, BIOS reset, replacing the AC input cable and jack.

At this point I am out of ideas and options I feel comfortable with trying myself. 

After removing the SSD to retrieve my files (approx 1 month after I had given up hope) the computer turned on successfully one last time while the SSD was removed. 

Does anyone know what this may point to? Can a bad cap come 'alive' once more after resting and does this help to narrow down my potential issue? 

Also, what does a replacement mobo for this device cost?

Thanks for your time and assistance!
