Macbook pro 2019 16" not starting up

My Macbook Pro 2019 16" was working normally. One night I put it to sleep and laid it down on the nightstand. The day after (today) upon opening the lid nothing happened. I try hard resetting the Mac and heard a hard fan blow...

Since then nothing happens. I tried with charger plugged it, left it a few minutes, nothing at all .. the fans are not spinning, it feels like there's no juice in it despite charging for 2 hours straight.

- No screen, no feedback, no sounds.

Any ideas?

MacBook Pro 16″, macOS 11.5

Update:

yesterday:

I tried a lot of things... Even looked inside whether some component was not unplugged or something. Only some dust which I blew with pressurized air. Still nothing. Despite trying with charger, without the charger, etc. The fans did not start spinning, nothing was booting. I tried the following key combinations even:

Option-Command-P-R: Reset NVRAM or PRAM
Option (⌥) or Alt: Startup to Startup Manager
Shift (⇧): Start up in safe mode
BUT NONE OF THIS DID ANYTHING, SINCE "no power" ran through its 'viscera'

Today:

I came to work and plugged the device into a USB hub I use at work (i-tec https://i-tec.pro/en/produkt/catriple4kdockpd-2/ )... All of a sudden, the device turned on almost immediately and runs without issues... The values of my setups at work and home are as follows:

Home:

230V / 50Hz - wall outlet
No dock - only USB hub (HyperDrive 3v1 USB-C Hub 4K HDMI - Space Gray) -> USB Mouse + 1080p Monitor
96W stock adapter

Work (Dock)

230V / 50Hz - wall outlet
Dock https://i-tec.pro/en/produkt/catriple4kdockpd-2/ - NO Mouse, Ethernet cable plugged-in, 2x1080p displays plugged in, 85W power delivery (USB-C)

Is there something you recommend doing now, since it runs? Maybe try reset the NVRAM or PRAM now? Are there any logs that I could look through so as to potentially find something peculiar about the case?.

Thanks in advance
