Question Lenovo Thinkpad E15 Beeps with infinite Restart loop

[Fullen1st]

Hello guys,
I lately spilled some water by mistake on my Lenovo Thinkpad E15 keyboard ( Power supply side ) and it started doing some beeping ( 1 Short 1 Long beep ) everytime I turn it off and on and it keeps on restarting ( Note : Black screen, and only the lightbutton going on and off ) without the beeping going away, it doesn't wanna shut down and it doesn't wanna start up, when I hold down the power button, the beeping sound changes into 4 beeps, when I let go of it, it goes back into the old beep. After a while it starts up finally and after a hardware scan using the Lenovo Vantage + Lenovo tools, I don't find anything damaged ( All components pass the tests ). Any idea what would be the problem ? If anyone can help I would be really grateful, thank you in advance.

The main board has been fried in a short sense of the topic, it is having a issue with controlling all the components due to a voltage short in probably the soldering

what makes it capable to finally be able control the components for the computer to actually start up ? i didn't think it would be able to with a fried board, as well as I didn't think that it wouldn't show up on the diagnostic. And if it's really fried, the only fix would be to change it right ?
Adding to what I previously said, I forgot a detail which is : The ports from the side where I spilled water + keyboard during the loop don't have power but the ports on the other side from the spot do get powered up (used a mouse with lights to check, it turns on on one side, but not on the other)

Yes you fried part of the mobo circuit it's probably a none key, key component of the system. So the computer is bypassing whatever is causing the short and it probably actually won't show up as a problem due to the main power point of the issue is being cut out so the diagnostics tools don't even see that it's actually there
