Laptop not turning on, no matter what.

[Muhammad55]

Hi,

I own a Hp Probook 650 G1 and use it for gaming and anything bcz of serious upgrades.

My laptop is having some serious problems. One day i came home from after 2 weeks and what i saw that paint rinsed water was spilled under my laptop. Spilled on side of table, then reached the base of laptop. I took out the battery and let it dry for 2 days. With fear of turning it on and having a spark, 

I carefully disassembled it after watching 7 videos, took out the base enclosure and washed it bcz it also had dried up paint.

After assembling it, i turn it on and it shows the lights on the power, volume button but shuts down without showing anything on screen. I took out the battery to see if i missed a connection inside, and after 5 min, i touch the battery and Its Hot! I quickly put it in my drawer in case it explodes. It remained being super hot for 3 hours without any connection. 

After that, i began inspecting the laptop again and found nothing, Also to be noted, it easily runs on direct power but in current situation it doesn't run on direct power. I tried it with another charger which is 90W (original is 65W), it took it a step further, now it shows Hp logo and turns off without even letting me access bios.

And the only way laotop turns on is by lifting the lid, power button is useless in current situation. I set "turn on when lid is lifted" in bios which is the only way it's taking affect.

I disassembled it again even further and saw no problem.

In total, i disassembled it 3 times.
