Asus Laptop not booting, but keyboard backlight flashes

Hi. I have a ASUS FX504GD Laptop(i5-8300H, 24GB RAM, GTX 1050, Asus BIOS 317, 250 GB SSD and 1TB HDD) . I had a keyboard dust and spill issue where if I press a key, say "7" it would type in "7mdk" sorta thing. I took it down and started cleaning.

While I was at it, I also reapplied the thermal paste. I have done all this before and it usually goes smoothly. But not this time.

I tried booting it but it didn't. I tried all the common fixes(Checking RAM, SSD, power button connections, battery). But still it didn't boot. No signs whatsoever. Fans didn't start up, no lights and display.

I tried draining out the charge from the mobo(by removing the battery and holding the power button for a min). When I plugged the battery back in, I was able to see a brief 5 second flash of all the keyboard backlights and the power button light. That was weird but still upon booting it, nothing.

Also, while plugging in the AC adapter, usually a light glows indicating my laptop is getting charged, but now there is no light.

Has the spill fried or short circuited the board? Well, I cannot see any burnt spots or smell anything weird.

What may have caused this?

I'm desperate. Please help me out.
