Replaced Laptop Motherboard, Won't Turn on Now...

[Joey Zhang]

Hi all,
I recently replaced spilled water all over my laptop. I make the mistake of not waiting for it to completely dry and attempted to turn it on.
So after, accessing the damages, I took my Lenovo Y50 to a certified technician who told me that the motherboard was damaged. I decided to replaced the motherboard by myself (purchased Lenovo refurbished from Ebay) and proceeded to install it.
When I turned it on, the LED lights up to signal that it is being turned on, however the fans do not start, my keyboard does not light up, my display does not turn on. (Basically, only the power button LED turns on for about 2-3 seconds, then shuts off)

1. I made sure the ram, harddrive, thermal paste, screws, cords etc was installed properly.
2. When I charge my laptop, the LED lights up to signal that it is charging.
3. I attempted to turn on my laptop without the battery, to this I received the same 2-3 second LED and nothing more.

Does anyone have any recommendations of what is wrong with my laptop?
Can we narrow it down to a specified region?
Thank you for your time guys, I really appreciate it.

I can't comment from experience, but I think I've read or heard about this somewhere in the past. I think somebody got a solution by disconnecting a switch for the lid, as it was constantly thinking the lid was closed. Just a thought.

Edit: Found the forum post I read here unique situation, so not sure if this'll help you out at all, but worth a shot.
