Replaced Motherboard on Lenovo Y50, Why won't it turn on?

by DumplingZhang / May 26, 2015 3:45 PM PDT

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.

Why did you change the motherboard instead of just use the computer you bought from ebay?

it it was not the exact same motherboard, you will need to reinstall the operating system. different motherboard, different drivers.

There are some extra parts to narrow it down.

I can install one stick of ram, leave out the HDD, ODD, KBD and try again. But I fear this only reduces it a little. Refurb laptop motherboards? You may have better odds in Vegas.

Call the tech and have them take the entire laptop to pop in a good working board.

then the only thing left to do
by James Denison / May 27, 2015 5:17 AM PDT

is check your hookups again, and BIOS settings. You can access the BIOS??? It's the most basic first step in dealing with a replaced motherboard, so if you can't get past that step, then you either have another bad board or a power supply problem (battery, charger, or both)
