Won't boot

I've a Dell N5110 that got some water spilled into it.  Drying it out, it didn't do anything.  Replace MB as well as power jack board.  Now, what I get is blinking lights on power button and mobility display center button.  Does this reveal a service code or something?  Long pressing anything on the keyboard doesn't do anything.  Is there some hard reset combo I need to do?

I confess, this is not my laptop so I'm not so familiar with the details of its functions, although, by this time I'm intimately tuned in to taking the dam@ thing apart and putting it together again.  :pt1cable:

Any advice would be greatly appreciated.

Thanks
