NO POWER TO DV6 Laptop

Ok this laptop has been problem after problem, not the computers fault by mine. Anywho. last week I replaced the LED screen, pretty simple fix. Required a lot of dissassembly, but it was easy. Ok i have had a problem with the battery falling out if the laptop is not placed down softly enough. the battery kept on comeing out because a tiny little piece of plastic that holds it in, must have broke off. But last night the battery fell out while i was gameing. Now I cant get any power at all. It wont boot up even when plugged in. Did something get shorted when the battery fell out? why am i not getting any power to my laptop,, even when i plug it in, no indicator lights light up, the battery doesnt even warm up from it being charged at all.

 

would this be a mobo issue?

 

i took it apart and made sure the power connection is secured, and it is. so im not to sure what the problem is, so odd that the battery falls out, and then comp stops getting power all together
