Power on issues - Compaq presario 2100 Laptop

I have a Compaq presario 2100 Laptop. Recently I had a dim display, so in an attempt to repair I disconnected the connector for the LCD display from the Mother Board and reconnected. When I put the thing back together it would not power up. I rechecked everything, it was put pack properly. I had stripped the laptop on several different occasions without a single problem.

1. Is it possible I shorted out the Motherboard. If so, is there any way to check.

2. Also what is the part called, the strip the the power button cover snaps over, that is screwed down under the speaker assembly. Is it possible this part was shorted out.
