Dell 13Z Power Button Issues / Mystery ???

My Dell 13z has a problem starting back up from sleep or full shutdown. Most times when power button is pressed, it lights up along with the power led and 3 lights in top right corner sequence and that's it. NO HDD Light and No screen. If I press the button again it will turn everything off. This takes 10 or so times to get the laptop to turn on correctly and full function.

It seems like I have to push the power button a certain way to get HDD and Screen to power up. ??

I pulled power button assembly out to check and there is only 1 button in there. Could this be defective in some way?
