Rewire the laptop power button.

Hi,

I have a desk and I've put  shelf on it that is 4 inches high from desk. On this shelf lie two 23 inch monitors. Below the shelf, tucked away, is my laptop (with the lid closed).

The problem is that I need to be able to turn the laptop on without opening the lid. (The power button is right above the keyboard). My motherboard does not support Wake on LAN but it does support USB Wake. This is a bit useless to me, however, because it doesn't allow me to fully shut down the computer, but rather put in stand-by.

So i wanted to know if there is a way to attach an external button (maybe a push switch) that can power the laptop? If so, can anybody help me out how to do it? I'd assume it would be in parallel to the regular switch. 

I have an Dell Inspiron 1521 (which I think is a fail to being with :P )

Thanks!
