Studio 1535 need to replace power button

My laptop fell on it's corner and slightly cracked the corner at the hinge where the power button is. The laptop will still power on via the media center key, and as best I can tell all the wires are still connected to the power button, I just can't push it in to turn the pc on. It still lights up when the computer is active. Would I need to replace the whole thing ( I've read in other forums this may involve soldering it to the motherboard) or is there somwhere I can access a diagram of how the button needs to be situated so that I can push it in? In the meantime, is there another way to wake this laptop up from sleep besides pressing the power key?

Thanks!
