You may be able to fix it with some very fine soldering. If you post one or two close-up photos of the break, any other buttons or LEDs supplied by the same ribbon and the socket the ribbon connects to we may be able to advise better.

Or maybe you could get a "spares or repair" laptop of the same model cheaply on eBay and replace the whole palm rest.

BloatLers to repair this you can replace the power button board and flex cable. Here are the instructions and the replacement part is available at places like this and many more.

Unless you have a board schematic which would show what pads are responsible for the power on state, you cannot turn it on without replacing the defective parts.
