My zif connecter on the motherboard, for the power ribbon, broke.

ny jumpering on board will be appericiated?

That Zif connector just holds the ribbon cable in contact with pins. You can try cutting off a sliver of plastic from a credit card and wedging it in there to hold the ribbon to the connector. I have done this with my laptop when the zif socket for my keypad broke. It takes a very thin piece to do so. Then take some captons tape or other electrical tape and place it over the socket to ensure it stays.
