I'm not familiar with the MAC's, but on the Dells you can just replace the keyboard. Just search for the model number on eBay and find a seller with the parts. They are cheap at some places and some are more expensive. I've changed several over the years and it is a very easy repair.i need to do this for under the keys to my macbook pro, there are already led segments under the keys but a column of them are dead and i'd like to get a nice red illumination rather than the boring white
anyone know a guide how to dissect a unibody macbook keyboard and insert new lights??
