help, 1st a recap. i had my powerbook g4 17" charging when i tripped on the cord and yanked it. the tip was broken off so i bought a new "refurb" ac adapter. it won't go in. inside the ac port is a metal part, i don't know if its from the ac adapter or part of the inside of the port that got loose, it won't come out and i can't charge. anybody know somebody or someplace that i can take the laptop to get it fixed? i live in diamond bar, by pomona but work in monterey park. california by the way. help!!!!!
