I found a few apple power adapters in my friends garage and he says he doesn't want them anymore. Two of them are the white-brick style 65w power adapters for iBooks/PowerBooks. One of them is the yoyo style.
My question is how I would tell if they work if I don't have an iBook or PowerBook. I plugged them in, but the lights don't turn on, so I'm not sure. If anyone can help, thank you very much!!!
