so you know; I replaced the DC board about two months ago. now it won't charge or turn on without battery. Why I'm asking is I don't want to shell out the money for a new DC board if it's going to be a waste.. i'm also wondering if it's the power adapter, I have one of those crappy generic ones; and had a few issues with it.. Is it possible to check if there is electricity running through the head that goes into the iBook? Also it will power on with the battery, just doesn't charge. i checked all the connections on the dc board and nothing's wrong with it at eye, i know the dc board is the most common probably, but who knows maybe it's not the dc board again ..? Thanks!
