If you get no activity when pushing the power switch button then you top case might be in trouble. Try to power your iBook directly from the logic board. To do it, disconnect the AC adapter, remove the battery, remove the top case, carefully disconnect the power switch connector (blue & white cables) from the socket then plug the ac adapter and briefly short the two small pins inside the power switch socket with a small jeweler flat screwdriver. That should power on the logic board and the iBook should boot the system. BTW, it's normal that the logic board is getting hot when charging the battery. Do you use the 65 watts AC adapter ?
