Working iBook G3 600, running Panther with all updates installed. Had 384 meg RAM. Removed 256K and installed known good 512 from G3 Powerbook. iBook failed to book. Powers on but screen remains black. Restored RAM in PowerBook - works fine. Reinstalled orig. 256M in iBook. Video issue remained. Removed SO-DIMM. iBook boots. Have tried other SO-DIMMs of varying capacity. iBook video will not power on with RAM slot populated. Have tried zapping PRAM when slot is empty. Still no video if RAM is installed. Any suggestions? Causes?
Thanks
