I've recently picked up a 14 inch mid-2005 iBook G4 (1.42 GHz) that has a bit of an unusual problem. I've got a 1 gigabyte RAM stick installed in it, and when I boot up the computer it recognizes it perfectly. However, if I reboot it it goes back to only recognizing the soldered 512 MB on the motherboard. If I shut down the computer and unplug it (the battery is shot), it recognizes the RAM again after I plug it back in and start it up. When it doesn't recognize the RAM, it still boots, but it only uses 512 megabytes. Has anyone seen this problem? Its completely new to me.
This problem persisted after a fresh install of Leopard (upgrading from Tiger).
