Wilfred, I wish I could help you more. My first impression is that your hard drive isn't being recognized at all. It appears that you are only going so far in your installation via your booted disc and your RAM. When it actually comes to installing your OS onto your hard drive it stops because your Ram can only handle so much data. I hope I am being clear. I would troubleshoot that aspect first. When you say, "Now, I can't get it to power up at all." Do you mean that there is no electricity at all in your iBook? If that is the case that "might" be a problem with your "Power Block" and not your iBook per se. That could explain why your battery isn't retaining power and is being depleted. Find access to another power block and see if your iBook starts up. Take it all back to where you got the machine and test it using their equipment. Good luck, Bill
