| Can't afford the $75 diagnostic fee .... Hi, I have an iBook G3 Clamshell 466MHz and would like to know if there is a definitive way a novice like myself could determine if the iBook has a defective Logicboard or HD? There is no clicking coming from the HD but I can't boot since I tried to install 3rd Party Ram. The system is Panther and believe me I've tried everything possible that I found in my research over the past week to no avail. The Applestore techs told me on the phone, that it is likely the logicboard/HD but I feel I almost know this iBook inside/out and am curious if it's easy to spot these hardware failures. At the moment the iBooks HD has been zeroed out using TDM and my intel Mac.  |

| Reset PRAM, pmu, and try to see if you can get it to boot without that 3rd party RAM installed. Insert disc 1 that came with the computer, boot with alt to get to Apple hardware test, run it looped (ctrl-L to loop) for a few hours at least.

I don't have access to a PPC mac to try installing Panther using TDM/Firewire. Strangely enough what I haven't been able to do is boot into single user mode. That's Shift at startup isn't it ... What I do have to do though is reset the PMU each and every time I want to try something .... otherwise it's a black screen. I've reset that PMU a gazillion times now.

| I think that resetting the PMU more than several times "kills" the PRAM internal battery. Replace it.

| If I'm not mistaken, I believe these iBooks use the main power battery as the PMU battery as well. So if the battery is dead or close to it, then you'll have issues where the iBook will not retain the correct date and time or it just won't startup at all. I got the following link from Low End Mac's clamshell iBook section: http://docs.info.apple.com/article.html?artnum=58445

| Is the computer turning on at all? If so, what screen does it go to?

| Thank you very much eric2006 for your time! The iBook does power on and goes to the flashing folder/? and if I turn it off and power on again it goes to a black screen so I reset PMU to get it to respond again. I know the FireWire Port functions if that helps. I'm quite frustrated with this 'cos I don't have access to a PPC mac. |
