Hello all. My second hand Powerbook G4 starts, the bitten apple comes up, then there is no further boot up action. The situation leading to this was as follows;
- firstly, starting but going to a blank/grey screen and staying there. The new variant alluded to, which I have not been able to find referred to, was that at this stage, one could for a while, actually type letters (coming out in white). After a while this stops.
- researching this problem here I followed the advice in the Grey Screen article - http://support.apple.com/kb/TS2570
one on resetting the PMU - http://support.apple.com/kb/HT1431#faq11
and on using Target Disk Mode - http://support.apple.com/kb/HT1661
None of this helped in the slightest with these symptons.
Because I was away on holiday at the time I did not have access to system disks, or actually using Target Disk Mode. On returning I used TDM to successfully connect to the PB, and it became evident that there is a drive problem. I had taken quite a few edited videos with me and it was possible to copy some off, but not others. Data that refused to copy always led to having to restart the machine because the 'copy' mode would refuse to cancel. I also reinstalled the OS, and using another PB used TDM to allow Diskwarrior and Disk Utility to work on the poorly machine. Both were able to do some work, but not complete all their tasks. The SMART, so called, diagnostics always came up fine.
Now if I turn it on the grey screen stage is not reached, the apple symbol comes up and stays there, with no spinning wheels.
So, is there anything else I can do?
Is the grey screen with some typing possible relevant or interesting in any way?
