Help! G4 PowerBook "Detect Displays" triggers shut down message
I think I may have damaged my PowerBook by being too lax with a DVI/VGA adaptor when unplugging it from a VGA multimedia projector - I was in a hurry and removed it from the Mac whilst it was halfway through shutting down. (I've gotten away with this before but have since heard it's not a good thing to do, probably even worse if halfway through shut down).
If I choose Detect Displays now, it triggers the "Are you sure you want to shut the computer down?" message.
I also am unable to boot up successfully unless I hold the Option key during the initial black "chime" screen - the PowerBook appears to die with a squeak - both the HDD and SuperDrive lose power. Option-V won't give me a verbose boot unless I flash the PRAM, and then works only once.
(I've reinstalled Tiger 10.8.4, have run Disk Utility and have flashed the PRAM.)
Has anyone else experienced a similar problem?
