On the PowerBook G4 Titanium Mercury (400 MHz),
I did the procedure in your video for disconnecting and then reconnecting the PRAM Battery connection, which worked and so I was able to start up successfully (thank you), and then shut down and restart it again several times, however, after a few days, I was not able to restart it again with the PRAM Battery connected.
So, I disconnected the PRAM Battery again, and was able to successfully restart it again, but this time I am going to leave the PRAM Battery disconnected and wait a few days to see if it will restart again with the PRAM Battery staying disconnected...
Do you know of any problems that may be caused by leaving the PRAM Battery disconnected permanently?
Thank you for all your help,
