PB G4 Boots Then Provides Shut Down Message
I have the following computed purchased in June 2004:
12 Inch Powerbook G4 1GHZ/256/40/SD/BT
Original Software and Restore Discs
Part Number- M9008LL/A
Serial Number- UV ******PHL
This vintage PB boots-up and then shuts down with this message- "You need to restart your computer. Hold down the Power button for several seconds or press the restart button."
I have held down the Power button and the computer accomplishes a hard shut down. Restarts result in similar message/result.
The powerbook OS has been upgraded to the highest version the Motorola PPC chip type will accept which is a version of Lion, but I do not have a a OS software or restore disc for that upgrade. I have the computer backed-up via Time Machine.
What are my options? Thanks in advance for your help.
