My 15" Ti-book, 800MHz, 1 GB RAM, running OS 10.4.2 will not shut
down or restart using menu commands. It goes to the blank blue
screen and stays there. I can get it to shut down by holding down
the start button for a few seconds. It won't restart using any
software or hardware methods. I have to force a shutdown and then do
a cold reboot.
Repair the drive then repair permissions.
Make sure you don't have any broken shutdown items running.
I read Luis' post on getting his Superdrive to work again via the
Terminal by using cmd-opt-o-f and then typing eject cd reset-nvram
reset-all.
Not terminal (the Unix command shell). Holding down opt-cmd-O-F at
restart puts you into the Open Firmware command shell. Open Firmware
is the primary bootstap program, that runs out of your Mac's Boot
ROM. It manages the whole boot process (of whatever operating
systems you have loaded onto the HDs).
Leaving out eject cd command line, would the rest of the commands
possibly clear the problem or is the solution more likely by
removing the keyboard and hitting the reset the pmu button? TIA.
Worth a shot. Certainly less tromatic than opening the hardware. :)
