    I have a g4 ibook and i have been trying to install leopard on it, i have a retail copy of leopard and every time i hold c down or have the installer reboot the laptop it brings up the apple logo with the spinning gear and then the screen goes black, i can hear the DVD drive spinning but that's about it, the drive works and the laptop is updated, I'm upgrading from 10.4.11 tiger

    specs

    1.33 ghz ppc g4

    1.5 gig ram

    40 gig hard drive

    any suggestions would be awesome :D

    I've installed Leopard on almost the same machine via retail dVD. It takes a ginormous amount of time to boot the DVD though. If you boot without the DVD in, then put the DVD in does OSx see the dvd?

    As old-wiz mentioned it does take a considerable amount of time to boot from a DVD, could the display be going to sleep?

    its not going to sleep, it does it right after it finishes through the spinning gear which only takes about a min, its really strange the screen just goes dark, the computer is running tiger right just fine never had hard drive issues or screen problems, i just have to update so i can use iTunes and what not

    ----------

    yea i can access the dvd through tiger, when i put the dvd in it drops a icon on the desktop

    I don't have any idea if this is the same issue that affecting you but I found mentions on the net of the backlight getting turned off (or not getting turned on) during the installation of Snow Leopard. Apparently, if you use a flashlight you can see what's on the display and continue the installation. After the installation is complete it will work normally.

    i don't know why this happened but for some reason the display brightness was turned all the way down, i navigated with the pen light into system preferences and then went into display and cranked it up, it is working just fine now, i want to thank everyone who had ideas, issue resolved
