ibook G4 usb problem

My ibook G4 A1133 usb not getting any power. Since it not getting power it will freeze up on boot up. What will cause the usb not getting power? I went into open firmware and reset everything. Still won't boot up all the way after doing that. When you first turn it on you get the happy chime and you get the apple on screen with the dotted circle moving under the apple then the circle stops and it freezes up. Hope someone ran into this. Thanks for the help.

Well found out if I hookup the internal cd rom the computer freeze on boot. So there got to be a problem with a chipset. Well I got my eye on the same one I got and everything works. Just the screen got a line in it. I can just put my screen on it.

Gernerally USB gets kicked outif a USB item draws too many mA.

Have you done a PRAM reset, ...

Reset NVRAM on your Mac - Apple Support

In fact, do 3 in a row, takes a bit of time.

School may have done something.

Read up on Target Disk Mode, that is where you either...

Boot this one holding T key & you see a big floasting FW symbol, then connect to another FW Mac, then this one wull look like a Gard Drive to the other one.

O, coot the other FW Mac holding T key, connect via FW, then boot this Mac holdiing Option key & see if the other Mac's HDD shows as a bot choice.

I did a reset all on it. I reset the pram and the nvram too. I reset it like 4 or 5 times now. Still now doing nothing. It will start to boot up the freeze up. If I try to boot from a usb stick I get a screen with a circle with a slash on it. But the usb stick boots up on my other power Mac. So I don’t know.

I can’t reinstall the os. The cd rom doesn’t work. The usb won’t work. The FireWire works but doesn’t have anything to plug into it. From terminal I did the command to make it run setup again and made an account for me. Well thanks for the help. I may just buy other one off eBay .

It wouldn’t let me upgrade to Mac OS 10.5. It told me I needed to install it from a dvd. Because it needed to format the hard drive. So I am suck with 10.4.11 for now. I was told I can plug my iBook into an other Mac with FireWire and use the other Mac as a target drive or I could install it over the network. Beats me how to do that. Well thanks for the help.
