    My ibook G4 will not start. When I press the power button, the fan starts, but the screen does not turn on. The light comes on on the power cord when I plug it in, but that is all of the activity I can get out the computer. I have had it about 4 years.

Some computer react this way when the logic board goes bad or have a defect in it.  
First, Try this:  
Remove the battery.  Plug back in the power cord, then press and hold down the power button til you hear a loud beep sound. then release it.  If the computer starts back up... Then you should be okay.
If not, it may has something to do with the logic board.
Let me know if the above works... We may can try some other things if not.

you should never shut it off with the power button unless it is not responding. When you turn the computer on, hold down the option key, and select Macintosh Hard Drive when it gives you a picture of a hard drive.

My computer is starting up, but it is slow and without icons. it is g4 ibook mac only background blue i can move my mouse over the screen. thanks


From a powered-down state, press the power key and immediately hold down the shift key (safe boot) until the Mac boots all the way to the desktop. If this fixes the problem, you have some global or local system preference that is interfering with the operation of your machine. If this does not solve the problem, you may have a faulty hard drive. If you head the hard drive making periodic noises when the blue screen is present, it may be the system trying and failing to read a data block that it needs in order to proceed. In this case, your hard drive will need replacement.

IBook G4 will not come on


You should be able to sucessfully boot from the original installation CD. If not, there is another problem with the computer. The iBook G4's are known to have logic board problems, which could very well be causing this problem. The logic board problem is very costly to fix. Over $300. There are solutions that you can do yourself online. I did this on my iBook and it continued working. Let me know and I'll send you a link to repair this yourself.

Computer won't show start up screen, only shows different colors ie. green, then pink, blue... i took out the battery and started it without the battery and got the same results.


First you need to reset the PRAM:
  1. Shut down the computer.
  2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
  3. Turn on the computer.
  4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
  5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
  6. Release the keys.
Next you need to reset the PMU (power management unit). This will depend on the model of your iBook so follow the instructions on Apples page:

Hope this gets you going again

All the best
