Insert the system CD, restart the computer holding down the C key until it boots using the CD. Then run through the initial screens as though you are going to reload the system software until you are given a menu bar. Select Disk Utility from the menu bar when you can and then you can run disk first aid and 'Repair disk'. If this works OK then you are back up and running after a restart. Otherwise you will have to reload the system. Note: when you have booted of the CD, you should be able to access the hard disk and retrieve any files you want first to an external disk or memory stick before reinstalling the system software. Good luck - TT

Reset button on a powerbook g4


The Powerbook G4 power button functions like a reset button if you hold the power button in for a few seconds until the computer powers down.
  1. Hold the power button in for a few seconds (until you see the screen turn off/go black and hear the fans & hard drive stop spinning).
  2. Press the power button again to turn your computer on.
  3. If you have more trouble, you may need to boot in Safe Mode or "perform a Safe Boot":
    Press and hold down the "Shift" key immediately after you hear the start-up tone. Release the "Shift" key when the gray Apple icon appears on the screen.

During boot-up, Apple logo heavily pixelated. After boot-up, display a riot of colors and vertical lines with nothing readable. External monitor works well

I'll appreciate any input.

When i try to boot my ibook g4 it gets stuck on a blue screen or the mac logo and it brings up a sign saying to shut down or restart.. i do this but it does it all over again..


The sign i believe you are referring to is a Kernel Panic, if it is a gray box that dims the screen. Example: http://www.ourhangout.net/archives/Kernel_Panic-1p0f.png
If this is the case, and you have your Mac OS X install dvd, try to boot off of the disc and use disk utility to repair the hard drive.

HELP!!! I am trying to start my Powerbook G4 but as soon as it turns on I just get a grey screen that says that i need to restart my computer. i tried restarting it like 10 times. what else can i do?


Also, check your RAM bay port to see if one of the RAM boards came dislodged and is not inserted correctly. Could also be one of your RAM boards is not compatible or one of the RAM boards is defective.

Powerbook Aluminum G4 15 booting up problem


The backup battery connects directly to the logic board. From the symptoms you are describing (rather clearly, thank you), it seems apparent that your logic board may be faulty.
There are two more things you can try.
1) Reset Open Firmware: Unplug-replug your backup battery, then boot the system holding down Control-Option-O-F. Your machine will boot into Open Firmware. Type the following commands, pressing the "return" key at the end of each one:
reset-nvram
set-defaults
reset all
Your machine should restart at this point. If it starts successfully, you should be done. Otherwise,
2) Reset the Power Manager. Turn the machine all the way off (no power). Simultaneously press Shift-Control-Option-power button, then release. (Do not press the fn (Function) key during this sequence.) Wait five seconds, then press the power button. If it starts successfully, you should be done. Otherwise, you will need to see a man about a logic board, which is probably not a cost-effective repair on a 1GHz G4.

Kernal panic alert screen will not respond


Well, if you erase the wrong files, you'll sure get a kernel panic.
To power down your PowerBook when there is a kernel panic on the screen (or any frozen state) you have to hold the power button for 10-15 seconds until the Mac shuts off. Then you can restart it.
If you deleted too many of the wrong files, it may not restart to your satisfaction. :-(

Apple mac g4 laptop wont come on


Kernel panics are not what you have, you have a flashing question mark, it indicates there is a problem with either the hard drive or the operating system on the hard drive.

Kernel panics are different, the unit tries to start and then the unit crashes with a "kernel panic"
