My powerbook G4 froze with flyspin going.. I shut it down but when I restarted it it went to a blue screen with no activity. Clearly it is not starting up OS X. Any ideas what to do?

Boot it into single-user mode holding down Command(Apple) and S buttons when powering up. Then in terminal console, use chkdsk -fy. Use it and use it again until comes back with something like "Volume appears to be OK". Then use command: mount -uw / and then type reboot and try booting normally.

Unable to install new operating system on ibook G4

If you hold down the option key on startup you should get 2 choices 1 to boot the hard drive 2 to boot the cd/dvd. Use your right arrow key to select the cd/dvd on the right then hit enter.

Or you should be able to boot the cd directly by holding down c on startup.

Hi ihave apple power book g4 i want reboot

login in single user mode as below:

Starting up in single-user or verbose mode
    1. Shut down the computer if it is on.
    2. Press the power button to start the computer.
    3. Immediately press and hold the Command (Apple) key and one of the following:
    • the "s" key for single-user mode. (Command-S)
    • the "v" key for verbose mode. (Command-V)
You have successfully entered single-user or verbose mode when you see white text appear on the screen.

Once you are in the Single user mode type the following:

fsck -fy <then press enter>

If this command returns with an error or reports that is found an error but fixed it then run the command again and repeat until the drive checks good.

Once you are done with the repair or feel satisfied, type 'reboot' and press enter.

My husbands G4 notebook won't boot up, he doesn't have the start up disc. When he turns it on he gets the apple logo and then the screen turns kinda white like it's lit but not bright. Anyway everything I...

The Command key is commonly known as the apple key or it has a four bladed propellor on it or an apple logo (it may also have cmd on it) the option key generally is the one that says "alt" on it

I would say that if this does not work I would suggest going along to your local apple store who will be only willing to help you and give you advice.

Hope this helps

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 powerbook G4 does not chime!!

I suggest you plug it into AC power, then boot with Command-P-R held down until you hear the unit chime twice, then release it. Hopefully, it will boot after this.
If not, boot with Command-O-F held down; when you reach the command line, type
reset-nvram [return-key]
reset-all [return-key]
If it doesn't boot after that, you have deeper issues if the machine is actually turning itself on and off.

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. :-(

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

Always freeze

Firefox will use a lot of disk space over time for temporary use. You might try starting up and run the Disk Utilities program to repair disk permissions.
