You have a firmware problem and it needs to be reset.
try this first: If the computer is on, turn it off. Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-Power on the keyboard. Do not press the fn (Function) key while using this combination of keystrokes.
Wait 5 seconds.
Press the Power button to restart the iBook computer.

If that doesn't work, try this: Turn the laptop off. Remove the battery but leave the mains power attached. Hold the start button down until you hear a loud beeeeep! then release. Wait for the system to reboot and hopefully thats you sorted.

You're following instructions for an IBM-style machine and mouse. You need to be reading instructions for Apple. Often their version of a 'right-click' is to double-click, but it depends on the program. Read your manual about using your mouse, and always look for Apple-specific instructions for any program or application you are using.

How to reset my apple mac i5 2.7GHz 4GB


Resetting the Firmware on an Apple Intel Based Macbook Pro/Mac Mini/Imac/xServ

As soon as you press the power button hold down all the following keys on the keyboard;
CMD, Option, P, R

This will result in the startup chime sounding twice instead of once.

[CMD is the key left of the spacebar, Option is the key left of CMD]

This should fix most POST/Display/Firmware faults if no serious hardware fault is present

Hope this helps! :)

On startup, my power book pro 17" will not open


Hold down Cmd-S as you start it up. You'll get 'single user mode', which is text only. See if there are any obviously bad error messages.
At some point you will hopefully get to a command prompt. You'll see a message telling you which commands to type to mount the filesystem and check for errors - follow that.

You could also type the following to look at the last 50 lines of the log file - perhaps there's a clue to the error in there: tail -50 /var/log/system.log
Restart with shutdown -r now
This may not fix your problem but it might tell you where the problem lies.
Otherwise you can boot from your installation disc and restore from that. You'll then need to get all your documents etc. from your backup.

The prompt for shutdown comes up repeatedly


try starting up with the system/install disk, select language then at the top there is utilities, select disc utility and repair first then repair permissions. Then select startup disc and restart. If this fails then do an archive and install.
