Re: PowerBook G4 15

REplacing the keyboard on this model requires removing the top case, disconnecting the ribbon cable from the logic board and extracting the keyboard from the top case. Make sure you remove the battery from the computer first. You will need a jeweler's phillips and a torx 6 for the top left and right torx. It will require for you to peel back the mylar and backlight cabling ( if your Aluminum has a backlight keyboard )

Before doing this thought, i would try resetting the PRAM and NVRAM.

Keep me posted if you have more questions on this.

Apple Powerbook G4 keyboard does not work

The problem is the ribbon connectors is loose connector on the motherboard. The fix is to remove the keyboard, disconnect the ribbon connector from the socket on the motherboard and insert a very slim piece of plastic in that connector to hold the ribbon connector tighter in the connector in the motherboard, once that's done replace to keyboard. The keyboard should work.

Typing numbers instead of letters

Sounds like you may just have your numlock on. Just press function key plus F6 (on a macboook) and the numlock is off. If not you may have a broken keyboard. You can try to replace the keyboard yourself using an Apple Tablet Repair Guide or send it to a third party service Apple Tablet Repair.

Some keys won't work; delete, tab, spacebar, pg down, pg left (but pg up and right work) my external keyboard works fine. Help?

most of the time the problem is caused by a bad or worn out membrane. This is a green looking bar that is under the keys. You can find a replacement on ebay. Whomever you buy the membrane for will be able to give you detailed instructions on how to replace it. On a toshiba laptop, it takes 5 screws to replace. If you look at the bottom of your laptop, you will see a keyboard icon and that tells you which screws need to be taken out.

My mac powerbook g4 12'' wont chime or boot just comes on and screen changes colors every 2 seconds

Resetting PRAM and NVRAM
  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.
Your computer's PRAM and the NVRAM are reset to the default values. The clock settings may be reset to a default date on some models.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Keyboard either freezes up or nonsenseical screens pop up

Sorry to hear you are having trouble,
Well, unfortunately, this PowerBook has the trackpad and the keyboard on the same cable connected to the motherboard. ( When you say the mouse works, you actually meant the trackpad right ? )
Cleaning does not help, we had the same problem but in reverse, the keyboard worked fine but the trackpad would not, even the click...
Apple will replace the entire top case to repair this even though it's just a little cable, that cable is really hard to replace by itself.
Sorry, it's a 200$ repair job.

When typing it writes number 9 all the time

How often? Can you make it happen on demand?
Acquire any other USB keyboard, and plug it into a USB port on your PowerBook. Use this keyboard for a while. If you don't see the problem, then I suspect some sort of short in your keyboard cable, or perhaps a spill in the keyboard itself.
PowerBook G4 keyboards are very easily replaced, without opening up the laptop itself.
