Question about Apple PowerBook G4 Mac Notebook

2 Answers

Screen moves in reverse direction to curso

When using the trackpad on my G4 laptop, the screen moves about half a centimetre in the opposite direction to the cursor on initial trackpad input, and during any subsequent change in direction. Is this problem likely to be software or hardware related? This problem developed spontaneously about a month ago. I have recently updated to Leopard, same problem. I installed two-finge trackpad scrolling around a year ago, no problems, but wonder if it might be related to this?

    I managed to fix the problem by using the Apple-F12 function key combination, which I found at this site. But thanks

Go to the system preferences and look at the universal access, check to see if you have turned on the "seeing" section, if so turn it off, this might be the source of the problem

Screne jumps up and down

Are you talking about the image on the screen moving around, it could be that you have zoomed the image by hitting the ctrl key and pushing up on the trackpad. Try holding down the ctrl key and pull your finger back on the trackpad.

My ibook g4 track pad works when i move it around the screen but i cannot click a link without having to use the button. how do i fix this.

More than likely, you have the preference for "tap to click" turned off. To fix this:
  1. Go to Applications/ or the System Preferences dock icon
  2. Click on the Mouse preference button
  3. Make sure that the checkbox next to "Tap to click" is turned ticked
* If you are using a more recent version of OS X you will instead see a "trackpad" option in System preferences. This is what you want to select to change this setting

Curser stuck in upper left hand corner

If you want to use a mouse with your laptop, find the preference that ignores the trackpad when the mouse is present. Go to System Preferences in the Apple menu (upper left corner of screen). Click Keyboard and Mouse" or Trackpad (depending on what you see). Un-check the option that says something like "Ignore the trackpad when the mouse is present."

(I don't see it in anymore 10.6, which won't run on your PowerBook anyway.)

Good luck!

Typing moves?

It could be that your hands are brushing against your trackpad.

Apple iBook G4 Track Pad (Mouse) not funtioning

I think the first thing you should do is make all updates. I know that in some versions of the iBook G4, the trackpad does not work after installing OS X 10.4 (Tiger) before you do the updates. Update your OS X first. secondly, does the button work? Does the trackpad show up in the System Preferences menu? (under keyboard and mouse). It's very unlikely that the trackpad came unhooked unless someone has opened up your computer. If they have, there is a really good chance that they didn't plug it back in, because it's a hassle and easy to forget.

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.

Failure to reboot after a Software update.

Hi stuart,
It sounds like you either may have a corrupt system or a faulty hard drive. Try reinstalling OSX with the system discs that came with the computer. You can still keep everything if choose the "Archive and install" option.
If this doesn't help, then I'd say the hard drive may have seen its last days.

Trouble with screen (powerbook G4 15" 1.67 GHz)

Well the issue isn't with the graphic card. It actually is the screen of the PB (PowerBook). I had somewhat of the same issue about 6 months ago on my 17" PB G4. But when it started to do that with mine, the screen would also make sharp vertical lines when opening and/or adjusting angle. So before my Apple Care warranty expired I had the screen fixed FREE. So, if you do have your Apple Care warranty still and not expired, I'd suggest to you to find a Apple Certified computer shop or the nearest Apple store and drop it off with the explanation to have the screen replaced. Otherwise you will have to pay a pretty penny.

And if you do not have the warranty then i suggest you not to take it to a Apple store due to the extreme cost of a new screen on an old machine. Instead goto This site is great for anyone who has anything portable from Apple (including the non-portable MAC-mini) for replacement or upgrade parts, cheaper and also helps with the install (DIY instructions and pictures to go with it)

Powerbook G4 (1 GHz), 15" LCD glitchy

It could well be the ribbon cable between the screen and motherboard is knackered. Depends how brave you are at dismanteling computers, if you search on powerbook parts you may be able to find a company that scraps computers who could sell you the cable if it is a separate item otherwise it will be an expensive Apple repair!
