I can't say i can give you the schematic diagram of the logic board but i can tell you that since the board isn't one solid board like PC's and instead is multiple boards connected by flat ribbon cables you might be able to just replace that section of the iBook. So with that said, if you go to you can find most of Apple's portables solutions and parts there. They can also provide you with the exact step by step instructions on how to replace or install new/refurbished parts.

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.

When I power the laptop on I am just getting a ? in the centre of the Screen. Any idea what the problem may be?

That's what the Mac does when it doesn't find the startup folder and can't load OS X. There are several possible causes. The hard drive may have worked loose from its connector, which sometimes happens because of all the handling a laptop gets. The drive or startup folder may have gotten corrupted so that the data isn't readable. The drive may have picked now to go bad so that it's not being detected, or there might be a motherboard problem so that it's not reading the drive.

If you have a Mac OS X install disc, you can try the hard drive utility and see if the drive is being detected. You can also try repairing the disk from the First Aid tab of the disk utility.

Problem with charging the battery, the contact in the notebook does not seem to work all the times, like a false contact and does not charge the battery

This is a really common problem, which can only be two things: the connector on the power adapter wire or the connector inside the laptop. If you're lucky it's the wire and you only have to buy a new power adapter. If it's in the laptop then often it's actually a part of the motherboard, which is expensive and very hard to replace. You should take the laptop to your local Apple store for verification. Good luck!

G4 ibook works off charger, but not battery. battery at 75%

Replace your battery.
When a battery is dead, the charge level it reports is meaningless. When a battery reports a charge but still won't keep your machine running for more than 30 seconds, it's dead.
The fact that the OS knows when the battery is present or absent doesn't mean anything, as it it just reading the presence of the battery interface board.

Re: Video Card TOAST???

Given the environment and issue, sometimes a solid way to process of eliminate, is to add a display to the laptop. Laptop videocards are embedded/integrated in the motherboard/logic board. So, your Mac has not been specified. This provides for many variables. I'll keep this simple but thorough.

First, monitors. Unless you have a great hook up from the next level, you will most likely have a:
  • VGA monitor. if the monitor has the cable attached to it, and not via connectors, but actually runs into the back of the monitor, odds are it's VGA.
  • DVI monitor. Most DVI monitors do have atleast a VGA input.
DVI is digital and far more robust, but the cables and connectors might not outweight what you gain from it if you're not using it to, watch movies, edit video and or edit high resolution photo. If you already own a DVI monitor, then I feel the cable ( if 3-6 ft) and the "possible adapter"
($20) is well worth enjoying what you've paid for.

The "possible adapter" is a white (made by Apple for Apple) proprietary adapter that is required to connect any Macintosh laptop that IS NOT of the ALUMINUM POWERBOOK or MAC BOOK or MACBOOK PRO series, to a monitor. All recent Macintosh laptops ship with 1 form or another of a video adapter.

  • Mini VGA to VGA
  • Mini DVI to DVI
If you need to cross over VGA to DVI and DVI to VGA adapters are available, but you will then have to make note of the gender of the connecting port or cable end.

So, if you own:
  • A white G3/G4 IBook, the video output connection is MINI VGA.
  • Older Titanium Powerbooks, pre 667Mhz have a standard VGA on the rear.
  • 667Mhz-1Ghz Titanium Powerbook, all Aluminum Powerbooks, and ALL Macbook Pros have an on-board DVI female ports. In the rear for TIbooks and Rear right side on Aluminumbooks and MBPs.
  • All Macbooks utilize mini DVI.

Connect a display to your laptop. If you get a picture, than more than likely, any component from the cable that runs from the motherboard, up into the display panel, to the inside of the display, is faulty.

If you do not get a picture, than its highly possible the video card or GPU has failed.

If you could specify your model, I can further assist you.
