    Hi!

    this time I've picked up a 14' ibook G4 (1.2 GHz version) for 25€, the graphics card is messed up and would need reballing... I would like to know it there are any other logic boards that fit this model and are a direct swap, if I could find a cheap one I would go that way instead of trying to repair the original board...

    thanks in advance!

    1-Logic Board cost more than buying another iBook G4.
    2-It's really complicated to get into iBooks! You can't really get further than the AirPort card (if the G4 have one) and the RAM slot. It's enough complicated to get into the hard drive, so I don't imagine how much work you need to swap logic board

    I think finding another iBook G4 would be waaaaaay easier than replacing the logic board. Unless you really want to have the same iBook G4 and repair it, Google it! But trust me, I have an iMac G4 that I brought for 90$, the logic board costs 300$.

    Logic boards for iBook G4s are like $30 on eBay. I saw 1.42GHz, the fastest speed available for those for $50. So definitely not over the cost of buying another iBook.

    OP I personally would go with another 1.2GHz board just to be safe on fitment. There aren't any faster iBooks than 1.42GHz, so .2GHz isn't a big difference if you wanna save some cash and be safe on fitment.

    thanks for the feedback... in search of a compatible logic board, I became somewhat confused... do the 12 inch and 14 inch iBooks share the same logic board? because the reference number 820-1646-A is the same...

    Of course, the 14 inch is bigger, the ports are all on the left, why you don't watch a ibook 14 inch disassembly video? Maybe this would help. Or search an image that compare both logic boards.;)

    From my recollection, the guts of those two iBooks are different, making the logic boards incompatible.

    you can use any 14" board from the following; 933ghz, 1.0ghz, 1.07ghz, 1.2ghz, or 1.33ghz as a direct swap. i would stay away from the 933 and 1.0 boards as they were more prone to fail. going slower wouldn't be a good use of time/money, so i'd look for a 1.2 or 1.33 board. the 1.42 board won't fit as they changed the frame/mounts on the final model.

    the difference between the 12" and 14" was the heat sink assembly and the battery connector. on the 12" board, the battery connector is a header mounted directly on the logic board, on the 14" it is a plug and has a short cable/header that mounts on the frame. they are NOT inter-changeable. if you are watching auctions with pictures, that's an easy way to tell them apart.

    nice try, but completely wrong. same EXACT size, the 12" board will actually mount in the 14" frame as the board size/holes are identical, but as above the battery connector and heatsink assemblies are different. both boards have all the connectors on the left, and always have. exactly the same connectors in exactly the same spots. i don't need to search images, i have several of both sizes here in my office to compare. you might want to post on topics you actually know about, it might be more helpful. ;)

    Thanks for the guidelines, that's what I was hoping someone could tell me... I will therefore search for a 1.33 GHz board, so I can both recover and upgrade
    the iBook!
