Chosen Solution
As the title States, I was looking at the logic boards and wondered is it possible to upgrade the 867MHz logic board to the 1GHz logic board? I noticed on the 1.33GHz board that it said “Works only in the 12” 1.33 GHz Aluminum G4. This part will NOT work as an upgrade for an 867 MHz or 1 GHz 12" Aluminum" However this notice does not appear to be on the page for the 1GHz logic board.
Yes it should work without any modifications.
Hello! Sorry for the delay. The short answer is that it is not financially feasible. Here’s why: The logic board is shaped a bit differently near the ports, so you would need a different frame as well as logic board (the frame is also different around the fan area, RJ-11 area, and mic/power connector area).The DVI port in the 1 GHz (instead of VGA in 867 MHz) means you need a new lower case to accommodate the port size difference.The display on the 867 MHz machine has the speakers mounted on it and the subwoofer on the logic board. The 1 GHz machine has the speakers AND subwoofer on the display, which changed logic board ports and cables on the speakers.There is a change from a reed switch board in the 867 MHz models to a hall effect sensor in the 1 GHz models.The heat sink is shaped differently in the fan area on the 1 GHz models.The RJ-11 board’s screw hole is moved lower on the 1 GHz models.The fan on the 1 GHz uses a smaller connector.The DC-to-DC board has a different model number printed on it. It may be compatible (I haven’t tested it), but it may also damage the machine. In other words, you would need at minimum to replace the logic board, framework, subwoofer, speakers, lower case, reed switch board, heat sink, fan, and RJ-11 board. That gets expensive! Sorry for the bad news! You’re financially better off either saving for a new machine or upgrading the RAM and hard drive for better performance.
Hi guys, Sorry for the hijack but this seems to be the most accurate place to find an answer. I have a working LCD screen and front display bezel on an 12" 867mhz PowerBook and I want to transfer that to a 12" 1Ghz PowerBook (which doesn’t have an LCD at all). Are they interchangeable? Will it work?
