View Full Version : Motherboard compatibility between 1.5 and 1.67Ghz PowerBooks?

Mar 30, 2009, 11:15 PM
Hello community,

I have a beautiful G4 PowerBook, 1.5Ghz with a bad motherboard. I am hoping to replace the mobo with a 1.67Ghz that I am sure works, from a VERY similar model. Would this be possible, or am I out of luck?

Bad motherboard-
1.5 Ghz
Model: PowerBook 5,6

Good motherboard-
1.67 Mhz
Model: PowerBook 5,6

Follow up question- I know it is possible to test the power trickle in the motherboards of G3's to determine whether or not they are working. Is there a similar test to run on these motherboards? Thanks.
