Powerbook G4 15" A1046 1.25 GHz CPU Motherboard (Logic Board) 820-1441-A

 

As you can see from the pictures this works just fine, including the two RAM slots.

RAM is included with this listing. While you may want to upgrade, it would be good to use these for a few weeks to be sure everything is working for you.


This was taken from a working 1.25GHz, and it passed the System Check, and also my extensive testing (as seen in the pictures). 
Including the functioning of the 64MB VRAM, the 512MB L2 cache, 
both RAM chip slots.

Apple Part #  820-1441-A

This will also work in a 1.0GHz Powerbook.

There are many helpful web sites to help in the installation of this. However, note this may not be easy for the average person, and of course I can't take responsibility if something goes wrong in installation. For helpful information Google search

You may find that unscrewing and gently lifting the right display hinge out a few millimeters (as shown in the last picture) makes installation easier.
