What is my Logic board reference number?
Following damage to my macbook (13-inch late 2009)
2.26GHz Intel Core 2 Duo
8GB 1067MHz DDR3
NVIDIA GeForce 9400M 256 MB
Serial number: W90054828PW
I have decided to replace the logic board with a 2nd hand one. However, there seem to be two reference numbers for the same model computer:
1) 820-2567-A 661-5395
2) 820-2883-A P7550
Will they both be compatible with my computer?
Is there likely to be much difference?
How do I find the reference number of my original?
Any comments gratefully received. Thanks.
