Is it possible to replace MacBook logic board with a later version?
My macbook has developed a problem charging, to the extent that it will only run when connected to the mains, and does not charge the battery at all.
This problem developed slowly over time.
I have had the problem diagnosed professionally and tried replacement of battery, magsafe etc etc but these are not the problem.
After carrying out tests, the technician determined that the problem was with a chip on the logic board that controls what the computer does with power; i.e. directing it to the battery etc.
He said that the only way to fix this was to replace the logic board, but that the macbook would continue to work fine connected to mains, which has proved to be true for a number of months.
I am reluctant to spend so much money on repairing a macbook that is now quite old and may need replacement soon anyway. At the same time the macbook is absolutely fine for my uses and I do not need an upgrade yet and as such am reluctant to spend the money until I really need an upgrade.
So, is there a cheaper way to fix this? And if I do replace the logic board can i at least replace it with a later model and get more value for money / a few more years out of my macbook before upgrading?
2.0GHz (Intel core duo)
The specs to your MacBook are here. With the bottom case and the backlight inverter cable you have the best you can go up to is the 2.16 GHz Core 2 Duo. That doesn't buy you much by looking at the numbers. However that processor/board has twice the processor cache 2 MB vs 4 MB which means it can store more repeated subroutines from programs, making it faster on many operations. That board also supports more RAM, memory, than your current board. The 2.16 is also 64 bit architecture and yours is 32 bit. There are enough subtle differences that you would realize better performance. The specs for the 2.16 are here.
Another option you have is to buy the bottom case from the 2008 black MacBook, along with the heatsink and inverter cable to fit that era of MacBook and you can go up to the 2.4 GHz board.
Here is a video explaining the things you need to pay attention to when changing motherboards for the A1181, pre Unibody, MacBooks.
I hope I have helped you more than confused you.
