I don’t think anyone has reported a faulty battery connection problem. I cracked mine open my battery and connections are fine. My iPad is pristine not a smudge or speck of dust. I will reball the processor this week so I can return the new one I had to buy yesterday. Or failing that , I’ll package my screen and parts and get most of my money back on the secondary market. I test and guarantee everything I sell but it’s still a drag.

I have been researching this and it seems there are 2 programming edits that allow a 32bit version of lion to load and run on core duo machines in developer mode....It is reported that an external Hard Drive pre-loaded with 7.5 and chosen as the startup disk will run in verbose mode or on a virtual PC drive like parallel desktops.There are instructions on several links you can google. I have yet to attempt this on my identical MBP as some users reported earlier OS updates froze some built in applications. It would be nice to sync my other machines and iphone through icloud but I'm waiting for a more stabile edit. That's all I found to date. Have fun fixing and finding more value in your electronics.

Actually, there are 2 different styles of logic boards common to this model 1181. One would use an 820-1889A replacement board ( 2.0, 2.1, 2.4 ) off the top of my head.... The other 2006-early 2007 would use an 820-2279 board which utilizes an Intel T8100 chip set.... Don't be put off by the tech talk. The only real difference is that the speakers fans and sensors have different style connectors but this is extremely important. If you are not sure, you will need to remove the keyboard and and right side RAM chip to see the board number. Be sure to order the proper speed or greater in that board style as some sellers do not specify the processor speed unless asked. The secondary market is alive and well for these replacement boards .... Make sure any part you buy is fully tested and guaranteed.... Good luck... PS I like to use sticky notes on an ice cube tray for screws or step numbers.... Happy fixing
