I had the error 29 for days and tried all sort of things, in the end I decided to try changing the battery as described by many forums, I bought a proper Apple battery APN 616 0435 and one of these from ebay ichanged it to the apple one first and still got error 29!! GRRR so i thought what the heck I might as well try the gold business battery....guess what! it worked and is working perfectly now!

hope this helps Wombatt
