My motherboard went out on me on my G3 iBook. The shop quoted me at $400 plus to fix. Is this true? Can I fix it myself or at least buy a motherboard and have them fix it. They are saying its $300+ for the board and $100 for the labor. Any ideas?
Look for a replacement logic board on eBay or somewhere like iFixIt. You are really going to be better in the long run putting that towards 50% (or more) of a new MacBook though...
The components and labor do truly cost that much. I strongly suggest that you don't try to replace the logicboard yourself either unless you're extremely comfortable working with small electronics. Even I won't touch the internals of an iBook.
Well, you'll either need a working computer or pull the harddrive and attach it to another machine. Of course you should have backups, replying on the disk not dying is a really bad plan.
