My friend is totally married to her iBook G3; it is and contains her life. She basically uses it for myspace and blogging and iTunes, so she doesn't need anything new necessarily. The problem is, the end of her charger broke off inside of the power supply port on the iBook. Now, nothing happens when you try to start the iBook. I can insert the broken power adapter into the port and get a green light. After two and a half hours to wait for a Mac "Genius", he told me that I wasn't necessarily getting a charge and that it could only be getting enough power just for that light. He quoted me on a new adapter at $79 and new power supply at $200. I'm afraid if I have her spend the money, she'll get it fixed only to end up having a fried logic board or something. Is there any way to replace the power supply cheaper? Can I do it myself? Should I just have her get a new computer? Are HDD's easy to salvage from these iBooks?
