I´m mechatronic engineer and saw so many examples for planed obsolescence, that i really abhor this approach. Technical advancement could be so much more efficient, if products would be designed to last, witch is an easy task and cost worthy.
Self repair is essential for a better society and can provide important resources also for social skills. I love ifixit!
I just did this with a MPB A1226 to replace the old 120GB Hdd with a fresh 480GB SSD - worked like a charm!
Be very carefull and bee patience. It´s very helpfull to have something like the ifixit magnetic project mat to keep the screws in order, otherwise you will have a hard time to put the parts together.
Great guide - i fixed my PB G4 1,67 without any troubles. My DC-in board had a burned through capacitor. Now it´s loading again the battery and recognizes the powerplug.
Thank you!
