Today I replaced the Logic Board (Motherboard for you PC people) on a coworkers powerbook. THis machine has been to hell and back. It was dropped and the ram clips were broken. It would boot up and have no video. The coworker bought a replacement logic board on ebay and I just finished installing it for him. Everything booted up just like it should. I didn’t have any extra screws, so I guess I did it right. 🙂 I used the following guide to help me with the process.
