[QUOTE="denamtyler, post: 400637, member: 31616"] I have an imac g4 15" flat panel that started to unexpectedly power down when I was listening to music on iTunes. I could turn it back on manually with a bit of persistance and then finally it just wouldn't turn on anymore. I did a bit of research and found out about the PMU reset and tried that. The computer did start up after this reset but then powered down again after about 15 minutes and is dead again. I have no experience disassembling computers but am mechanically inclined. I have obtained the service manual for the computer and according to the research that I have been doing, I am going to follow these steps one by one to try and resolve my problem. 1. replace the ac adaptor/power cord - the original has been quite abused 2. try resetting the PMU with the new power cord 3. Zap the PRAM 3. replace the PRAM battery 4. replace the power supply Does this sound like a logical chain of troubleshooting? Do you have any suggestions where to purchase the supplies/parts that I need? [/QUOTE]
