My Computer Won't Even Turn On

Symptoms
If your Macintosh computer won't turn on, here's how to troubleshoot it. Please keep in mind that although your computer may display similar symptoms that prevent it from showing video, this article discusses what to do if the computer won't turn on, meaning that when you press the power button:
· You don't hear a startup chime
· You don't hear any fan or drive noise
· The power button or power indicator doesn't light up at all
If your computer doesn't display any video, it may display one or more of these similar symptoms when you press the power button:
· You may hear a startup chime
· You may hear fan or drive noise
· You may see the power button or power indicator light up
If any of these conditions occurs, see the Troubleshooting: My computer has no video article instead.

Resolution
If your computer won't turn on, try each of these steps:
1. Make sure that the power cord is plugged into a working wall outlet, and that it's properly connected to the power adapter. (To check if the wall socket is working, plug in a lamp or other electrical device.)
2. Make sure that the power adapter is properly connected to the power port on the back of the computer.
3. Disconnect all accessories that are plugged into the computer, such as a printer, hub, or iPod.
4. Reset the computer's PMU or PRAM.

5. Try plugging a different power cord into the computer (if you have a working one available). If the computer starts up, replace the old power cord. You can get a replacement cord for some models at the Marin Mac Shop, C Street, San Rafael
6. If the computer uses a power adapter, try connecting a different power adapter to the computer (if you have a working one available). If the computer starts up, replace the old power adapter.
