My Mac Pro will not power on …
Friday, June 4, 2010 / Mac Pro, Power Supply, Troubleshooting
Jacob,
My brand new Nehalem, which has been running fine since I got it, will not power on – no response to the power button. I tried the SMC reset twice but no luck … Is there anything else I can do?

With the unit off, try holding in the power button for a long time until you hear Tone from the speakers. Release the power button and after a short time it should chime and boot. If that fails, than your Mac Pro could have a power problem. For diagnostic sake move it to a new outlet and directly connect the computer to the wall, bypassing any power strips. If it still will not work, then it will need to be looked at by an Apple Authorized service center.
Hope this helps, let me know,
- Jacob
