My Mac will not power up?
Tried different power cords. is there a fuse or breaker? How do you test power supply?

You can check out the power supply by plugging in a USB powered device. If the the device works the power supply should be good. Ralph

Thanks - no power at USB - taking it in for new power supply
+ for the link although you have to press the power button to use this test, that's where my question came in. Thanks for the trouble of looking this up!
