Is my power supply failing?
I have a Mac Pro 3,1 2008. The machine start up automatically when I connect the power cable to the socket. I did not even press the power button.
Also, when I shut down the machine, the light on top of the power button is still on indicating the machine is still operating but in fact it is shut down.
What is wrong with the machine? Is this the signs of power supply failing or other problems?
Is this a good question?
