Will not power on
My iMac is connected to an UPS and I had shut it down last friday before leaving on a business trip. Once back home, I tried to power it on and it simply wont :(
When I hook the power cord to the socket(both UPS and direct), I hear a buzzing sound from inside the iMac.
Once I press the power button, I hear the startup sound and then it powers off. Subsequent power button presses does nothing and also I dont hear the buzzing sound until I physically remove the plug from the socket and reconnect it.
I removed my 3-party purchased RAM and is still the same.
Please help solve the problem :(.
