Computer will not start up
I logged out of my iMac and turned off my computer so that I could move it. After I moved it, I plugged it in and tried to turn it on. I only have a black screen.
iMac 27″, OS X 10.11
1) Check the power cord on the back of the iMac to make sure that it is firmly seated.
2) Check the wall outlet with another device like a light to see if it has power.
3) Check the trip switch on the surge protector if you are using one.
