I have a new Mac Mini with a PC keyboard and a monitor with a VGA plug. I had to get some files off the old PC so I took the above hardware off the mac for a couple days. Turns out I hadn't turned off the mac, it was just in sleep mode when I disconnected everything. When reconnected to the Mac, the keyboard and mouse are fine but the monitor gives me the message "Not Connected, Going To Power Save." It is connected through a VGA adapter, the same setup that was working previously, but now simply goes to power save and shuts off. I've done a couple hard shutdowns with no improvement. I do not know enough apple hotkeys (especially on a PC keyboard) to do much of anything meaningful that may get it to recognize the monitor. Advice appreciated. Wanna kill these ads? We can help!
