Hey Guys!!!! I have searched for a bit on this forum but could not really come up with a problem just like mine. My first mini has a problem. It will power on with the light and then promptly turn off in about 3 seconds. The hard drive spins up but the fan does not turn on. No image on the screen or anything. the mini is open for diagnosis and will do the same thing if the cpu is not installed. Interesting question what will a mini do when it is powered on but doesnt have its cpu installed?
