Are you saying that what you observe is the same as unplugging the Mac?
Are you getting a kernel panic when you restart?

Just what model Mac do you have?
You posted in the Mac pro desktop forum. All Mac Pros have Intel processors. Power PC Mavs have Power PC processors.
The 2006-2012 Mac Pros come in silver towers and the G5 Power Macs also came in very similar silver towers
The backs of a Power Mac G5 (left) and a Mac Pro (right) show the differences in arrangement. Note the dual fans on the Power Mac and the single fan on the Mac Pro as well as the new I/O port arrangement.
