However, why do you say the system is not dead when you plug in a console..
but there is nothing on the screen and it doesn't respond to
control-alt-delete. To me that sounds like 'dead'. Usually the cpu is
hardlocked or the hardware went into 'over-heat' and put everything in a
deep sleep hoping it would cool down but never wake up.
