Melvetta, I seem to have missed your earlier message. Can you try, or have your tried: (a) Touching the switch on the Cube? (b) Touching the switch on your Apple Studio Screen? (c) Power-up button on the Keyboard (but you might not have one)? (d) with power off, disconnecting and re-connecting everything a few times (with a view to cleaning the connections)? (e) preventing your pets sleeping on the power brick? (f) checking the power supply at the wall socket? Do you get any response at all? Pulsing white LED? "Boing" sound? Hard disk scufflings? Profound silence? Red light seen inside the Cube - visible from underneath? Sorry to ask silly questions, but you might be surprised! Answers to some of these questions could well elicit suggestions from some of the very knowledgeable subscribers to his list. David.
