This is a very basic electronics question, so I hope this is an appropriate forum. When an electronic device is plugged into a power strip, does it make any difference to the device whether it is unplugged and re-plugged from the power strip or if the power strip is switched on or off. I have someone telling me that the life of a piece of electronic equipment is being shortened by switching the power strip on and off. They insist that I should only unplug and re-plug the power adapter of this piece of equipment. Is there a real difference with a relatively new power strip?
