Do computers and monitors use more energy with power management activated due to power surges when cycling on and off?
Many believe that leaving lights, computers, and other appliances on uses less energy than turning them off and also makes them last longer. On the contrary, the small surge of power created when some devices are turned on is vastly smaller than the energy used by running the device when it is not needed. While it used to be the case that cycling appliances and lighting on and off drastically reduced their useful lifetimes, these problems have been largely overcome through better design.
