Eco Button is a new add-on computer power saving device that has been developed to help the environment and help you as a business. The Eco Button can help you save costs on your electricity bills and save wasted CO2. When the Eco Button is pressed your computer enters energy saving 'ecomode' (the most efficient, lowest power mode available, which actually draws only the same nominal power as when the computer and monitor are turned off!) When you need to use the computer again, simply press any key to instantly return to where you left off. Easy!
