You want to be environmentally responsible and not just throw old rechargeable batteries in the trash bin. Lenovo has the answers for you. Below are two great programs allowing you to recycle Lenovo machines in an easy responsible way.
Lenovo offers environmentally sound managed asset recovery services (ARS) and product take back and recycling programs to business and consumer customers, respectively, in many countries around the world. These offerings are designed to satisfy specific customer and geographic needs while maximizing the reuse, recycling, and/or environmental disposal of replaced and end of life products, parts, and waste.
Lenovo recommends that prior to returning equipment for recycling, that you back up or transfer any data on the hard drive or other storage devices and then delete any data on the drives and devices. Lenovo recommends consumers use one of the variety of commercially available data-erasing software applications available on the market and follow the instructions associated with the software to ensure data is removed from the machine prior to returning for recycling.
