Energy Star Model Information - Lenovo ThinkStation D20 Safety And Warranty Manual

A button-shaped lithium battery is installed on the system board of your Lenovo
computer to provide power to the computer clock while the computer is off or
disconnected from the main power source. If you want to replace it with a new
one, contact your place of purchase or ask for a repair service provided by Lenovo.
If you have replaced it by yourself and want to dispose of the disused lithium
battery, insulate it with vinyl tape, contact your place of purchase, and follow their
instructions. If you use a Lenovo computer at home and need to dispose of a
lithium battery, you must comply with local ordinances and regulations.
