Disposing of disused lithium batteries from Lenovo
computers
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.
