Introduction
Use this guide to replace the coin cell battery in your Lenovo ThinkPad T460.
A coin cell battery, also called a CMOS battery, is responsible for remembering specific information such as the computer’s date, time, and BIOS settings when the laptop is turned off.
When the coin cell battery fails, an error message will appear when you power on your laptop.
Make sure to [link|https://www.manualslib.com/manual/1171577/Lenovo-Thinkpad-T460.html?page=66|disable the internal battery], power down your device, and disconnect from any external power sources before you begin.
