Introduction

This guide will show you how to replace the battery of your Lenovo ThinkPad T480s.

A healthy laptop battery will keep your laptop powered on, even when your device is unplugged from an external power source.

If your laptop no longer holds a charge, or loses its charge very quickly, you most likely have a dead or failing battery which may require replacement. Depending on the cause of your faulty battery, you may be able to resolve the issue using this list of troubleshooting symptoms and solutions from Lenovo’s support forum.

Make sure to disable the internal battery, power down your device, and disconnect from any external power sources before you begin.
