Introduction

This guide shows how to replace the battery in a Lenovo ThinkPad T14 Gen 1. The battery supplies power to the laptop, and replacement may be necessary if it can no longer hold a charge.

Before you begin, completely power off the computer and disconnect the charging adapter and any external peripherals. Work on a clean, uncluttered surface to reduce the risk of damage or injury while handling internal components.
