If your Lenovo ThinkPad X1 Carbon 4th Gen (20FB002LUS) is not holding a charge or not charging at all, the battery may need to be replaced. Follow this guide to replace the main lithium-ion battery in your laptop.
The main lithium-ion battery in your laptop is responsible for powering your device when it is not plugged in. Over time, the battery may degrade and drain faster during use—this problem can be solved by replacing the battery.
This guide covers how to replace the primary battery on your laptop. If your device is not powering on at all, it’s recommended that you check the smaller coin cell battery first, since replacing the small coin cell is done more easily and costs less than the larger lithium-ion battery. A guide for replacing the coin cell battery can be found here.
Before starting this guide, make sure to power down the device fully and unplug any exterior sources of power from the laptop.
