Lenovo Thinkpad X1 Carbon 4th Gen Fingerprint Press Scanner Replacement

Introduction

The Lenovo Thinkpad’s fingerprint scanner is a physical feature of the laptop located below the keyboard which enables the user to unlock the laptop by scanning a fingerprint rather than typing in a password. Over time the scanner may lose sensitivity or fail to read fingerprints altogether. If the fingerprint scanner no longer allows you to open your device, it may need to be replaced. This guide will explain how to replace the fingerprint scanner on a Lenovo ThinkPad X1 Carbon 4th Gen, model number: 20FB002LUS.

    • Unscrew the nine captive screws on the bottom cover of the laptop using a Phillips #1 screwdriver.

    • The screws do not fully come out of the back cover, so there is no need for screw management.

    • There are a few small clips around the edge that you may need to pry at to free them. An opening pick may be helpful for this process.
