Introduction
A fingerprint reader on your laptop is an additional security feature that works by capturing the pattern of your finger, analyzing the information and comparing it to the prints on file and then unlocking your device if the prints match. If the reader is not working properly or needs to be replaced on your Lenovo ThinkPad T480, this guide will help you replace it.
The fingerprint reader is not something that needs to be replaced often but in the case that it has been damaged, due to a scratch on the surface for example, it may need to be replaced.
Prior to beginning the repair, disable the internal battery, shut down the device, and unplug it from the charger.

Thanks for this detailed guide. I have a question: will you make a guide for T480s? How similar is the process?
Hi @eriknordquist, You're welcome! I'm sorry I didn't create the fingerprint reader replacement guide for the T480s. Unfortunately, I don't have the laptop anymore but I looked at the T480s Hall Sensor guide and it looks like the fingerprint sensor replacement might be a little easier for the T480s than for the T480. The Fingerprint/Smart Card cable is the one next to the hall sensor cable (to the left). It's connected on both ends with ZIF connectors. I think once you disconnect the cable and lift the black plastic shield or tape, the fingerprint reader should be underneath. I'm not sure what the next step is, but I hope that helps you get started.
Thank you, @sarahw, that's encouraging.
