Introduction

This guide shows you how to replace the I/O board on your Lenovo Legion Y520-15IKBN. If your Lenovo Legion Y520-15IKBN is experiencing issues with its I/O Board, such as malfunctioning USB ports or audio jacks, this guide will walk you through the process of replacing the I/O Board. The I/O Board, also known as the Input/Output Board, is a crucial component responsible for managing various external connections on your laptop, ensuring seamless interaction with peripherals such as USB drives, headphones, and external displays. If you're encountering problems with these ports, replacing the I/O Board can often resolve these issues and restore full functionality to your device.

Before you begin this repair, turn off your laptop and unplug it from the charging adapter. It is also a idea to remove or disconnect the battery from the motherboard to reduce the chance of damage to your device. Additionally, take anti-static precautions such as using an anti-static wristband and mat to prevent damage to electronic components.

    • Use the point of a spudger to push on alternating sides of the CMOS connector to "walk" it out of its socket.

    • It may take a lot of alternating before the connector comes out. Be patient, and don't pull on the cables.

    • To reconnect the cable, align the connector and use a spudger or clean fingernail to push it fully into the socket.

    • Don't push on the cables themselves, or you may damage the connector.

    • Slide the I/O board out from edge of the laptop to remove it.

    • The CMOS battery was also removed with the I/O board in this photo. It is held on with a small amount of adhesive. It is not necessary to remove the CMOS battery for this repair.

Conclusion

To reassemble your device, follow these instructions in reverse order. Take your e-waste to an R2 or e-Stewards certified recycler.
