Introduction

The Hall sensor is used in laptops that don’t have a mechanical latch. It can tell if your laptop is closed or not. If the Hall sensor is not working, it may not tell the system to turn off when the screen is closed. If your Hall sensor fails due to corrosion, cracks, or breakage, you may need to replace it. Prior to beginning the repair, check out the Lenovo Troubleshooting page.

Make sure to disable the internal battery, power down your device, and disconnect from any external power sources before you begin.
