HP ProBook 455 G7 SSD Replacement

Introduction

This guide will help you replace the hard drive in the HP ProBook 455 G7 (Model: 7JN02AV). This model can be configured with a SATA HDD or SSD, which stores your operating system, files, applications, and recovery partitions.

You may need to replace the hard drive if you experience symptoms like frequent crashing, slow performance, clicking noises, or boot errors. If you’re unsure, refer to the “Storage or Boot Issues” section of the Troubleshooting Page.

Before starting, back up any important data, as removing the hard drive will erase access to all stored files. Make sure the laptop is powered off and unplugged.

If you are upgrading to an SSD, HP’s support site provides migration resources that may help transfer your OS.
