Introduction
Go to step 1 ↓This guide explains how to replace the SD card reader module in the HP ProBook 455 G7 (Model: 7JN02AV). The SD reader is responsible for reading media cards used for storage, file transfer, and camera imports.
You may need to replace this part if your laptop does not recognize SD cards, disconnects frequently, or physically damaged pins are visible. See the “Port or Input Issues” section on the Troubleshooting Page for related symptoms.
Make sure the laptop is powered down and disconnected from power.
Be careful not to bend the SD reader pins or force a misaligned connector into place.
