Introduction

If your HP Envy x360 m Convertible (Model 15m-cn0012dx) isn’t reading SD cards, use this guide to replace the SD card motherboard.

A faulty SD card reader will not even recognize that there is a card in the slot. It will not show up on the computer desktop screen.

Before starting, make sure all external connections are unplugged and the computer is turned off.
