Hi Melissa Ingaruca Moreno,
Thank you for reaching Microsoft Community. I understand that you are experiencing issues with the built-in SD card reader on your Surface Book 2. I'm sorry to hear that you have already tried some troubleshooting steps, but the issue still persists.
Based on the information you provided, it seems that the issue is not related to the Windows update or any new programs that you have installed. Since the SD card works on other laptops, it is likely that the issue is with the Surface Book 2's SD card reader itself.
Here are some additional troubleshooting steps that you can try:
- Check for any physical damage on the SD card reader. Make sure that there are no debris or dust particles that may be blocking the connection.
- Try using a different SD card to see if the issue is with the card itself.
- Check devices in UEFI settings. Boot your Surface to its UEFI environment by following the steps provided here: How to use Surface UEFI - Microsoft Support. Once you are on the UEFI menu, go to Devices tab. Check if the Docking USB Port and Accessory Radio Port options are enabled. Enable them if not. If they are already enabled, disable them first then select Exit > Restart now. Boot back to the UEFI menu then re-enable the devices.
If in case the issue persists, kindly open Device Manager, click View and select Show hidden devices then see if the Memory technology devices appears. Check also under Disk drives section in Device Manager if the SD card card shows up under that section or not also.
Let me know how it goes.
Kind regards,
Marrion
