Applicable Products: Notebook, Desktop, All-in-One PC, Gaming Handheld, MiniPC


A memory card (SD card) is a widely used storage medium in devices such as digital cameras, smartphones, and computers. Sometimes, you may encounter issues with memory cards, such as the card reader not detecting the memory card or errors occurring during reading or writing. In this article, we will provide some common troubleshooting methods to help you resolve these issues.

There are several different types of memory cards, including standard SD cards, miniSD cards, and microSD cards. Before using a memory card, please ensure that your device supports the specific memory card format. You can check the supported memory card formats on the ASUS product specification page on our official website or in the product user manual. If you are unsure how to download the user manual, please refer to this article: How to Search for and Download User Manuals.



Unlock the Memory Card

Some memory cards have a read/write security switch. Before using the memory card, make sure to set this switch to the unlocked position.


Check the Memory Card

Ensure that the memory card is correctly inserted into the device and check for any loose or improper insertion.

Try inserting another memory card of the same type into the device to ensure the problem is not due to a damaged memory card.


Clean the Memory Card Contacts

Gently wipe the metal contacts of the memory card with a soft cloth or eraser to remove any dirt or oxidation.


Check the Card Reader Slot

Try inserting the memory card into another compatible device to ensure that the issue is not due to a damaged card reader slot.

If the card reader slot is clogged with dust, try cleaning it to see if the problem can be resolved. When cleaning the memory card slot, make sure to turn off the device and disconnect the power cord. You can use a commercially available cleaning brush or an air blower to remove dust from the slot.


Restart the Device

Sometimes, restarting your device can resolve the issue.
