This guide will show how to replace the daughterboard on the Asus Zenbook UX31A laptop. This daughterboard contains the SD card slot, headphone jack, and USB port. This may be necessary if you are unable to connect external devices to your computer.
The connection card is responsible for allowing the computer to read and communicate with external hardware. If your card is having issues, the ports on the right side of your computer will not connect to external hardware.
Before following this guide, try connecting other cables and devices with the same port. If other cables or devices are able to connect, you may be having an issue with a cable or device that needs to be replaced.
Before you proceed, make sure to power the computer all the way down and disconnect the charging cable. Replacing the connection card will require the removal of the battery and fan.
