Check EDP Cable On Yoga 520
If none of the above steps have worked to fix the touch screen not working, there is one last thing to try before sending the laptop in for a display replacement.
Open the back cover of the Yoga 520 and check the EDP cable. This is simply the display connector from the motherboard to the display itself.
- Follow the cable and check for crimps or damage.
- Check the connection into the motherboard to ensure it fits tightly.
TIP: One user put a small folded up piece of paper over the connector so when the back cover was re-installed, it applied extra pressure to make sure the connection was tight.
Remove Yoga 520 Back Cover
Removing the back cover of the Yoga 520 only requires unscrewing 10 screws and lifting up the cover. See the diagrams below on the process.
If after following all the steps above your Lenovo Yoga 520 touch screen is not working still, it is time to call support for a repair and display replacement. Many people find a combination of device driver updates and/or software fixes fix their issues. But I have to note that there are too many Yoga laptops with defective touch screens. Hopefully, you have found a solution to get your working again.
