The Lenovo Yoga 520 is a versatile 2-in-1 laptop favored by many for its sleek design and powerful performance. However, like any technological device, it can encounter issues that disrupt its functionality. One common problem users face is a non-responsive touch screen. This article delves into the reasons behind a malfunctioning touch screen and provides effective troubleshooting steps to restore its functionality.
Understanding the Touch Screen Technology
Before diving into troubleshooting, it’s essential to understand how touch screen technology works. The Lenovo Yoga 520 employs capacitive touchscreen technology, which allows users to interact directly with the displayed content through touch.
The Basics of Capacitive Touch Screens
Capacitive touch screens operate by detecting the electrical properties of the human body. They typically consist of a glass panel coated with a conductive material. When a finger touches the screen, it creates a disturbance in the electrostatic field, which the device interprets as a command.
As a result of this technology, different issues can affect the functionality of the touch screen. Understanding these issues can assist in quickly diagnosing the problem.
Common Reasons for Touch Screen Malfunctions
When you encounter a non-working touch screen on your Lenovo Yoga 520, various factors could be at play. Below are some of the most common reasons behind touch screen malfunctions.
Software Glitches
Software issues are one of the primary reasons for touch screen malfunctions. This can be caused by:
- Recent system updates that may have introduced bugs.
- Conflicts with third-party applications that interfere with screen functionality.
Driver Issues
Drivers are essential for the operating system to communicate with hardware components. If your touch screen driver is outdated or corrupted, the touch functionality could be impaired.
Hardware Problems
While less common, hardware issues can also cause touch screen malfunctions. Possible hardware-related problems include:
- A physical defect in the touchscreen itself.
- Connections that may have become loose due to wear and tear.
- Damage from drops or liquids.

What are the common reasons for my Lenovo Yoga 520 touch screen not working?
The Lenovo Yoga 520 touch screen may not work due to several common issues. First, hardware malfunctions can occur, such as a faulty digitizer or a disconnected cable that connects the display to the motherboard. Additionally, physical damage from drops or spills can affect the touch screen’s responsiveness.
Another reason could be software-related issues. Sometimes, outdated or corrupted drivers can cause the touch functionality to fail. Windows updates may also inadvertently affect device drivers, leading to touch screen problems. Checking your device for any potential software glitches is essential in troubleshooting this issue.
How can I restart my Lenovo Yoga 520 to fix the touch screen issue?
Restarting your Lenovo Yoga 520 can often resolve temporary glitches, including touch screen problems. To do this, simply hold down the power button until the device powers off. After a few moments, press the power button again to turn the laptop back on. This process helps in clearing the system’s memory and can eliminate minor software issues affecting the touch screen.
If the touch screen still does not respond after restarting, consider performing a hard reset. Disconnect all peripherals, unplug the charger, and then press and hold the power button for about 10-15 seconds to fully drain residual power. After this, reconnect the charger and turn on the device again to see if the touch screen is functioning properly.
What should I do if the touch screen is not responding at all?
If your touch screen is entirely unresponsive, you may want to check if the device is in tablet mode. Sometimes, entering tablet mode can affect touch screen functionality. On the Yoga 520, you can switch between laptop and tablet mode by pivoting the screen. Ensure that the device recognizes the mode change and test the touch screen again.
If the screen is still non-responsive in both modes, it may be time to check for driver issues. Right-click on the Start menu, go to Device Manager, and expand the “Human Interface Devices” section. Look for “HID-compliant touch screen” and right-click it. Select “Enable” if it’s disabled or “Update driver” to download the latest version. Restart your laptop afterward to see if the touch screen is working again.
How can I check if the touch screen hardware is functioning properly?
To check the hardware functionality of your Lenovo Yoga 520 touch screen, you can run a built-in diagnostic tool. Lenovo devices often come equipped with Lenovo Vantage software, which can help you diagnose hardware issues. Open Lenovo Vantage, navigate to the “Hardware Settings,” and look for touch screen diagnostics. Running this test can identify if there are any underlying hardware problems that need addressing.
If Lenovo Vantage indicates the hardware is functioning correctly, you may consider performing a more thorough hardware check. Inspect the device physically for any signs of damage, such as cracks or water damage. Additionally, ensure that all connections are secure, especially if you’re comfortable opening up the device to check internal components.
What do I do if my touch screen driver is missing or outdated?
If your touch screen driver is missing or outdated, you can resolve this by accessing Device Manager. To do this, right-click on the Start menu and select “Device Manager.” Look for the “Human Interface Devices” section. If you see a yellow exclamation mark next to the “HID-compliant touch screen,” it indicates a driver problem. Right-click on it and choose “Update driver.”
Another option is to visit the Lenovo support website, where you can download the most recent drivers for your specific model. Make sure to download the touch screen drivers and install them on your device. After completing the installation, restart your laptop to apply the changes, and check if the touch screen is working properly again.
Could a system restore help fix the touch screen issue?
Yes, performing a system restore may help in fixing touch screen issues on your Lenovo Yoga 520, especially if the problem started after a recent software update or installation of new programs. System Restore allows you to revert your device to a previous state when the touch screen was functioning correctly. To access this feature, type “System Restore” in the Windows search bar and follow the prompts to choose a restore point before the issue began.
However, be aware that restoring your system will undo any changes made after the selected restore point, including installed applications or updates. It’s a good idea to back up important data before proceeding with a system restore. After completion, check the touch screen functionality to see if the issue persists.
When should I consider contacting Lenovo support for my touch screen issue?
You should consider contacting Lenovo support if you’ve tried all the basic troubleshooting methods without success. If your touch screen remains unresponsive despite efforts, such as restarting, checking drivers, and running diagnostics, it may indicate a more serious hardware problem. Since the Lenovo Yoga 520 is a portable device with sensitive components, professional assistance may be necessary to prevent further damage.
Additionally, if your device is still under warranty, reaching out to Lenovo support could be beneficial. They can provide specialized troubleshooting and arrange for repairs or replacements if necessary. Ensure that you have your device information and warranty details ready for a quicker and more efficient support experience.
