The Lenovo Yoga series laptops, including the Yoga 3 11, Yoga 3-1117, Yoga 3 14, Yoga 3 Pro-1370, Yoga 4, Yoga 900-13ISK, and Yoga 700S-14ISK, typically feature USB ports on the sides or back of the device. These ports are used for connecting various external devices such as USB flash drives, external hard drives, printers, and other peripherals.
If you're experiencing issues with the USB ports on your Lenovo Yoga laptop, here are some troubleshooting steps you can try:
1. **Check for physical damage:** Inspect the USB ports for any physical damage, such as bent or broken pins, or dust/debris obstructing the port. If you find any damage, you may need to contact Lenovo support for repair options.
2. **Try different USB devices:** Test the USB ports with different USB devices to see if the issue is specific to one device or affects multiple devices. This can help determine if the problem lies with the port or the device itself.
3. **Restart your laptop:** Sometimes, a simple restart can fix minor issues with USB ports. Restart your laptop and see if the ports start working again.
4. **Update USB drivers:** Ensure that your USB drivers are up to date. You can do this through the Device Manager on Windows or by visiting Lenovo's support website and downloading the latest drivers for your specific model.
5. **Check power management settings:** In the Device Manager, under Universal Serial Bus controllers, right-click each USB Root Hub and select Properties. Go to the Power Management tab and uncheck "Allow the computer to turn off this device to save power" for each port. This can prevent power-saving features from interfering with USB device detection.
6. **Reset USB ports:** In the Device Manager, under Universal Serial Bus controllers, right-click each USB Root Hub and select Uninstall device. Restart your laptop, and Windows will automatically reinstall the USB drivers. This can sometimes resolve issues with USB ports.
If none of these steps resolve the issue, there may be a hardware problem with the USB ports, and you may need to contact Lenovo support for further assistance or consider professional repair.
