If a device is listed with a yellow exclamation mark in Windows Device Manager In Dell Laptop

A yellow exclamation mark in Device Manager indicates that Windows has detected a problem with the device. Most device manager errors can be resolved by uninstalling and/or installing the latest device driver.
  • Press the Windows logo key + R key on the keyboard.
  • In the Run dialog box, type devmgmt.msc and press the Enter key.
  • In Device Manager, locate the device that has a yellow exclamation mark.
  • Right-click the device and click Uninstall.
  • In the Confirm Device Uninstall window, check the box Delete the driver software for this device (if available).
  • Click OK to confirm and proceed with uninstallation.
  • Once the uninstallation is complete, reboot the PC.
Once the PC has rebooted, Microsoft Windows will automatically detect and attempt to reinstall the device driver. If the red X still remains after the reboot, depending on the device, download and install the device driver from Dell Drivers & Downloads website or the device manufacturer's website.

Refer to the informational videos section in this knowledge-base article for a video guide on how to download and install the latest device drivers from Dell Drivers & Downloads website.
