When your Dell laptop went wrong, you checked your Device Manager found there’s an unknown device with the exclamation point in yellow. You wanted to uninstall/update it but failed. Don’t worry, we’re here to help.
This post will solve your issue by updating this “unknown” driver.
Why you need to update the driver
Drivers are software components that make devices and the operating system talk to each other. Both system and device are updating to catch up with the changing world, so is drivers. If the operating system changes the way it speaks to devices and drivers haven’t updated, devices can’t receive correct commands and cause problems.
That’s why when you meet problems, you need to download the related driver to solve it.
