Aug 07, 2015. My Dell Inspiron 15r 5520 laptop running Windows 10 Home is. Graphics 4000 driver to the. I applied windows 8.1 drivers for dell inspiron.

I have a Dell Inspiron 15r 5520 laptop that is running Windows 10 Home and is not able to adjust it's screen brightness. This has been an issue even before I have upgraded to Windows 10. It was even there for sometime when I was using Windows 8.1. These are the solutions I have tried multiple times, but have not worked: • Using the FN brightness hot keys. • Using the charms bar brightness slider (Windows 8.1). • Updating the Intel HD Graphics 4000 driver to the latest version using device manager. • Disabling then enabling the Intel HD Graphics 4000 driver using device manager.

• Uninstalling then reinstalling the Intel HD Graphics 4000 driver using device manager. • Updating the Intel HD Graphics 4000 driver to the Microsoft Basic Display Adapter using device manager. • Using Dell System Diagnostic Test/Tool online and ran a Complete Test, but passed everything. The Control Panel manual brightness adjuster is not showing up and neither is the brightness slider in the battery icon in Windows 10 and Windows 8.1. Thank you in advanced.
