Unknown Device - Missing Driver (ACPI\VEN_AOA&DEV_2011)

I just bought an Ideapad U410 Touch laptop and reinstalled Windows 8. Now it says that one of the devices is unknown and missing drivers.

 

I can't figure out what this device is and which driver should I install.

 

The device is this ACPI\VEN_AOA&DEV_2011

 

Thanks for your help, Nik

Just install all pertinent drivers for your model from the support site. You click Support, Drivers & Software, Laptops & Tablets, select the series and locate your model number. Click submit.
