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

Thanks for your help, I installed the driver but the problem still exists.
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.

I did a clean install of Win 8.1 and installed ALL available drivers from the support page. Apperently still one is missing,
This is listed unter hardware IDs:
As I said: All drivers are installed
Solved: It was the Lenovo AOAC driver, which is not listed.
