Actually that is Lenovo Smart Connect (Update), the driver file is missing in the support site. It is found on the Lenovo China Support Site.

The link to the file is:

http://driverdl.lenovo.com.cn/lenovo/DriverFilesUploadFloder/35350/SmartConnect.exe

This is for both Windows 7 32bit and 64bit Edition.

File Size: 4.74 MB

Version:1.0.29

Hi!

 

I've just installed my new S400 with Win7 Professional 64-bit and there is the same problem with the unknown device. But when I try to install the above mentioned Setup I only receive the message "This machine is not Lenovo, Smart Update quit.".Smiley Frustrated

 

Has anyone an idea how to fix the problem?

Re: S400 missing ACPI\AOA2011 driver

I have to same problem with my Ideapad S300. I tried several times to reinstall Windows again. When I installed it into SSD then it worked. Anyway 24gb is not enough for Windows 8 so I tried to install to HDD. First time with UEFI then I tried without UEFI. Both time I can't install last driver ACPI\AOA2011

do you have any idea what it should be? I download Lenovo smart update from different location because the original one wrote me the same problem like SideWinder80 that "This machine is not Lenovo, Smart Update quit."

Betreff: S400 missing ACPI\AOA2011 driver

Hello!

 

Problem "Missing ACPI\AOA2011 driver"?

 

Ok, I have now registered to write you. ;-)

 

The solution is: You will need the drivers "Always Online Always Connected Driver".

"Lenovo Corporation, Lenovo AOAC driver"

 

The package is very small and contain 3 small files. (LAD.inf; LADx64.cat, and in direcory "x64" the file LAD.sys)

 

1. Search the driver (I can not upload the driver here)

2. Go to the device and select "Locate driver on this PC"

3. change to the directory where the file "LAD.INF"is located.

4. Click ok and the driver is installed.

 

Sorry for my bad English

 

Greeting
