Unknown device on Microsoft ACPI-Compliant System ACPI\AWY0001 \Device\00000040

I upgraded a HP Pavilion a1268c to Windows 7 64bit and am getting this in the device manager. Any help to locate drive is appreciated. HP has no driver downloads and my recovery discs are for Windows XP.

 

Would love to solve this issue.

Hi,

 

Try running this Intel Driver update utility.

 

If the fails, then try installing the NVIDA Windows 7 64 bit nForce driver .  If you need Windows 7 32 bit look here.

That did not work. The system has an AMD64 Athlon x2 processor if that helps

Hi:

 

Windows 7 does not need the actual driver for the device to work.

 

Download and Install this driver and it should work...

 

http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS008944

 

If for some reason that driver doesn't work, here is the link to my skydrive folder...

 

Download and unzip the file labeled Awy.

 

Go to the device manager and click on the ACPI\AWY0001 device needing a driver.

 

Click on the driver tab.  Click on Update driver.  Select the Browse my computer for driver software method and browse to the driver folder you unzipped.

 

Make sure the Include Subfolders box is checked and the driver should install.

Apparently I am running a 32bit uninstaller of NVIDIA on a 64bit system.

 

Is this something I do not need to worry about?

You're very welcome.

 

The Lenovo site specified the drivers were for both bit versions.

 

But I disassembled the driver, and it appeared it only had the setup info for 32 bit operating systems, so I gave you the link to the 64 bit driver I knew would work.

 

I forgot I had it tucked away.  :generic:

 

For some reason, I can't attach small files to my replies like I usually can.
