Finding a Driver for an 'Unknown Device'

Hi!

tions

I recently purchased the M17x R4 Alienware Laptop. When I received it I did a clean install for Windows 7 Professional. I installed all the drivers in the Resource Media DVD, updated said drivers with those I found on the dell support site and also updated the graphics driver from the AMD website. I then ran through windows update and did all the necessary stuff there. Played a few games and tried using various programs to test my new setup; everything appeared to work fine and dandy.

Then I downloaded AlienAutopsy just to make sure ever was fine and dandy and to see if I forgot anything. Ran the hardware test and everything was okay but then I notice the assessment that my system needed 'attention' and found that it detected 1 device without a device driver. I looked up the hardware ID for the unknown device and it came up with:

"ACPI\CPL0002" and was listed in the category of "other devices".

I did a quick google search for this hardware ID and found no relevant results. There were a few IT forums that had "suggestions" for what it might be but none that could say for certain. Among those suggestions included "Chipset Drivers" (I reinstalled all the chipset drivers on the dell support website just in case, but the device still showed up as "unknown"), "Smartbattery Driver" (I Installed from the Intel site as it was not listed for my computer on dell support, but still device showed up as unknown) and lastly some people thought it was the Freefall Sensors but I again reinstalled this from the dell support site and still no luck.

Would anyone have any idea what this device might be?
