Acpi Cpl0002 Windows 7 And 8

I cannot find any ACPI drivers to remove this unknown device problem in windows 7.

After installing Windows 10, I used Dells online utility to detect drivers (or updates) appropriate for my system.

Doing this took care of all of the Unknown Devices that are listed in Device manager except for two.

After searching in the dell forums for posts related to similar issues, I believe that the first unknown device is related to an Alienware On-Screen Display Application and the second unknown device is related to a Kionix Free Fall Sensor Driver.

For both of these, the only drivers I can find on the Dell website say that they are supported for Windows 7 and 8.1, but not Windows 10.

Can anyone tell me where I can find Windows 10 drivers for these unknown devices Basic Measuring And Layout Tools there.

But when I put Windows 7 on, the energy driver works fine, but the CIR driver installs but the unknown device is still their.

Any other suggestions I have figured out that it is probably the Compal Embedded System Control but windows wont instal the drive on 7 I cant find the driver online to try run it in compatibility mode though, the dell ones available dont seem to be compatible.

Also the windows 7 beta driver list seems to only have drivers for thinkpads and not ideapads.

Is it possible that this only happens on the 64-bit os of Windows 7 Ive done some searching on google and several people have this problem with XP64 and Vista 64.

Do all of you have windows 7 64 bit installed Message Edited by trunksalan on 08-03-2009 02:22 PM.
