![]() The two that remain have the following Hardware IDs: First Unknown Device: ACPI VENCPLDEV0002 ACPI CPL0002 CPL0002 Second Unknown Device: ACPIVENKIOXDEV0095 ACPIKIOX0095 KIOX0095 - When I run the automatic detection tool, it says No driver updates found.Īfter 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.įor 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.Ĭan anyone tell me where I can find Windows 10 drivers for these unknown devices Basic Measuring And Layout Tools there. I cannot find any ACPI drivers to remove this unknown device problem in windows 7.ĭoing this took care of all of the Unknown Devices that are listed in Device manager except for two. ![]() If that doesnt work, please go to the official site to download and install the drivers. DELL Inspiron MACPI Driver Utility updates your Windows 7 ACPI drivers, based on the scan, and matches to the latest most compatible versions. At this writing, Windows 7 is not supported yet (I confirmed for 64 bit version is not supported). We have to use the device management software for updating the ACPI Compliant Control Method Battery drivers. The Smart Battery installation only support Windows XP 32 bit, Windows Vista 32 and 64 bit only.
