From: Mike on 9 Apr 2006 19:54 Hi everyone, I just bought the HP Pavilion a1340n, it came with Windows XP Media Center Edition. I reformatted the hard drive and install Windows XP Professional SP2. I installed all the necessary drivers for this PC and everything seems to be working okay, but under Device Manager it shows one device that is "Unknown Device" This Unknown device is listed under Other Devices category. Before I installed XP Professional, I wrote down all the listing and categories of the Device Manager within Windows XP Media Center Edition. After I installed XP Professional SP2 I compared the listings under Device Manager of XP Professional and XP Media Center edition, beside the one "Unknown device", the listing under XP Professional also missing the ARPC Devices category which shows under XP Media Center Edition. Here is the comparison between Windows XP Professional and XP Media Center Windows XP Professional SP2: ? Other Devices ?! Unknown Device Properties - Location: on PCI standard ISA bridge Details: ACPI\AWY0001\4&1EC577C0&0 Windows XP Media Center: - APRC Devices - MS ArACPI Driver Properties - Location: on PCI standard ISA bridge Details: ACPI\AWY0001\4&1EC577C0&0 MS ArPolicy Driver As you can see from these two listing, the Unknown Device is the MS ArACPI Drive. I've been trying for the last 3 days trying to find where I can download this MS ArACPI Driver. Does anyone know what is this MS ArACPI Driver and does it supports Windows XP Professional? I also uninstall/reinstall all the drivers, but nothing helps. So far HP Support will not help me because they told me that because this PC came with Windows XP media center and I installed Windows XP Professional. They only support the original operating system that came with the PC. Here is the following hardware components for my PC. HP Pavilion model a1340n. Inside the computer is untouched. CPU: Intel Pentium 4 3.2 GHz Memory: 1 Gig Ram hard drive 250 Gig SATA DVD: Lightscribe DVD Writer Graphics: Integrated ATI Radeon Xpress 200 series Modem: Agere Systems Softmodem Audio: Realtek High Definition Audio 9-in-1 (4 slot) + 1 USB memory card reader And again, I have installed all the necessary drivers including the motherboard chipset driver and compared the Device Manager settings from XP Media Center and XP Professional SP2 and it is the same except for those noted above. Thank you very much in advance. Mike

When I started to dig, I found this site: http://www.versiontracker.com/dyn/moreinfo/win/53395 The download link is directly from MS. I am going to try that now.

From: doeppel on 9 May 2006 17:01 ok I just found this on Microsoft which lists all the files that were listed under WMC. So it has to do with the Away mode functionality... Dave
