Hello All, Trying to find a 'slightly more official' answer to my problem than what Google feels like serving up to me right now. Have a Dell XPS 17 laptop - just been rebuilt with a new install of windows 7 x64 and it tells me there is an unknown device. The description of which is so vague as to be almost meaningless. I tried searching the one thing that might narrow it down 'microsoft acpi-compliant system' but that leads me to websites I don't really know well enought to trust downloads from. Based on that anyone know what I'm looking for in terms of a driver?

Fsc math part 2. Product not tested for Windows 10 upgrade Dell is not testing or developing Windows 10 drivers for this product. If you choose to upgrade, some features, applications, and connected devices may not work as expected. Acpi Smo8800 1 Dell may sometimes be at fault for other drivers ceasing to function These are the driver scans of 2 of our recent wiki members* *Scans were performed on computers suffering from Acpi Smo8800 1 Dell disfunctions.

There is nothing physical installed in the laptop besides what Dell shipped. Edit: Info I should have included.

Have been to Dell's site with the service tag - none of the 'filtered' drivers helped, and several from the 'all' have been tried also with no success. Removing it from Device manager it reappears as unknown and provides no extra details.

First, the ONLY driver for optical drives of any type is the default built in Windows driver. It has been this way since Win XP.

Since Linux detects it, this says its probably not disabled in the BIOS, although I would still check as Linux can do strange things. If its disabled or not detected in the BIOS, Windows will not detect it. Dell Calls the BIOS the 'Setup' and its accessed by F2 at power on. If the BIOS is OK, reinstall the Intel motherboard chipset drivers - even if the version you have is the latest. One of the things the chipset drivers do is identify all the devices on or attached to the motherboard. There are chipset drivers on the Dell downloads but they are old. You can get the latest at.

Hello, Thanks for the suggestions. The DVD drive looks fine. As I said, it's no problem when booted to Linux, but anyway I ran the BIOS diagnostic tests and they came up clean. And, the laptop will boot to both the Win 10 and Linux install DVDs.

I've updated the BIOS from A10 to A16, and the Intel Chipset to 9.2.0.1030 A05. When I tried running the HECI Driver update it generated an error message: 'This computer does not meet the minimum requirements for installing the software'. When I tried running the DVD Firmware update it generated the error message 'Drive can't be found' (I guess that's as you'd expect!). I found these drivers via the Dell Product Support Drivers & Downloads page.

I think I understand the basics, but the one thing I'm not clear on is how to determine the currently installed version numbers.? I also downloaded and ran the Intel Driver Update Utility Installer, but it found nothing at all. Should I have been searching manually, and if so, what should I have been looking for?
