Dell XPS 400 “Unknown Device”
Recently, I rebuilt a Dell XPS 400 and there was one pesky device in Device Manager that I couldn’t find a driver for. I tried searching Google by the device instance ID (ACPI\AWY001\2&DABA3ff&0), but mostly found other people with the same problem.
Finally, I stumbled upon this post on Dell’s support site. Austinpctech provided the link to the driver for Intel’s Quick Resume Technology: http://bit.ly/v8KDEw
