Unknown device ACPI\AWY0001 *AWY0001 / Dispositivo desconocido AWY0001 / Périphérique inconnu AWY0001


FIX :
This unknown device is related to the AMD Away technology. This is basically a souped up sleep mode that is not needed in Windows 7, hence the absence of driver. Below you can download a null driver that will remove the unresolved hardware detection exclamation mark.  This driver should also works if you are using an Intel processor.

If the link is dead you can also copy the following text to a text document, save it as “AmdAway.inf”, and then follow the installation instructions below:
