So after reading a lot about how to run the report and open it (yes it does not open from the CMD prompt) I was able to find the PCI vendor and device code and ascertain I have the latest drivers from those manufacturers (Gigabyte and ALI). Mainly the USB Root Hub and the USB Mass Storage items. Strangely my Win 7 does not have a "Power Management" tab for these items and the "codes" PDCAP_D0_SUPPORTED PDCAP_D2_SUPPORTED PDCAP_D3_SUPPORTED Don't mean anything to me. So now what? The Computer used to sleep and nothing changed to justify not sleeping anymore. Can anyone help, please?
