Windows 7: Fails to wake from Sleep

Fails to wake from Sleep

Windows 7 pro, desktop, 2 internal sata hd

Read most of the many threads on this subject. I have turned off Sleep using Control Panel, Editing the Registry, disabling hybrid computer as described in this forums tutorial.

The Start/Sleep button is not grayed out and still shuts down the computer although the automatic timed sleep mode seems to be eliminated. Moving or clicking the mouse does not wake up the computer as originally. I have to remove the power cord for a few minutes and then press the power button. I think the computer then comes back up w/o the windows sign-on window as if awakening from Sleep. Windows 7 initializtion is very slow.

Problem with Sleep arose after installing an external drive enclosure with a sata hd and using the esata interface which did not work and caused loss of 2nd internal hard drive.

I do not mind the automatic sleep mode if the computer would awaken properly.

Forgot to mention the following: Even though the Sleep recovery does not work, the computer responds to Restart and turn on from power shut down normally in its usual quick fashion.

After running Powercfg -energy suggested bySaltgrass

The report showed several USB errors: ie, wireless keyboard and mouse
I had to read the html file directly from Notepad since neither of my browsers could find the file even though I gave the path to the file.

As far as I could determine, it did not lijke the device ID'd as 'Host Controller" on the PCI bus 0. Report said device did not go into suspend mode. Further id of the device is "PCI\VEN_8086&Dev_3B39" . The only device on the PCI bus is the Video Display Card.

I reconnected a wired keyboard and a USB mouse, disconnected the external hard drive enclosure and ran Powercfg - energy again. Same result: will not wake from clicking on Start/Sleep. The next report did not complain about the Wireless keyboard and mouse but complained about the above "host controller".

Still puzzled.
