I seem to have fixed a similar problem with USB (or any) wake up; where the problem was apparently caused by Windows Update, since that was the only variable at the time the problem manifested. To fix, I went to Control_Panel --> Power_Options --> USB_Settings -- USB selective suspend setting : Disabled. I can't tell you what this does, (Microsoft gibberish prompts,) but afterwards, I was able to use keyboard to get out of "sleep".
On another forum, I read about Device_Manager --> Universal Serial Bus controllers --> USB Root Hub [all, individually] --> (double click for "Properties") --> (Select tab) Power Management --> (Uncheck) Allow the computer to turn off this device to save power.
At the BIOS level, apparently there is S1 versus S3, where S3 is supposed to be more comprehensive because it turns off fans, and such. Saw some comments that S3 doesn't really exist. There are generally some controls in the BIOS about sleep/wake; I have no idea how they should be set.
Anyway, preliminary tests indicate that I can "wake" with my keyboard again. So far only limited tests, and only with "sleep", not "hybernate" yet. We shall see. I probably will not return to this forum to update with test results, so you are on your own.
I tried resetting (again):
- My Power Options (restored default settings)
- Any USB device that had a Power Management tab (in Device Manager)
It made no difference.
My PC seemingly turns all USB devices off when it is in Sleep mode.
The settings must have to be set in a specific order (BIOS, Device Manager, Power Options, etc.).
@lehnerus2000
Have you tried disabling usb selective sleep? Also which USB ports are your keyboard and mouse plugged into? The back or front? Where on the back if so?
I have my PC set to that option (USB selective suspend setting > Disabled).
I just tested both options, but there was no difference (i.e. it still wouldn't wake).
I think that the issue is caused by something "higher up the chain of command".
I have the keyboard and mouse plugged into an USB expansion panel.
The two ports plug into the motherboard (via cables).
The keyboard and mouse were previously (at different times) plugged into a rear USB port, which is directly connected to the motherboard.
That is why. You have them plugged into a usb expansion panel. Plug them directly in and you should not have any issues.
Or are you saying even directly plugged into the back usb ports on the motherboard it still doesn't work?
It's annoying.
Mostly because I don't know the answer.
It should be easy to make this basic function work (pressing the Power button is a minor annoyance).
It's taunting me. I want to know why it isn't working.
I never had these issues with PS/2 peripherals.
I think the most work I was ever forced to do, was to change a BIOS setting.
@OriginalAIX thank you for the help.
I did not know there were power settings for USB Hubs in Device Manager.
I have recently installed / upgraded Win 7 on 3 pc's (some old some new) and could not get mouse to wake the pc.
Disabling the power saving on internal USB Hubs has fixed the problem.
