Keyboard no longer able to wake computer from sleep
I have Microsoft ergonomic KB, model 4000 v1.0 (15 years old), running on Win 10 Pro system, version 2004.
I have configured powercfg to enable wake on KB. For the past few years this has worked. It was plugged into the back of my desktop computer.
The other day I unplugged KB and put it in a different USB port in a hub. KB wake stopped working.
DeviceMgr shows me that the KB is "HID Keyboard Device" and "Allow device to wake computer" is enabled.
Furthermore powercfg -devicequery wake_armed confirms that the KB is enabled to wake. Yet it does not.
I've put the KB back in the port that it was originally in and power cycled computer, yet it still fails.
The only way to wake is to briefly click the power button on the computer (fortunately this does not turn it off).
Any ideas? Help please!
