Sometimes only way I can wake computer up is by changing usb port for mouse or keyboard, or disconnecting ethernet cable

Windows 11

When computer goes to sleep, sometimes I cannot wake it up when I click on the keyboard.

After trying many online suggestions to resolve this, I found that often, but not always, I can wake it up by doing one of the following;: change USB port for the mouse; change USB port for the keyboard,  or disconnecting the ethernet cable.  Sometimes one of these 3 options will work, but later that option will not work.  I think,  but am not sure, that I once removed the wire connected to my speakers, and that woke the computer up.

Any suggestions?

Thanks,

Mark
