Strange, but the keyboard now wakes the computer after a Windows Insider update this morning. I cannot imagine how this solved a problem that had lasted for weeks but it has, at least for now.
The standard HID keyboard with a new Dell XPS 8940 will not wake the computer from sleep. An older identical Dell standard HID keyboard wakes the computer. Both have identical latest drivers. Both have checked "allow this device to wake the computer.". The mouse wakes the computer. Switching USB ports does not solve the problem. Any ideas? I get by ok using the mouse but still wonder what may be the problem.
