I have a similar issue to Logitech wireless keyboard won't type anything -- reloaded, but in my case the issue is not isolated to Windows or the USB receiver, and it only happens with the '7', 'r', 'i', '[', ';', 'f', 'a', 'Caps Lock', 'z', '.' and 'Spacebar' keys.

I first noticed the problem on my MacBook Pro about a year ago and have since confirmed that it happens on my Windows 10 laptop too. I have tried:

• Connecting via both the Logitech Unifying Receiver and Bluetooth, with the keyboard right next toone laptop after the other and a USB charger plugged into it - makes no difference.
• Uninstalling the Logitech Unifying software completely, restarting and allowing the OS to install a generic driver (on both laptops) - no change.
• Reinstalling the above software - it won't pair with the device (never did), but it shows up in the 'Advanced' section (on both laptops).
• Turning on/off 'Filter Keys' in Windows - no change.
• Disassembling the keyboard and inspecting the circuit board and ribbon cable for damage - didn't notice anything obvious, but my eyes or inexperience with diagnosing hardware issues at this level may have deceived me.

The keyboard is quite old - I'm not sure exactly when I bought it but definitely beyond the 1 year warranty period - however I've hardly used it and have always been careful with it. This means no drops from a great height, no spilled liquids and nothing else that would obviously cause such an issue IME. I have dropped it from small heights quite a few times, but only on to soft surfaces, never concrete or anything like that.

Is there anything less-obvious that I'm missing?
