Plugging the Unifying Receiver into different USB ports also doesn't change anything, nor does simply rebooting the machine.
Many recommend updating the device driver from the Device Manager, but the only keyboard listed is the corded Mac keyboard. Searching for this issue and trying the few suggestions doesn't yield any success.
Strangely enough, my spare Mac corded keyboard works just fine (and that's what I'm using to type this)… I tried using the keyboard on another computer and it works just fine, so it must be a Windows issue. The keyboard pairs correctly using the Unifying software and when I press a key on it, the icon lights up that the computer received input, but nothing happens. The function keys work (I can mute, change volume, etc), but I can't input any numbers or letters. Question: Q: Keyboard wont type letters Ive accidentally pressed some combination of keyboard keys that has caused my Mac mini's keyboard to no longer type letters. All of a sudden, the keyboard doesn't type anything.
Problems might occur on a laptop keyboard due to various reasons. 3 hours ago If the keyboard works but wont type after reboot, try another method to fix the issue. I have a Logitech K800 wireless keyboard and Performance MX mouse running off of the same Unifying Receiver on Windows 10. The keyboard is a very vulnerable component on the laptop.
