The third symptom suggested that maybe Windows Sticky Keys was the culprit.

Holding down the Shift or Ctrl key seems to initiate the second symptom above sometimes-but not reliably.

Sometimes in the midst of typing a word, Windows makes a USB device disconnected sound and for a moment does not register keyboard input.

The number lock LED turns off after a few seconds of not typing.

Immediately following the symptoms section are step-by-step instructions on how to remedy them. Thus, this blog post: because from Bing and Google searches I know that many other people have had this problem, and yet there doesn’t appear to be one good article out there with this fix-not even by Microsoft Support!īelow are the symptoms my Microsoft Wired Keyboard 200 exhibited in Windows 8.1. But a few days after implementing it, I can confirm that the solution definitely works. I also could not figure out a solution until now (five months later). The keyboard seemed to randomly disconnect and reconnect throughout the day without rhyme or reason. In other words, this was a virtually perfect keyboard.

The cost was also nominal: less than $13 on eBay.

It was a Microsoft Wired Keyboard 200: a classic-dare I say iconic-keyboard, the type that features 104 keys that are predictably and ergonomically laid out and has three LEDs to indicate the status of number lock, caps lock, and scroll lock. When I built my super fast workstation computer in October, I got it a clean new keyboard that matched the rest of my arsenal of electronic products adorned with the logo of Redmond, Washington’s finest company.
