COMPUTER KEYBOARD REPEATEDLY / RANDOMLY TYPES CHARACTERS ON SCREEN / DOCUMENT AND / OR IN FIELDS
computer started displaying random and repeat characters on any document / field
I had open. Specifically it was primarily the digit '8', but occasionally would
be a '9' or '7'. It was intermittent and random. At first I thought it was...
This is simply what we experienced and found recently and may or may not reflect on your specific cause. Recently my computer started displaying '8' repeatedly and randomly,
We have two keyboards connected to our 'desk-top' PC. A 'wired' Microsoft 'Natural', 'Multi-media' keyboard 1.0A and a 'wireless' Microsoft 'Natural', 'Ergonomic' 7000 keyboard via the USB Microsoft Wireless 2.4Ghz v1.0 dongle (that's on my 'walking / treadmill desk'). New build computer, running Windows 7.
When I first saw the symptom, I immediately started running a full AVG anti-virus scan. After a brief look on the web (somewhat difficult to do as it was trying to type over me) it started 'not' pointing to a virus. After skimming a couple of posts, I pulled out the wireless dongle / receiver for the wireless keyboard and the symptom seemed to stop. I then replaced it, and the random character generation resumed. I then pulled the batteries from the keyboard and it stopped. I was thinking another possibility, but remote, that someone was 'hi-jacking' thru the wireless dongle (don't even know if that's possible, but I do know it's possible to capture keystrokes from a wireless device).
I then tested the AA batteries and found them to be approx 1.3V (just FYI, that's NOT good. A 'fresh' 1.5V / AA battery will register about 1.62 to 1.63V. Once it gets down to 1.5V, it usually will fail pretty quickly. Replacing the batteries seemed to be the fix. If it seems to be something further, I'll update this posting. Till then, fingers crossed....
