Certain keystrokes producing multiple characters
My keyboard has started malfunctioning where every time I press certain keys, I get two characters instead of the single character it ought to be. Here are the character sets being affected
For example, when I press '5', it produces '56', and the same when I press '6'. It too produces '56'. Same for the whole list above.
Note too the apparent pattern down the keyboard with the '56', 'ty', 'gh', and 'bn' combos.
I've checked battery level. It's nearly full charge. I've tried using while plugged in and charging. I've tried gently lifting affected keys and blowing out any possible dust, particles, etc. None of this has helped.
Is this a good question?
