Here's an interesting problem with a keyboard I present so you can learn from my mistake.
My mother rang up in a panic because the keyboard on her PC (an Intel NUC) wasn't working. I was busy and my first thought that was that the batteries had failed and asked her to change them. Despite it being a wireless keyboard she didn't realise that batteries were required! (Give her a break, she's over 80.) I was only half right. I rang back later to check and she hadn't done anything so I visited. Changing the batteries did not help, but now the letters appeared but slowly and the keyboard bleeped. I immediately twigged that Windows' Sticky Keys was now on. Turning that off resolved the problem completely.
What appears to have happened was that the batteries in the keyboard were low on charge and the PC had noted the problematic transmissions from the keyboard and decided to turn on Sticky Keys.
