Keyboard misbehaving!

I have a Logitech K520 keyboard/mouse combo, connecting to my PC by Bluetooth via a tiny dongle. Firstly. Quite inexplicably, @ and " have for some obscure reason, transposed themselves. I always have to press one to get the other. Both symbols are Shift typed. The non shift 2 and ' on the same two keys, work perfectly normally. And now my Alt Gr has stopped functioning altogether! I do prefer my Latte and Pate to be spelled correctly!
I don't honestly expect anyone to solve the problem. Just having a moan, really!

 

I would first check another keyboard to see if the problem is still there, and I have read , while researching keyboard problems that if you have a ps/2 keyboard and go to a usb keyboard, sometimes the usb keyboard will have partial problems with some keys.

 

Bit of a delay in answering, due to family considerations. Would you believe it? I had a perfectly good, working usb keyboard that I gave away to a charity shop about a month ago! Always the way.

 

I believe that is one of the laws of nature,

You will never need something as much as the item you just threw away.

Never say never, you will find yourself doing the same action again.



Have you found another keyboard to test the issue with?

 

Not yet. Might be another trip to the 2nd hand shop again.

 

let me know, I will help if you find that the keyboard has the same issues.
