Shift keys not working with certain letters  

In my case, the on screen keyboard showed all is good.

The problem was one of the media keys that was stuck (not visible or noticeable).

After freeing it all returned to normal.

I signed up to say thank you as well. All the solutions I was finding before I got here were ridiculously complicated - I knew it had to be something simple. Thanks so much, and sorry to bump an old thread, but gratitude is due to you for your assistance!

Cheers,
Michelle

I had this exact same problem and the cause were the Play/Pause, Stop, Rewind, Fast Forward buttons where the multimedia functions are (volume, mute buttons etc) . I have a Logitech Media Elite keyboard.

After i cleaned the keyboard using my own special technique everything was fine, then i tried to reproduce the problem and held in some of the media keys that don't have any apparent effects (for example, if the Mute key was stuck i would have noticed it) like the Play/Pause, Stop and Fast Forward/Rewind buttons and tried to use the Shift + letters that didn't work last time and the same thing happened. So unstick the button and clean your keyboard.

This one worked for me. Thanks so much Solinari. You saved me from buying a new keyboard! Cheers :)

I have a similar problem with a new Logitech MK320. At times it goes into a mode where, with the shift key held down, certain keys don't print at all (not just don't go to caps): FGHKUR etc. In their support forum, someone else had the exact same problem (even the same keys) a year ago on an MK300.

Once in the mode, it acts like that consistently for hours. When I swapped to a brand new keyboard (same model) it had the same problem. I emailed Logitech support, who replied promptly, but their first set of suggestions is all things like wireless connection, that would affect all keys or none.

I think your answer may be the key. I use Mute, Vol+ and Vol- a lot, and I'm sure that I sometimes his the nearby Play buttons by mistake. The Mute key acts flaky: it always turns sound off, but often it won't turn it back on (I have to do it with software).

I'll play with these 6 keys and see if doing so puts it into the strange mode, and gets it back out again.

I have the same problem : Shift + t,b,y,b,n and / (i can't type question mark) , but i dont have any extra buttons like mute pause or play... just a regular standard keyboard and since while i had this problem once before... it just fixed by itself first time but i want to know what is the solution :/
Please someone share an experience and help me thanks.

6 years later... you are still helping someone Solinari. I just signed up to thank you... I spent weeks! trying to fix this!!.. and what do you know... a simple press on a few multimedia keys on my keyboard (as you suggested) fix it!!... I was seriously thinking of returning this keyboard as defective... lol!..

Thanks for the help.
