Hi there
I have a little silly question to be answered asap.

I'm using Lenovo Z560 with Logitech X7 keyboard and mouse set. I don't know how i managed to do it but i can't type letters on my USB keyboard now. It doesn't have a FN button so the only solution i could get on the internet -which was "FN + NumLock"- is not working. I tried my keyboard on another computer and also tried another keyboard on my computer and it's the keyboard..

So far i've tried fn+ScrLock - fn+NumLock - Sticky Keys - spamming NumLock on OSK and few others. None solved my problem. I need to fix this asap. Any help appreciated. Thanks.
