Keyboard Key missing

I have a notbook and USB connected Keyboard. It used to work ok but suddently, I have missed 7 keys. I cannot type -['0p;/(the right hand side of two rows). I have tried to uninstall the keyboard and re instal it again, it didn't help me solve this problem.
Please help me. Thanks

Does your regular KB work? Have you tried another keyboard? Try turning the KB upside down and blowing out the dust. Unlikely anything major would affect only a few keys.....

 

On my notebook, that is approximately where the "numeric pad" keys are. I don't know if hitting the function key (FN) and turing on the keypad on your laptop keyboard by accident could have causing the same keys on the USB Keyboard to blank out?

Is there a light/indicator on your laptop saying that the keypad is activiated? With mine I hit FN and another button that has a picture of a numeric keypad on it. THen I hit FN and the same button again to turn it off.
