Apologies if I have put this in the wrong section.

My sony vaio laptop (model no SVE1511K1ESI) last night occured a problem. Out of the blue a group of keys on my keyboard stopped working, as far as I know it is Q, E, T, I, O, G, down, up and the largest enter key, however there could be more I haven't noticed yet.

I tried a few different 'solutions' suggested online including searching for a driver update and the shut down and take the battery out then start again. Neither had any success.

I'd be grateful if any help could be given. Thanks.
