SOS! Keyboard disaster...

[manfer87]

My Keyboard isn't working properly half of this was typed on the on screen keyboard!

Keys not working include 

p, bksp, left side shift, numbers 135789, 

the ones that don't work make the power light blink

i have tried - system restore, un install keyboard, taking keys off to check underneath, 

suggestions more than welcomed.....

Hi manfer,
if you have tried a system recovery & the problem is still present then I would seem to indicate at a hardware problem.
Maybe time to contact Sony support to arrange a repair.
