Question about Sony VAIO VGN-FJ270/B Notebook
Usually this is due to a hardware problem with the keyboard. 98% of the time by replacing the keyboard you'll fix the problem.
You could also try reinserting the data cable from the keyboard to the motherboard.
It can sometimes get a tiny tiny bit loose and cause problems like this.
Be VERY careful when you remove the plastic tab that holds the keyboard data cable in place. They are EXTREMELY easy to damage.
I know I've messed up plenty myself
Best of luck!
