Hi,
I have HP laptop. today suddenly 2 keys on my laptop punch wrong letters.
Like if I want @ I have to press keys Shift + key just left to enter key and vice versa for " I have to press shift + 2.
rest of the keys are working properly. And I have tried this option in both conditions of Num Lock Off & On
I had this problem with notebook HP COMPAQ PRESARIO CQ71401SA
after trying all different things I solved my problem removing keyboard from computer and cleaned the connection with electric cleaner gave it a rub with toothbrush and then used eye dropper to suck and blow it has worked since
