1.	Solve : Key touch pad does not work when push it for using as ENTER?
Answer» My acer laptop's touch KEY pad has some problem. The cursor is ok and it moves normally but when I push on the pad as ENTER option, it does not. In that case I have to PRESS the left button of the pad mouse EVERY time. It is so BORING and taking time.
