NEW ASUS F2 F3 Series Keyboard Teclado Spanish 28 PINS

ASUS F2 F3 Series Laptop

Attention (Item story): Asus F2 F3 series have 2 kinds of laptop keyboard, they are almost the same except the cable which connect the keyboard to the mainboard, one has a 28 pins on it, and the other one has a 24 pins. In the very beginning, I thought 28 pins cable is for F3, 24 pins cable is for F2. A little later, I  found this is wrong, then I  thought 24 pins is for F3, and 28 pins is for F3.  But it's wrong too because some costomer say his F3 laptop has  a 28 pins cable. I'm really confused.
