I noticed that some of my keys in my Asus K55N doesn't work anymore, They are d,f,j,k,l and ; keys. I tried reseating the keyboard ribbon cable and those keys doesn't work, I brought an keyboard for my laptop in ebay and those keys doesn't work. I even tried going to the bios and try setting the password using those keys and it definitely doesn't work. I tried plugging an usb keyboard and that works.

Anybody have a good solution or I hate to say that the mobo is bad? Thanks.
