Query: Didn't work for me

Bought it to replace my Inspiron 9200's keyboard but there was no use to it. Although the size was a perfect fit the ribbon cable on the keyboard had a connector which wasn't needed (as someone said, on the native keyboard the ribbon cable goes straight down, directly to the connector slot) and even after carefully removing it without damaging the actual thing and making it go in place (which by the way had to be done by twisting the cable around) many keys wouldn't work.
