keyboard lights up but doesn't work

[siege44]

My hard drive crashed so I took my laptop apart just for fun and then found another hard drive to use. I have it all back together, installed ubuntu and it's running fine, the only problem is the keyboard doesn't work. the light in the caps lock and wireless key light up, but the buttons don't do anything. One thing I don't have is screws holding the keyboard to the body through the motherboard. I put them in a bag somewhere but can't find the freaking things. I doubt it would make a difference, but maybe it's worth mentioning. Any suggestions would be appreciated.

Hi, did you push the mechanical lock for the keyboard ribbon?
