Could you tell me how did you disconnected the keyboard from the motherboard?
It's actually quite easy as I successfully swapped out a faulty keyboard for a replacement that PCS sent to me.
All you need to do is remove the plastic strip between the keyboard and speakers (it's not screwed down) by carefully prising up the left & right edges. Once removed you will see the screws in the lugs holding down the keyboard (I think there are about 5?!) so grab a small cross-head screw driver and unscrew all screws and put them somewhere for safe keeping. Now, carefully lift up the two middle lugs and gently pull the keyboard towards the screen, and you should see two ribbon cables under the screen, both held in place by two locking clips. Prise away these clips very carefully to release the ribbon cables and the keyboard will come free.
Hope this makes sense?
Disclaimer: I take no responsibility if you damage your computer in the process of removing the keyboard so only proceed if you feel comfortable in doing so.
