I have completed the Bluetooth addition as well as the network card upgrade following Groovy’s guide. However, when I put back all the parts together and powered on the computer, nothing comes on. I am pretty sure I have followed the procedure really closely, and the only things that could go wrong are the interface ribbons (keyboard and daughterboard). How much should they go into the socket? No matter how hard I push, the ribbons won’t go in completely. Anyone of you has experience dealing with this? Thanks for your advice as always.

The keyboard plug is really a clamp. The top of the plug swings like one of those revolving bookcases you see in movies. Pull up the black part on the side closest to the DVD drive. It should swing so you can easily place the keyboard ribbon in the now enlarged opening on the left side. Push back to clamp into place.

You need to be extremely careful when you’re putting the keyboard interface cable back and the interface cable for the touchpad/power. The touchpad one which is connected to the palm rest is very delicate and has strips of metal on it. If you try to jam it back in it’s possible for the strips to get offset or to break off…so be very careful!

The keyboard one isn’t as delicate and doesn’t require any force. Simply slide it in until it no longer gives and the push the brown lever down to lock it. That’s it.

Thanks for your advice! I got the TR working again
