I just replaced the screen in my Portege R100 laptop. I used the instructions from Screentekinc - everything was much as described there. There are four screws under rubber pads at the top of the R100 screen, and six under small square pads around the bottom and the sides. All of these can be removed with a sharp knife - I used a Stanley knife. You'll need a very small Phillips screwdriver to unscrew the screws. (Or you can just use the Stanley knife. But you'll probably damage the screws and your blade. Yeah, that's what I did.)
After that I unclicked the plastic surround to my screen - it requires a bit of a pull and is best started from the bottom left, once you've got the first bit the rest comes easily. Then you are face to face with the screen. The rest is pretty much as in the tutorial. You pull out the data plug (having first removed any sticky tape holding it down), and the inverter plug which provides the power. (You did remove the battery, right?) To remove the inverter plug it's much easier to unscrew the inverter first (it's the long thin circuitry on the right hand side of the screen, held in place by a single screw). Then you have to pull hard and use your fingernails to get the inverter plug out.
Once that is all done you just replace your screen, plug the new screen back into the inverter and the data connection, sticky tape it up, slot your plastic surround back in and screw everything back in place. Pah! Child's play.
