The 204-pin SODIMM module is keyed to only fit in one way, just be sure to insert the memory into the socket so that most of those gold pins are no longer visible. Two springs put tension the memory module as you push down on it so there will be a small amount of resistance. Push it down all the way until the two clips click into place. There is one on either side of the memory module PCB which lock the RAM in place.

Swap out or upgrade the hidden memory module as needed, then replace the aluminum panel cover and tape it back in the locked position.

The keyboard should slide back into place bottom first so the locking tabs engage with the notebook chassis. Press the keyboard down lightly to make sure it's fully seated and the adhesive squares are in contact with both aluminum surfaces. The next step is to replace the chrome plated plastic strip which locks the keyboard in. That plastic strip needs to be inserted in its groove so each of the tabs engage.

In the photo below is a closer look at the tabs on the strip and slots in the chassis the tabs engage with.

Install the chrome plated plastic strip and slide it a few millimetres to the left so all the tabs engage. The right corner of the chrome plated plastic strip will be sticking out still, as detailed in the photo below.

Push the right-hand end of the strip in towards the left a little, to get the little nub of plastic pointed down, the tab should then pop into place in the notebook chassis. When it's flush to the black plastic frame, it's installed.

WARNING - If that little bit of plastic is not installed properly and is not flush to the rest of the notebook, it may crack the LCD display when the screen is closed!

That's it! The only other step is to power up the notebook and ensure the full memory capacity is reported in the BIOS. Thanks to Crucial Memory for help with this DIY Guide.
