Hey!
I've just done this two days ago to update my M1450G from 512 to 2GB.
Look on the edges of the black thing on your keyboard, round the keys. You should see some little clips which you need to get a flathead scredriver and just push them under the keyboard. There is one by the ESC key, 2 more on the top, one next to PgUp and the same on the other side. None on the bottom.
When all are released you need to remove the keyboard and you should see a metal sheet which i attached via screw. Remove the screw and then the sheet. Your RAM bay awaits.
Hope this helps if you need photos just email me @
richardfennah@gmail.com.

BTW. If anyone has any ideas as why my RAM might not be working properly please can you reply? It seems to work sometimes and not others. I needed it primerally to run Microsoft Flight Simulator 2004 with some good addons. Any help would be appreciated. I am now using 2GB between 2 1GB sticks of:
