Im sorry I dont know about your specific laptop but most that have memory under the Keyboard have clips at the edges to remove them.
If you check beside the BACKSPACE and TAB keys there is usually a small black tab slider that if you use a Flat head Screwdriver can be pushed aside to let you lift the keyboard.
They can usually be spotted easily enough at the edge of the keys.
Hope that helps!
