I have a CN6555, if the picture you put is the real laptop, my laptops it's almost the same, so one memory bank should be easily accessed because it's in the middle from the down side (where you access the batery pack); the second one, :(, well, unfourntanly it's a little bit complicated, because you must disassamble the laptop, under the keyboard it's the second memory bank, under a metalic plate. Just put out the plastic cover near to the LCD, with a tiny screwdriver remove the keyboard and the metalic cover under the keyboard and you will see the memory bank.
