Memory
How many ram slot are currently used by the system ?
There are two 2gb ram in two slot ?
According to the videos that I have seen on the internet, it has 2 slots. However, they are difficult to get at. You will have to remove 18 screws at the bottom of the laptop, pry open the keyboard area, take out the logic board to get access to the memory slots which is on the underneath side of the logic board.
