Adding or replacing memory modules (select models only)
Adding memory can help improve your computer's performance. Your computer is like your physical
work area. The hard drive is the filing cabinet where you store your work and the memory is the desk
where you work. When your memory isn't big enough to hold all your work easily, like a desk
overflowing with work, your productivity slows down. A great solution to improve performance is to
expand the amount of memory you have in your computer.
The computer may have one or two memory module slots depending on the model. The memory
module slots are located on the bottom of the computer under the service door. The memory capacity
