Adding or replacing memory modules
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 has two memory module slots. The memory module slots are located on the bottom of
the computer under the hard drive cover. The memory capacity of the computer can be upgraded by
adding a memory module or replacing the existing memory module in one of the memory module
slots.

cord and remove all batteries before installing a memory module.

Electrostatic discharge (ESD) can damage electronic components. Before beginning

memory modules are identical.
