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 service door. 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.
NOTE: Before adding or replacing a memory module, make sure the computer has the most recent
BIOS version, and update the BIOS if needed. See Updating the BIOS on page 59.
CAUTION: Failure to update the computer to the latest BIOS prior to installing or replacing a
memory module may result in various system problems.
WARNING! To reduce the risk of electric shock and damage to the equipment, unplug the power
cord and remove all batteries before installing a memory module.
CAUTION: Electrostatic discharge (ESD) can damage electronic components. Before beginning any
procedure, ensure that you are discharged of static electricity by touching a grounded metal object.
NOTE: If you are adding or replacing the memory module in your computer with a single memory
module, insert the memory module into the slot closest to the system board.
NOTE: To use a dual-channel configuration with a second memory module, be sure that both
memory modules are identical.
