guide was developed to instruct readers on the proper procedures for installing
SODIMM memory module into a laptop computer. It includes step-by-step instructions
for the physical installation of a memory module into those laptop systems that
have an access panel to the memory modules. Not all laptops have this type of
access. If yours does not, then it will probably require installation from an

1: Get out the tools you'll need.

2: Ground yourself.
electricity can damage your module and other computer parts. You need to ground
yourself to avoid "shocking" your computer. If you have wrist straps
designed for this purpose, you should wear them. If you don't have wrist straps,
here is the easiest way to ground yourself:
off the computer, monitor, and all accessories (printer, speakers, etc.)

touch an unpainted metal part of your computer case.

again before touching any of the internal parts of your computer.
3: Open your computer case.
laptop case is a little different, so consult your manual to find out where your
SODIMM slots are located and how to open that part of your laptop case. Some of
the most popular places for SODIMM slots are:
a back access panel
the panel used for access to the memory modules. This is generally located on
the bottom of the laptop computer. Refer to your laptop instruction manuals for
locating the panel.
any screws that the panel in place and place somewhere safe to prevent losing
the SODIMM slots and banks.

most SODIMMs are installed individually, some SODIMMs must be installed in matched
pairs known as "banks." The memory banks on your motherboard should
be clearly labeled.
5: Remove the memory you are replacing (if necessary).
you have an open SODIMM slot, skip this step and go on to Step 6. If all of your
SODIMM slots are full, you will need to remove one or more of your old modules
before you can install the new memory.

keys in the SODIMM slot on your motherboard. (If the notches don't line up right
away, flip your module around and try it the other way. It doesn't matter which
side of your module has the black chips or the stickers on it. The important thing
is to line up the notches.)

the module into the slot at a 45-degree angle.

lock into the module into place.
7: Test it.
the memory has been installed into the computer, the physical process is complete.
When the computer is powered back up, it may be necessary to go into the computer
BIOS to let the system properly detect the new RAM that has been installed in
the computer. Please refer to the user manual for the computer system for any
you close your case, turn your computer back on. You should see the new amount
of memory displayed on your startup screens or in the properties for "My
Computer" (if you use a Windows operating system). If everything works correctly,
skip to Step 9. If not, go to Step 8.

the module and replacing it to make sure it is seated properly in the slot.

cables inside your computer while you were installing your module? A loose hard

the cables are firmly in their sockets.
