This
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
authorized technician.
For
additional information about installing computer memory into your computer system,
it is recommended that you read any user manuals that came with your computer
for specific procedures that may be required. For more information for purchasing
memory upgrades for a computer, please refer to the Before You Buy Memory upgrades
article.
Step
1: Get out the tools you'll need.
Non-magnetic
screwdriver (for opening your case)
Your
computer manual
Step
2: Ground yourself.
Static
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:
Turn
off the computer, monitor, and all accessories (printer, speakers, etc.)
Leave
the computer power cord plugged in. (It's OK to unplug your accessories if you
like.)
Briefly
touch an unpainted metal part of your computer case.
Plant
your feet and don't walk around. If you do need to walk around, ground yourself
again before touching any of the internal parts of your computer.
Step
3: Open your computer case.
Every
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:
Under
the keyboard
Behind
a back access panel
Locate
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.
Remove
any screws that the panel in place and place somewhere safe to prevent losing
it.
Step
4: Find
the SODIMM slots and banks.
Remove
the panel from the laptop and set aside.
SODIMMs
fit into slots that look like this. Some of your slots may be already filled with
modules.
SoDIMM
Slot This notebook has two slots. Some notebooks may have only one slot.
While
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.
Step
5: Remove the memory you are replacing (if necessary).
If
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.
Press
down on the retaining clips on either side of the module.
Remove
the module from the slot.
If replacing
or upgrading an existing memory module, remove the memory modules by undoing and
module clamps and gently lifting the edge of the module to a 45-degree angle and
then pulling the module out of the slot.
Step
6: Install
your new module(s).
Take
your module out of its anti-static bag and hold it by the edges.
If
you have more than one open slot, fill the lowest numbered slot first.
Line
up the notches in the row of metal pins at the bottom of your module with the
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.)
Align
the notch of the memory module with that of the memory slot and gently insert
the module into the slot at a 45-degree angle.
Once
all the pins are in the slot, gently rotate the module down flat until the clamps
lock into the module into place.
Step
7: Test it.
Once
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
additional information.
Before
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.
Step
8: Troubleshooting
If
you have trouble with your new RAM, check these things first.
Check
the power cords. Is everything plugged in properly?
Check
the module. Did both side clips snap to hold the module firmly in place? Try removing
the module and replacing it to make sure it is seated properly in the slot.
Check
the wires and cables inside your computer. Did you accidentally bump one of the
cables inside your computer while you were installing your module? A loose hard
drive cable can prevent your computer from booting up properly. Make sure all
the cables are firmly in their sockets.
Step
9: Close
your case.
Replace
the memory access panel.
Replace
any screws or fasteners that hold the panel in place.
