Chapter 4
Complete Disassembly /Taking the Laptop Apart
I will explain here how to disassemble any laptop, and not just focus on one specific model. I
will teach you this way because there is a general rhythm to the placement of the screws and different
types used.
With all laptops, you will start the disassembling by flipping the laptop over to its bottom side.
Use a foam pad if available so you do not scratch the lid/cover.
Removing the battery is the first thing you will do.
Now you will start with removing all the screws. You will start at the rear of the laptop where
most batteries are located (most, not all…). Start right in the battery bay and remove all the screws
inside it. Here you will find smaller screws usually 2 to 8 of them, and typically they are silver or
black in color – usually being silver. Also in some battery bays you will have keyboard securing
screws, these will be removed also at this time. If you like, you can save the screws in one big pile,
or you can separate them by size. Laptops do not use a million different sized screw’s, rather, they
will use a set of sizes and stick with those size differences throughout the laptop, usually having 2 to 5
different lengths or thicknesses per laptop model. If your specific battery is not located at the rear of
the laptop, you still will remove it, though it will probably not have any screws in its empty bay (if
there are any, remove all of them).
Next you will remove all of the screws at the rear corners of the laptop. Typically they will use 1
to 3 on each side. These will be the longest screws used on your laptop, the far corner screws will be
the longest – sometimes being thicker too, then, the ones further inward will usually be a little shorter.
Still at the rear or the laptops bottom side, you will remove any screws in the center/rear and you
will usually find 2 or so screws there… While still at the rear side, flip the laptop up a little and look
at the rear of the laptop. Look for any screws at the Hinge Cap area, as some laptops will use 1 or 2
per hinge cap to secure the cap to the base, remove them. While still at the back side of the laptop,
look for any securing riser screws. Riser screws are found in areas like the VGA Serial Port or a
Printer Port, look on each side of that port, there will sometimes be riser screws. Remove them using
needle nosed pliers. Other extension ports on the rear and sides of the laptop will have riser screws
that need removing and some will be removed with a micro sized flat head screwdriver. Some of
these riser screws can be left in and still allow for complete removal of all parts, but if you are not
sure, you should remove them.
You can now remove any case covers that exist on the laptop in front of you. The photo on the
previous page shows 1 main cover that will cover all accessible components, some laptops use just
one, and some will separate them and use 2 to 4 separate covers. Remove all of them regardless.
Note that some laptops will use extra long or extra short screws to secure the covers and if you think
you will have trouble remembering the placement of these upon reassembling, then place the screws
for each separate cover inside that cover and set the covers aside with their screws on them. After
removing these covers, you will remove the components inside their bays. These will include the
