How computers work – laptop assembly

Introduction – how manufacturers assemble a laptop – how computers work

Let’s introduce you first of all to how to assemble a laptop and explain how laptop computers work.  Before you can begin to to troubleshoot hardware problems with any laptop it’s important that you understand how they are actually assembled by the different manufacturers.  As we will see next, laptop assembly follows a system and a pattern.
Have a look at this picture of an exploded laptop below:

Despite all of the numbers depicting the different parts, you can actually envisage the laptop in simple separate parts and to use a useful analogy for the moment try and imagine a cheeseburger.

Using an analogy to show how to assemble a laptop – the cheeseburger

Cheeseburger for analogy

These are the parts of the cheeseburger.  we have:

  • the outer bun
  • the gerkins or onions layer
  • top cheese layer
  • the top burger
  • a layer of cheese again
  • another burger
  • the bottom part of the bun

This is not too dissimilar a description to that of most laptops.

To describe how computers work, in other words how most laptop computers are built, they have:

    • laptop-screenthe top part of the case that contains the screen (the top bun)


  • the keyboard bezel or hinge plate cover (HPC) (the gherkins and onions)Hinge-Plate-Cover or keyboard bezel
  • the keyboard (the top cheese)laptop keyboard
  • the top part of the lower case (the top burger)top-part-of-laptop-lower-case
  • the motherboard (the next cheese layer)laptop motherboard
  • the components such as the hard drive etc (the bottom burger)laptop components
  • the bottom part of the lower case


This analogy describes the majority of laptops and how they are assembled.  Bear in mind that this is a rule of thumb as manufacturers tend to have their own versions but whenever you approach a laptop you have never seen before you should feel confident that you will recognize the different parts as shown above.

Taking a laptop apart – the disassembly / teardown

In order to build your confidence in how laptops are assembled we are next going to look at something called a Laptop ‘Teardown’ which is the name given to the  Laptop disassembly process.  A Laptop ‘Teardown’ essentially describes a process where every part of a laptop is stripped down and taken away from every other part and you will end up with each part laid out on your table or workbench in front of you.

Before you proceed it is recommended that you obtain both a practice laptop that you can carry out your teardown on and also an appropriate set of tools.  This way you will be able to get some hands on practice at how to disassemble a laptop.  Not to worry if you can’t get your hands on one right now but you can always come back at a later time to this tutorial.


The majority of laptops can be taken apart in 8 easy steps.  Let’s look at them now…

Laptops evolve all of the time and there are so many variations that if you plan to repair laptops for a living you really need to understand how they work. You need to be able to apply your knowledge to any type of laptop or netbook without constantly referring to tear down guides.

This is what Tekmoz gives you – a clear understanding of how laptops are put together, how they work and how you can repair or replace parts to fix them.

Tekmoz will give you the skills to work as a laptop repair technician – perhaps start your own business, add to your existing skill-set, save money by repairing your own laptop or even just learn a great useful new skill.

It does NOT cover chip or motherboard repair and there is a good reason for this.

As the author of this work I have worked in the industry for 20 years and I make a good living from repairing laptops and computers. However, like most computer technicians I am not an electronics engineer – if I have chip issues or motherboard issues I have a specialist take care of that for me simply because I can spend more time replacing parts such as a keyboard or laptop screen repair – these are quick and easy jobs & make you great money.
What I will teach you is how to do the job of a laptop repair technician so you can apply your skills in a smart & efficient manner when it comes to fixing a laptop.
Lets start our laptop repair training

For laptop repair training…you will need a laptop to practice on

In order to get the most from this laptop repair training you should really obtain a laptop to practise on.

It doesn’t matter if the one you pick actually works or not.

(Btw, as a musician, I couldn’t help myself but share this post from Victor Bailey featuring 6 best cheap laptops for music production (under $500): link.)

Where can I get a laptop to practice repairing?

The best place to pick up a cheap laptop to practice on  is Ebay, search for ‘broken Laptops’.  The last time we checked there were over 10,000 laptops you could pick up to practice on. You can check yourself before moving on with the training.

We recommend that you do. Done that? Good.  Imagine being able to buy, repair and sell those laptops!  You can strip them down and sell the parts of simply fix and resell them.

Tools you will need during the training

For the majority of laptop repair jobs we have found that you will mostly only use a selection of precision screwdrivers and occasionally a Laptop Repair Toolssoldering iron.  We will cover the tools you require on the next page.  If you have these already, great, if not then again Ebay or Amazon are a great source for these.


Workbench, desk or kitchen table

Try to create a place to work where you have plenty of space.  Taking a laptop apart can produce a lot of parts that may need to be spread around to help keep a track on where they came from or to help you determine a fault.  Remember that laptop parts can sharp and can scratch a table so make sure whereverscratched table you work you bear this in mind.  We prefer to work on a piece of foam or cork board, rolled up foam is great if you need to take a laptop apart when working from a clients home.

You will also need

  • Plastic screw box Plastic Screw Box
