Operating Systems

First of all it’s a good idea to identify which operating system (commonly known as OS) you want to go with, you may already have a preference, however, if you’re unsure take a look below to see some advantages and disadvantages of each of the platforms available.

Microsoft Windows

- The worlds most popular OS with the largest range of supported software
- A large range of choices in comparison to Chrome and Mac.
- Specially designed features for touchscreens and voice controls.

Apple macOS

- Sleek, stylish design - some would argue Mac design outclasses Windows but there are now plenty of premium 
- Allows functionality with iPhone, Siri, iCloud, Apple Watch, Apple Pay etc.
- Doesn’t offer the largest variety of software choices
- Some newer models lack ports and you need to pay for additional accessories

Google Chrome OS 

- Inexpensive
- Sleek and lightweight
- Limited to web apps created by Chrome
- Good battery life
- Portable
- Great for school or child’s first laptop 

Know Your External Specs


When you’re thinking about screen display and resolution, generally the more pixels you have, the more content you can fit on the screen and the more detailed images will look.

  • A good option to choose is Full HD display which is 1920x1080 (commonly known as 1080P)
  • Some more expensive laptops have screens which are 3840-2160 (4K) and 2560x1440 (1440P).
  • Choose your resolution depending on your needs, however, keep in mind that you will receive better quality of all your favourite web pages, you’ll be able to multitask better and enhance your movie watching experience with a higher pixel resolution.


The internal durability of a laptop tends to be the main priority on the average laptop-shoppers mind, but it’s also important to consider the durability of the external parts of a laptop – especially if you’ll frequently be on the go, using the laptop for long periods of time, or if the laptop will be used by a younger person (eg. a primary school student).

  • Some laptops come designed to prevent wear and tear with elements such as water-resistant keyboards or rugged designs. Look out for these features if you think your laptop may be prone to being dropped or having food and drink spilt on it.
  • If you’ll be using your laptop for strenuous work or running multiple programmes, make sure the laptop has a suitable cooling fan. There’s nothing worse than having your laptop overheat on you and losing precious work or data.
  • Think about purchasing some additional accessories to protect your new laptop, such as a case or carry bag, keyboard cover and/or screen protector.

Screen Size

Choosing the right sized laptop is also important and ultimately comes down how portable you need your laptop to be. Generally, laptops are categorized by their display sizes, see below:

11-12 inches

An 11-12 inch laptop is the lightest and thinnest system. This size typically weighs 1-1.5 kgs. As this is the smallest size, the screen and keyboard may be too confined for some users.

13-14 inches

This size provides great portability and usability and usually weigh 2kgs. This size will fit comfortably on your lap and still gives generously sized keyboards and screens. A laptop under 2.5kgs would be ideal, however extremely lightweight systems are available with these screen sizes. This is an ideal sized screen for a student or business worker.

15 inches

15” is the most popular laptop size, tending to weigh around 3kgs, and are great all-rounder laptops perfect for home use. Generally this size is inexpensive and is ideal for work purposes or if you don’t require to carry your laptop around with you, however is less portable than the smaller 11-13 inch. A lot of 15 inch models include DVD drives.

17-18 inches

If you’re wanting to play high end games or do workstation level productivity you may want to consider a 17-18 inch model, as long as your needs include leaving your laptop on your desk all day every day as these tend to be quite heavy. Laptops this size can pack in high speed quad core CPUs, graphics chips and multiple storage drives.

When shopping for a laptop, it’s a good idea to – if allowed - physically handle the display models to get an idea of how heavy the laptop will be. Another idea is to bring a bag that you will be using to carry the laptop in with you to see if the screen size fits the bags measurements. Alternatively, measure your bag inside and out and bring these measurements with you. Keep in mind other items you may be carrying with you like chargers, headphones, personal items etc.

Shop by Screensize


2-in-1 Hybrids

Recently a number of hybrid “2-in-1” laptops have come onto the market. These laptops bring the best of both worlds, doubling as both a laptop and a tablet by using bendable and rotatable screens. If you’re regularly going to use your laptop in slate mode or want flexibility to use your laptop as a standalone tablet you may want to consider these versatile designs. These models offer touch-screen capabilities.

Intel's Ultrabook™ standards have not been updated publicly for several years, but at the time of writing this, a laptop qualifies as an "Ultrabook" if it meets the following physical specifications.

  • (20 mm) for laptops with smaller displays (less than 14")
  • (23 mm) for laptops with larger displays (14" or more)
  • Battery Life: At least 6 hours of HD video playback or 9 hours of Windows OS idle time
  • How long to wake up from hibernation: 3 seconds or less

Keyboard & Mouse

The keyboard and mouse functions are an integral part of how you use your laptop. It’s important to make sure these elements are both comfortable and easy to use.

  • Make sure the keyboard is large enough for your hands to easily reach and press all keys, and that the keys aren’t sticking or feel too loose.
  • The touchpad mouse should be satisfying to click, easy to grasp, pinch, scroll and click with, and have the ability to adjust touchpad sensitivity to suit your preferences.
  • Alternatively, if you prefer to use an external mouse or keyboard, make sure there’s an ability to use wireless accessories or plug in with a USB port.
  • Backlit keyboards are a great option for those using their laptop in low-lit areas such as the bedroom, at night, or gaming with the lights off.
  • Smaller laptops (<15 inch) don’t include the NUMPAD keys and this can be an issue for some users.


Laptop ports allow for users to plug in, charge, and use multiple different devices on your laptop. It’s a good idea to consider what you’ll be using your laptop for and what type of connections the cables are on your other devices. Below is a list of ports, what cables/products these would use, and what context they’d be used for.

Whilst almost all laptops have an audio jack to plug in headphones or earphones, some users prefer to watch video, listen to music or work on their laptop without these. Regardless, if audio is important to you - consider the following:

  • Does the laptop have a speaker system and what is the speaker quality like?
  • Is the sound clear and distinct enough to be heard on multiple volume levels
  • Does the laptop allow for speakers and/or headphones?
  • Will quality of sound impact your experience (eg. Are you a music or video producer, do you frequently watch content on your laptop, etc.)
  • Is there the option to plug in external speaker systems in a USB port?

Know Your Internal Specs

It may be daunting at first looking at spec sheets, but it’s important to make sure you’re getting the one that best fits your needs. As mentioned above, you need to know what you plan to do with your laptop as this will determine which components you need to look out for. For example, if you’re wanting to do intensive 3D gaming more components may need to be included. See below for common components you should be aware of.


CPU is the abbreviation for Central Processing Unit. Sometimes referred to simply as the central processor, but more commonly called processor, the CPU is the brains of the computer where most calculations take place

  • Some less expensive laptop models have Intel Celeron or Intel Pentium CPUs, which offer long battery life, however, tend to struggle with high productivity and media tasks. Web surfing and general daily tasks can easily be done. 
  • If high-quality performance is vital to your laptop needs, it would be ideal to go for Intel M or better for thin systems or a Core i3/i5 CPU/AMD A or Ryzen 3/5 series for mainstream systems.
  • Video editor and graphic designers should look to the Core i7, i9 or Ryzen 7 series.
  • If you’re a power user or frequent gamer a Core i7 would be ideal.


RAM (pronounced ramm) is an acronym for random access memory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in computers and other devices

  • In terms of RAM, (the computer memory), you shouldn’t settle for anything less than 2GB, as even the cheapest of laptops have this amount.
  • If you need to be multitasking and using high-end applications, a system with 6-8GB would be appropriate.
  • Power users and gamers should be looking at 16GB of RAM minimum.

Solid State Drives (SSDs)

  • SSDs – or Solid State Srives - help to improve performance and are arguably more important than your laptop CPU. They come with less capacity than traditional hard drives: usually between 128-256GB.
  • If you can afford it and don't need a ton of internal storage, get a laptop with a solid state drive (SSD) rather than a hard drive, because you'll see at least three times the speed and a much faster laptop overall.
  • With an SSD you will receive faster boot times, faster resume times as well as faster application open times.
  • Another advantage of SSDs is that there is less chance of failure due to the fact that they do not having moving parts, as mechanical drives do.

Battery Life

Battery life is also something to be aware of. If you're buying a large, bulky notebook that will only be used near a power outlet with the charger readily available, you don't need to worry about battery life. However, if you’ll be using your laptop for long periods of time (eg: in a typical 8 hour school day) you’ll be wanting a laptop that is able to last this capacity. Battery life will vary between models and depend on screen brightness as well as the tasks you perform on your laptop, so it’s good to think about how you will be using your laptop when considering battery life.

  • To ensure you can move your laptop around with you, if you’re looking at a 15-inch laptop, 4 hours of endurance would be ideal.
  • If you’re needing to be fairly mobile with your laptop you should look for laptops with around 7 hours of endurance.
  • Some laptops offer extended batteries if given the choice this would be a good idea, however, some do not feature upgradeable batteries. Gamers, travellers or consumers shopping for laptops for school students may want to consider this option.
