Laptop buying guide

Laptops cover everything from light machines for browsing and writing to heavy workstations for video editing and gaming. The best one for you depends on where you use it, what you run on it and how long you want it to last. This guide explains the specifications that make the biggest difference day to day and the questions to ask before you buy.

Start with how you will use it

• Study, browsing and office work: prioritise weight, battery life, keyboard and screen quality over raw performance.
• Creative work (photos, video, music): look at the processor, memory, storage speed and an accurate screen.
• Gaming: a dedicated graphics card and a high-refresh screen matter most; expect more weight and shorter battery life.
• Travel: weight, size, battery life and charging over USB-C are the priorities.

It helps to decide which of these describes you best before looking at specification sheets.

Operating system

Windows, macOS and ChromeOS each have strengths. The key questions are which software you need, which devices you already use and how long the manufacturer promises updates. ChromeOS devices have a published automatic update expiry date, which is worth checking before you buy. If you rely on a particular app, check that it runs on the system you choose.

The specs that matter

Processor (CPU)

The processor determines how quickly the laptop handles demanding tasks. Model numbers indicate generation and tier, but laptop processors vary widely in power limits, so two machines with the same chip can perform differently depending on cooling. For heavy work, independent benchmarks of the specific laptop are more useful than the chip name alone.

Memory (RAM)

RAM lets you keep more apps and browser tabs open at once. Many laptops have memory soldered to the board, so it cannot be upgraded later — buy enough at the start. For general use, more memory makes multitasking smoother; for creative work and development, aim higher.

Storage

Solid-state drives (SSDs) are standard. Capacity matters more than people expect, particularly with large photo libraries, games or offline files. Check whether the drive can be replaced or whether there is a second slot.

Graphics

Integrated graphics handle everyday use, video playback and light editing. A dedicated graphics card is needed for modern games and some creative software, at the cost of weight, heat and battery life.

Screen

Size, resolution, brightness and panel type all matter. OLED panels offer deep blacks and strong contrast; IPS panels are common and consistent. Glossy screens can look vivid but reflect light; matte screens cut glare. A higher refresh rate makes scrolling and games feel smoother. Brightness is quoted in nits — useful if you work near windows or outdoors.

Battery and charging

Manufacturer battery figures are measured under specific, light conditions; real-world use is often shorter. Compare figures within the same brand, and check whether the laptop charges over USB-C, which lets you share chargers with other devices.

Build, keyboard and ports

Weight, keyboard comfort and the trackpad affect daily use more than many specifications. Count the ports you need — USB-A for older accessories, USB-C or Thunderbolt for displays and docks, HDMI for presentations, and a headphone jack if you use wired headphones. A webcam with a privacy shutter and a fingerprint reader or face login can be useful extras.

Key specs explained

Questions to ask before you buy

1. What will I mostly use it for, and where?
2. Does my essential software run on this operating system?
3. Is the memory upgradeable, and if not, is there enough of it?
4. How long will the manufacturer provide security and system updates?
5. Does it have the ports I need, and does it charge over USB-C?
6. Is the cheapest offer the exact same configuration — processor, memory, storage and keyboard layout?

Frequently asked questions

How much RAM do I need?

For browsing and office work, a moderate amount is enough; for creative work, development or heavy multitasking, more is better. Because many laptops cannot be upgraded later, it is safer to buy a little more than you need today.

Is a touchscreen worth it?

It depends on how you work. Touchscreens and 2-in-1 designs suit drawing, note-taking and presentations, but they can add weight and cost and may reduce battery life.

Why do two laptops with the same processor perform differently?

Laptop makers set different power limits and cooling designs. A thicker laptop with better cooling can sustain higher performance than a thin one with the same chip.

Should I check the keyboard layout?

Yes. Laptops sold in the UK normally have a UK layout, but imported or marketplace listings may not. Check the listing if this matters to you.

Prices & links

HotWhatHow compares live prices from retailers as they are connected to the site. When offers are available, we rank them by the total landed price — the item price plus standard delivery — and show when each price was last checked. Some retailer links are affiliate links; we may earn a commission, which never changes which offer we label as the cheapest.
