Laptop buying guide
A laptop is a bundle of screen, keyboard, battery, ports, software and support as well as a processor. Start with the work, apps and places where it will be used. That makes it easier to choose a machine that is comfortable at a desk, portable on a train and supported for as long as you need it.
Start with your needs
What will you use it for?
Use these starting points to build a shortlist, then check the trade-offs against the exact product and its reviews.
| Your priority | Look for | The trade-off |
|---|---|---|
| Office and study | Keyboard, webcam, quiet operation, battery and ports | A very thin machine may offer fewer upgrade or repair options. |
| Creative work | App requirements, display, storage, memory and external displays | A fast processor cannot compensate for too little memory or unsuitable software. |
| Travel and university | Weight, charger size, robustness and account recovery | Long claimed battery life may not match demanding apps. |
Choose for your applications
Check the published requirements for the software you rely on, including operating system, processor architecture, memory, storage and peripherals. Browser-based work is different from local video editing, programming or specialist engineering software.
Leave headroom for updates and files. A machine that just meets a minimum specification can feel constrained sooner than expected, especially where memory or storage cannot be upgraded.
Screen and input are daily tools
Compare size, resolution, brightness, finish and scaling at the distance you will use. A glossy screen can look vivid indoors yet be difficult near a window. For colour-critical work, look for independent measurement and workflow compatibility.
Type on the keyboard and use the trackpad if possible. Key layout, travel, palm rejection and webcam placement are not captured by processor charts but affect every working day.
Ports, charging and displays
List monitors, storage, card readers, Ethernet and accessories. USB-C describes a connector, not every data, display or charging capability, so check each port in the exact model manual.
USB Power Delivery can negotiate power over USB-C, but charger, cable and computer capabilities must align. Keep the supplied charger for high-demand use and verify any dock with the manufacturer documentation.
Battery, repair and support
Quoted battery tests are not a promise for your workload, brightness or network use. Reviews can show real-world variation. Also check charging speed, availability of a replacement battery and whether the charger is easy to replace.
NCSC advises considering manufacturer support duration. Operating-system and firmware updates, spare parts and service access can make a modestly specified laptop the better long-term purchase.
Security and setup
Use a strong account password and available multi-factor authentication, set up backups and keep updates enabled. Decide whether you need fingerprint or facial sign-in, removable storage controls or business management before buying.
Treat bundled security software and “AI” labels as secondary to the machine meeting your practical needs. An organised recovery plan and supported software reduce disruption more reliably than a feature badge.
Memory, storage and thermals
Check whether memory and storage are soldered, slotted or partly upgradeable in the exact configuration. Browser tabs, video calls and creative tools compete for memory; a low starting specification can be the practical limit before the processor is.
Read reviews for sustained performance, fan noise and surface temperature under the workload you use. A short benchmark does not show how a thin computer behaves during a long export or meeting.
External displays and docks
Check display count, resolution, refresh and charging through the actual port, dock and cable combination. USB-C docks can share bandwidth and power, so a single-cable desk may work differently from the product photograph.
Verify whether the laptop needs its supplied charger for sustained performance. Some docks charge slowly enough for light work but discharge a computer during a demanding task.
The final check
Before you buy
- Write down required apps, external displays and accessories.
- Check operating-system support and upgrade policy for the planned ownership period.
- Compare keyboard, webcam, screen finish and ports in person where possible.
- Verify each USB-C port for charging, display and data functions.
- Read independent battery, fan-noise and repairability observations.
- Price a replacement charger, battery and extended storage if relevant.
Match the full model and included accessories, then confirm the final price, delivery and returns terms at the retailer. COR shows supported offers where available; it does not search every seller.
Common questions
How much memory do I need?
It depends on apps and multitasking. Check software requirements and buy enough headroom because many laptops do not allow later memory upgrades.
Can one USB-C cable do everything?
Sometimes, but capabilities vary. Confirm charging, display and data support for the laptop, dock, cable and monitor.
Are long software updates important?
Yes. They can affect security, compatibility and the usable life of a computer. Check manufacturer and operating-system support information.
