Buying a used laptop: compare specifications and condition
Guidance from Alemiin
Updated:
A brand name and screen size are not enough to choose a laptop. Start with the work you need it to do and compare the complete configuration. The same model may be sold with different processors, memory and storage.
Write down the full configuration
Ask for the exact processor model, RAM, storage type and capacity, screen and operating system. Check the software maker's requirements for your applications; a ‘gaming’ or ‘business’ label is not evidence of performance.
- Ask for a picture of system information with personal details excluded.
- Ask whether the configuration has changed and which parts have been repaired.
- Confirm the included accessories and whether the charger matches the device.
Run a functional check
With permission, start the laptop from a powered-off state and try an ordinary task. Observe it without installing unfamiliar software or opening the seller's private files.
- Try the keyboard, touchpad, camera and speakers.
- Inspect the screen for damage, marks and uneven lighting.
- Try the ports you need, Wi-Fi and charging.
- Look for visible damage to the casing and hinges.
Assess the battery without false promises
Ask how long the battery lasts for the seller's tasks and whether it has been replaced. In Windows, a battery report provides extra information about usage and estimated capacity. One report or percentage does not guarantee how many hours it will last with your applications.

Agree on the handover
Check whether the device can be used without accounts or management belonging to a previous owner. The seller should back up and remove their data. Record the price, currency, accessories, faults and any warranty or returns terms. Include the cost of missing accessories in your comparison.
