A second-hand laptop can be excellent value, but do not let a clean lid or attractive price replace basic checks. Use this list whether you are buying privately, online or from a refurbisher.
1. Confirm the exact identity
Record the manufacturer, full model, processor, installed RAM and storage. Similar-looking models can have very different internal specifications and operating-system support.
2. Inspect the case, hinges and screen
Check for cracks, bent corners, loose hinges, missing screws and signs of liquid. Open and close the lid slowly. Examine the screen on light and dark backgrounds for lines, flicker, pressure marks or dead areas.
3. Test every input and connection you need
Try the keyboard, touchpad, webcam, microphone, speakers and headphone socket. Test USB, display and charging ports where possible. Confirm Wi-Fi and Bluetooth rather than assuming the model includes them.
4. Ask for the battery result
Battery performance depends on age and use. Ask what was measured on that individual laptop and remember that runtime also changes with screen brightness, workload and power settings.
5. Check the charger
Confirm a compatible charger is included, that the cable and connector are undamaged, and that the laptop charges reliably when the plug is moved gently.
6. Check storage, memory and cooling
Listen for unusual fan or drive noise, check that the stated storage and RAM appear in the operating system, and ask whether diagnostic tests found errors. Unexpected shutdowns or severe heat require investigation.
7. Confirm the operating system
Check the Windows edition, activation status, update status and whether the hardware officially supports the version being sold. Make sure no previous owner’s account or data remains.
8. Read the condition and warranty wording
Condition should explain cosmetic marks rather than hide them. Warranty terms should state duration, exclusions and the process if something fails. Keep the listing and receipt.
9. Match it to your actual use
A laptop can pass every check and still be wrong for your software, screen-size preference or travel needs. Tell the seller what you will run and ask for evidence rather than broad performance claims.

Quick answers
Can I test a second-hand laptop quickly?
A short inspection can catch obvious problems, but storage, memory, battery and intermittent faults need proper testing and evidence from the seller.
What should I check on the screen?
Look for cracks, pressure marks, lines, flicker, dead areas, uneven brightness and hinge movement at several screen angles.
How do I know Windows is legitimate?
Check the installed edition and activation status in Windows settings, and confirm the device supports the operating system it is being sold with.
