Before you meet the seller
Decide what you will use the laptop for: school, office work, design or programming. Note the model name and look up its specifications. Ask the seller for the exact model, the storage type (HDD or SSD), the RAM size and the battery condition.
Inspect the body
- Look for cracks near the hinges, bent corners and mismatched screws, which can mean it was dropped or opened.
- Open and close the lid several times. It should feel firm and quiet.
- Check every port: USB, HDMI, charging, headphone, card reader.
- Look at the vents for heavy dust or signs of liquid.
Test the screen and keyboard
- Show a white, a black and a coloured page to check for dead pixels, patches and backlight bleed.
- Look for flicker or lines when you tilt the lid.
- Type in a text document to test every key.
- Check the trackpad, both buttons and two-finger scrolling.
Check the battery and charger
Ask how long it lasts and unplug the charger during the test. A laptop that dies in a short time needs a new battery, so use that when you negotiate. Check that the charger is the correct one for the laptop and the plug is not loose.
Check the storage and performance
Open Task Manager and see the RAM and disk. Open several programs and a browser with a few tabs. Watch for freezing. In Windows, open This PC and confirm the drive size matches what the seller said. An SSD makes a big difference in speed.
Check heat and fan noise
Play a video for ten minutes. A laptop that gets very hot or whose fan screams quickly may need cleaning or have a cooling fault.
Check software and ownership
- Confirm Windows is activated (Settings, then System, then Activation).
- Check for a BIOS or administrator password. You should be able to remove it.
- Ask whether the laptop has been repaired or had its parts replaced.
- Avoid sellers who rush you or refuse tests.
Ask for a warranty and a receipt
Ask for a short warranty and a receipt with the seller's name and number, even for a small purchase. A seller who stands behind the laptop will agree to this.
Frequently asked questions
What does UK-used mean for a laptop?
It means the laptop was used in the UK and then imported for resale. Condition varies widely, so test each one.
What is the first thing to check on a used laptop?
Check the battery, screen and storage health, and confirm that the laptop is not hiding heat or fan problems.
Should I buy a used laptop with an HDD or an SSD?
An SSD is much faster. If a good laptop has an HDD, ask the seller or a technician about replacing it with an SSD.
This guide is general advice. Every device and business is different, so if you are unsure, ask a technician before you act.
