How to Check a Laptop Before Buying — Complete Inspection Checklist
Before paying for any laptop — new or refurbished — spend ten minutes checking: the screen (no dead pixels or marks), the keyboard and trackpad (every key works), all the ports (plug something in), the battery health, that the specs in system info match what is advertised (processor, RAM, SSD and capacity), that it runs smoothly without overheating, and that you get a proper bill and clear warranty. A genuine, healthy laptop passes all of these easily; problems show up when you actually test it. This matters most for refurbished or second-hand laptops, but it is worth doing on a new one too.
Why check before buying
A laptop is an expensive, long-term purchase, and faults are far easier to catch before you pay than to argue about afterward. Whether you are buying new in a shop or a refurbished unit, a quick, systematic check protects you from dead pixels, faulty keys, weak batteries, or specs that do not match the listing. Reputable sellers expect and welcome these checks — reluctance to let you inspect is itself a warning sign.
Step 1 — Inspect the screen
- Look for dead or stuck pixels (small dots that stay black or coloured) — open a plain white and a plain black image to spot them.
- Check for scratches, marks, or pressure spots on the display.
- Check brightness is even across the screen with no dark patches.
- Open and close the lid to check the hinges feel firm, not loose or stiff.
Step 2 — Test the keyboard and trackpad
- Press every key to confirm they all register — open a document and type across the whole keyboard.
- Check the keys feel consistent, not mushy or sticky.
- Test the trackpad — movement, clicks, and gestures all working smoothly.
Step 3 — Check all the ports
- Plug something into each USB port, the charging port, the HDMI/display output, and the headphone jack to confirm they work.
- A non-working port is easy to miss and annoying to live with — test them all.
Step 4 — Check the battery health
- If the laptop shows a battery-health or capacity figure (many do in system settings), check it — a worn battery is a common issue, especially on refurbished laptops.
- Unplug the charger briefly to confirm the laptop runs on battery and shows a sensible charge level.
Step 5 — Confirm the specs match
Open the system information and verify the laptop actually has what is advertised:
- Processor — the right model and tier.
- RAM — the right amount.
- Storage — that it is an SSD (not an HDD), and the right capacity.
- The model name matches what you are paying for.
Spec mismatches are a real risk, especially with second-hand or refurbished units. Trust the system info, not just the listing.
Step 6 — Test that it runs well
- Boot it up and time roughly how fast it starts (an SSD laptop boots quickly).
- Open several apps and a few browser tabs — it should feel smooth.
- Let it run for a few minutes and check it does not overheat, throttle, or behave oddly (loud fans, sudden slowdowns, unexpected restarts).
Step 7 — Sort the paperwork
- Get a proper bill / proof of purchase in your name.
- Confirm the warranty clearly — how long, official or seller, and where to claim it. Get it in writing.
- For refurbished/used, this matters even more — see our new-vs-refurbished guide.
