Buying a Used PC: What to Check Before You Pay
Exact specs, real age, a battery report and disk health — plus a hands-on test routine and the golden rule: a price far below market usually means something is being hidden.
Before buying, ask for or check
- Exact specifications: processor, RAM, storage, graphics card — do not settle for "it's powerful"; ask for the concrete details.
- Real age: the original purchase date if possible, not just "it's only a few years old".
- Battery health (for laptops): ask for a report
via
powercfg /batteryreport— it shows current capacity against the original. - Disk health: check against the warning signs of a failing SSD or the HDD equivalent.
Test it in person if possible
- Turn it on and let it run for a while — confirm it does not shut down or restart on its own under normal use.
- Open several programs at once to verify that the claimed RAM matches what Windows actually detects.
- Inspect the case visually for damage, and (if you can open it) the inside for excessive dust or signs of poor maintenance.
Warning: distrust prices far below market for the advertised specifications — it can point to components with hidden problems, or specs exaggerated beyond reality.
Tip: ask specifically whether Windows is an original licence tied to the machine, or whether you will need to activate it yourself afterwards.
Frequently asked questions
How do I check the real battery health of a used laptop?
With the powercfg /batteryreport command in PowerShell, which generates a report showing current capacity compared with the original factory capacity.
Is a very low price for the advertised specs a good sign?
Not necessarily — distrust prices far below market, as they can point to hidden component problems or specifications that are not entirely accurate.
