When you’re searching for a refurbished laptop you will find that a lot of vendors use the terms ‘refurbished’ and ‘second-hand’ or ‘new’ more-or-less interchangeably. This is inaccurate, and it risks you ending up with something you didn’t bargain for.
A refurbished laptop is typically one that has been thoroughly checked, reconditioned and returned to as-new state. It should work as well as one straight out of the factory. This is very different to buying a laptop that is simply described as ‘used’, which offers few of the same assurances.
