You will find that vendors use the terms second-hand, used, refurbished, and new interchangeably. It is very inaccurate and you should know what the term refurbished laptop and used laptop means in order not to be buying something unwanted or un-bargained for.
As opposed to a used laptop, which typically did not undergo any checks before selling, a refurbished laptop is thoroughly checked, reconditioned, and returned to its as-new status. This is very different from a used laptop or used notebook even when it is offered to you with the same assurances. Vendors often try to sell a used laptop as a refurbished laptop in order to charge more for the laptop.
A refurbished laptop often comes from the manufacturers that made it as they may be returned to manufacturers with minor faults, from scratches to software glitches. A company will inspect and restore the laptop to working as new and for all intent and purposes be new. However it is not new and cannot be advertised as such, that is where reconditioned or refurbished laptops come in.
Buying a refurbished laptop in other words will allow you to buy a laptop with much higher specs than you originally anticipated for a much lower price. Look out for the price of a used laptop as oppose to a refurbished laptop. A used laptop should be significantly cheaper than a refurbished laptop, the same as a refurbished laptop must be cheaper than a brand new laptop.
A used laptop or used notebook will not operate exactly like a new or refurbished laptop and you can expect minor problems, depending on the price you pay. A refurbished laptop on the other hand must work in exactly the same manner as a new laptop. If someone wants to charge you the price of a refurbished laptop for a used laptop then the used laptop must have absolutely no issues or problems.
