Going by definitions, refurbishing something means decorating and loading something with new and useful things to make it more useful than it was before. On same lines, a refurbished laptop is a previously used or returned laptop that has been restored to its original condition and functionality by the manufacturer or a third-party refurbisher.
During the refurbishing process, the laptop is thoroughly inspected, tested, and repaired if necessary. Parts may be replaced, software may be updated or reinstalled, and the laptop may be cleaned and polished. Refurbished laptops come with a limited time warranty for assurance of their quality
