Hand computers are much cheaper compared to new computers, but the performance of computers varies a lot, because computers are updated very quickly, and the support for new software and hardware also needs to be tested before they can be determined. Some second-hand computers are actually parallel computers, especially laptops, more second-hand, this kind of computer is difficult to get maintenance and other after-sales service, but the performance and the new computer is basically the same, some of them are Hong Kong line, that is, Hong Kong licensed goods, it is possible to get repair service, but this kind of service is generally more costly, and it is difficult to get a 100 percent guarantee.
Used computers with the same new machine, some are branded machines for sale, but also with their own requirements, but the compatibility of such machines relative to branded machines to be worse, maintenance is not as easy as branded machines. If you buy such a machine, you need to pay attention to the brand and warranty period of each component. The appearance of used computers according to the degree of previous use will leave traces of use, which is the need to distinguish the color of the computer, such as the number of scratches, stains obvious degree, gloss brightness, etc. for the color of the valuation, if you buy a poor color of the used computer may hurt the buyer's psychology. Another point is that some businesses recycled used computers to change the shell, replaced with a new one, the business called refurbished machine, looks and new there is not much difference
