If you want to obtain a free warranty for IBM purchased outside China, the host must provide:
1. Purchase an entry certificate (for example, a pass or passport to or from Hong Kong)
2. Purchase invoice
3. the COA Number of the fuselage (that is, the authorization label of Microsoft's genuine operating system)
4. the laptop passes the customs duty-paid certificate
At present, some commodity merchants can provide the first three items to buyers of overseas notebook products for free. As the name suggests, the tax-paid certificate can only be obtained when a laptop purchased outside China passes the customs and has paid enough customs duties. The price of a paid notebook is almost the same as that of a laptop purchased in China, and merchants of parallel imports naturally cannot provide it to consumers.
Now some powerful overseas laptop product dealers can help the host to complete the registration procedures, or only provide procedures, the host needs to complete the warranty registration procedures. There is a big gap between the two in terms of price, but the risk gap is also great, because the user registers on his own, in this case, the dealer may provide false overseas purchase procedures or other false procedures, resulting in registration failure. In this case, the commodity dealer will not assume any responsibility.
