According to your description, I suggest you refer to the following information:
1. In general, as long as you buy this machine in a regular HP store, there will be no problem you are worried about.
HP has always attached great importance to and strictly controlled every link of product circulation. Hewlett-Packard Company insists that all returned notebook computer products (that is, notebook computer products equivalent to new products in terms of performance and reliability) should be strictly marked as refurbished machines in relevant product information and packaging, and strictly abide by national laws and regulations in all aspects. HP resolutely prohibits the sale of refurbished machines as new machines.
2. If you want to inquire about the information related to machine maintenance, you can try to contact the local HP Gold Service Center for consultation.
For the contact information of HP Gold Service Center, you can use the following official links to inquire:
