6. Check the motherboard. (mainly check whether the accessories and CD in the motherboard packaging box are complete, and whether the stickers on the processor and graphics card slots on the motherboard have passive traces)
7. Check the memory. (Check the gold finger for scratches caused by repeated plugging and unplugging: immediately call the manufacturer's inquiry number to check whether a box of memory is genuine)

The first thing to consider is whether the notebook you choose meets your own needs, including purpose and budget.
Secondly, we need to look at the after-sales of notebooks, because problems will inevitably occur during use and need to be after-sales.
Finally, when buying a machine, check whether the existing machine is a refurbished machine. From the appearance, first of all, look at whether the packaging sealant tape is intact, and secondly, look at whether there is dust between the notebook radiator and the keyboard seam. If it is a new machine, it should not be. Finally, you can bring your own USB flash drive, install the necessary 360 hard armor master, or Master Lu, and check the internal hardware use and factory conditions of the notebook!
