First of all, it is important to choose a laptop that is better suited to you and choose the configuration of your computer according to your needs. 1. A job that needs to be done before buying. 1. First understand the main hardware functions and common sense in the laptop. The hardware is divided into CPU memory, hard disk, optical drive, motherboard chipset, and graphics card. The sound card is relatively minor. The Central Processing Unit (CPU) is a very large-scale integrated circuit that is the computing core (Core) and Control Unit of a computer. Its function is mainly to explain computer instructions and data in computer software. Currently the two major brands sold in the CPU market (ie two): Intel (Intel Corporation) AMD (AMD)
Although it is two types, it contains hundreds of low, medium and high-end CPU products. 5000, is one of the CPUs produced by AMD. 2.93G refers to the CPU's main frequency. Differentiate between good and bad methods: the more the number of cores, the more threads, the larger the CPU cache, the higher the CPU frequency, the better the performance, and the higher the price.
The memory temporarily stores the operational data in the CPU and the data exchanged with the external memory such as the hard disk. The performance of all the programs in the computer has a great influence on the computer.
A hard disk is one of the main storage media of a computer and consists of one or more discs made of aluminum or glass. The disc is covered with a ferromagnetic material.
Hard disks are mainly divided into solid state drives, mechanical hard disks, and hybrid hard disks. Most hard drives are fixed hard drives that are permanently sealed to the hard drive.
Mainly divided into solid state drive (SSD) (SSD disk, new hard disk), mechanical hard disk (HDD), hybrid hard disk (HHD); solid state disk is stored by flash granules, sata solid state, m.2 solid state, pci-e solid state .

2. What is the main purpose of knowing what you want to buy a laptop? Is it mainly used for surfing the Internet, typing, playing games, and working? Do you want to use it often? There may be different answers for different people. Some people often use computers, such as office or game games. People in this area are more dependent on laptops, while others just use laptops. Sometimes people have a strong spending power and buy laptops. The main purpose is different, of course, there will be a big difference in the choice of brand and model.
3. Carry out economic budgets. In addition to the main purpose of your laptop, the economic budget depends on how strong your economic capacity is. The main purpose of buying a laptop is to buy a laptop. You have to buy a bit better because you don’t know if you will use a laptop to do some complicated work in the future, and the higher the configuration of the notebook. The wider the scope, the better it is used, and for those with less economic affordability, the calculation is more, the budget can be less, and the configuration is as good as possible. Fourth, select several candidate laptops.
Should pay attention to the following points: 1: CPU computer a lot of calculation work is done by the CPU, graphics calculation is done by the graphics card or GPU (Graphic Processing Unit, image processor) integrated on the motherboard. The CPU is an important criterion for measuring the level of a computer configuration. The CPU mainly has two brands, Intel and AMD. In the notebook computer, mainly using Intel's CPU, some low-end notebooks will use AMD's CPU. The high-end (price >6000) CPU is as follows: Intel Core 2 i series (i7) Intel Core 2 P series (P8800, P8700, P8400, etc.) The mid-end (4000 <6000) cpu is as follows: intel Core 2>
