Practical tutorial: Laptop memory upgrade

  • Practical tutorial: How to upgrade the memory, expand the capacity of the hard disk, replace the hard disk and quickly migrate the Windows system without loss. As time goes by, you may encounter the need to upgrade the memory and upgrade the hard disk. If the laptop has only one hard disk Bit, you may also need to migrate the system, after all, it is too troublesome to reinstall, and there are data and files on it. Today, I will explain to you, how to upgrade and replace the memory, how to replace and upgrade the hard disk, and how to quickly migrate the system without damage. The laptop used in this tutorial is the Redmi G 2021, and the replacement of other laptops is similar. Whether it is possible to replace the laptop to upgrade, you need to consult the customer service or the official website for information, and you can search for tutorials and experience on the Internet. The main issue is whether the back cover can be opened or not. This may be different for each laptop. It is not as simple as simply unscrewing the screws. Taking my Redmi G202 laptop as an example, first of all, when we look at the bottom, we can find that there are 9 screws, so these screws need to be unscrewed. At the same time, many laptops have hidden screws, such as this laptop, the hidden screws are under this rubber pad. This requires an online search for the corresponding laptop disassembly guide. You can purchase some necessary tools online, mainly spudgers, so as to avoid damaging the laptop during disassembly. Along the seam, you can pry the pad apart, and you can see that the inside is snapped. Underneath, there is a screw. After all the screws have been removed, use a spudger, or other tool, such as a thin card, to pry the seams open, more than one can be used. After prying from the middle, slowly extend to the sides. There are buckles here, so slowly slide and pry. That's it, or try to pry it open a bit around, and you're done. It's usually easiest here. You need to pry it around the edge of the notebook, because there are clips on this edge, and then you can take off the cover and see the clips around the edge. Then look at the laptop here, focus on these, one is the battery, because we can't operate it with electricity, so we must disconnect the battery. In fact, it is to find the location of memory and hard disk. Some laptops are visible at a glance, while others, like mine, come with a cover. First, look at the connection line between the battery and the computer motherboard, and gently remove it. The space here is a bit cramped. For safety and to avoid forgetting, it is best to remove the battery and unscrew the four fixing screws. picture above shows how the battery is removed, and now you can let go and work. So first of all, the cover of the memory, we see that there are no screws, it is directly stuck, so you can just take it off. Then you can see that there are 2 pieces of memory inside, which are Kefu and Hynix particles. So what we are going to use for expansion is the 32GB memory of Jinbaida, 3200MHz high-frequency memory stick, one is 32GB, this is amazing. This memory stick has a lifetime warranty. Open the box to take out the memory, we see that there are 8 particles on one side. On both sides, there are a total of 16 particles. Judging from the logo, this is a Korean Samsung particle, which is used by many memory manufacturers, including Samsung itself. A single chip has a capacity of 16Gb, then 16x8x2=256Gb, which translates to a capacity of 32GB. To take out the memory, open the 2 metal buckles. When installing, first insert the foolproof notch correctly, then press down, and hear the sound of the "kata" metal buckle being stuck. Let's take a look at the hard disk upgrade and installation. is a cover here that needs to be unscrewed. After opening it, we saw that this laptop uses an M.2 NVMe SSD hard drive, which is also the hard drive commonly used in laptops today, in order to be thin and light. Few laptops use SATA hard drives anymore. The above picture shows the use of SATA hard disks, which are usually the pictures of solid-state hard disk expansion. Due to the large area and volume of SATA hard drives, they are less used now, but there are also a small number of laptops that have this option. So today we are going to install an M.2 NVMe SSD hard drive, which is an M.2 NVMe SSD hard drive from Jinbaida. Taking out the product, we saw the manual, fixing screws, silicone heat dissipation pad, metal heat sink, and M.2 NVMe SSD hard drive. This M.2 NVMe SSD hard drive has a capacity of 512GB. Now that the price of the hard drive has dropped, you can consider using 1TB or 2TB. This one supports PCIe Gen 3x4 protocol. This NVMe SSD uses a domestic Lianyun master controller. The rise of domestic chips allows us to use cheaper products. The installation of the M.2 NVMe SSD is to insert one side with a foolproof notch into the slot, and fix the other side with screws. M.2 SSD has different specifications, the most commonly used is 2280, which is the length. In addition, there are 2260, 2240, 22110, which are relatively rarely used. Well, the memory expansion and hard disk installation are completed. We put the cover back in place and connected the battery. Put the cover back on, start the computer and take a look before turning the screws. Running Master Lu, we see that the memory is displayed as 32GB Jinbaida DDR4 3200MHz. In the details, you can see the frequency, timing and other related information. Checking the hard disk, it shows that there are 2 hard disks, the first hard disk is the original hard disk, and the second one is the newly installed Jinbaida hard disk. In the computer management, you can see that the block is not processed, we will create it, format it, and test it again. It shows that reading and writing are the performance of high-speed NVMe SSD, which is still possible. See simply adding memory, adding hard disk is very simple. However, some friends hope to be able to transfer the system to the newly added hard disk without damage after adding a hard disk. The reasons are generally as follows:
