Practical tutorial: How to upgrade the memory,https://www.zteamsshop.com/brooklyn-nets/kevin-durant.html 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,https://www.zteamsshop.com/los-angeles-lakers/shaquille-o-neal.html 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. https://www.yteamsshop.com/boston-bruins/patrice-bergeron.htmlThe 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. https://www.uteamsshop.com/chicago-blackhawks/jonathan-toews.htmlThere 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, https://www.tteamsshop.com/atlanta-falcons/marcus-mariota.htmlthen 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:

After the addition is complete, https://www.ateamshops.com/atlanta-braves/freddie-freeman.htmlyou can place the sub-routes in the desired location and start up. Wired Mesh networking is the most ideal networking method at present, with the most stable network quality and the lowest requirements for routers, and the wireless network speed is almost not attenuated. Wired backhaul requires network cables to be deployed in advance to link all routers. Therefore, using wired mesh networking requires network planning, deployment of network cables, and electrical ports at the connection ports. Do not connect the network cable directly before wired networking. You need to perform wireless mesh networking first, and then connect the network cable after completion. Things to pay attention to: The most recommended wired mesh is that the main and sub routers are directly connected to the network cable.https://www.vteamsshop.com/boston-celtics/kyrie-irving.html We must first close the DHCP service of the optical modem itself, which is the basis for the subsequent operations. After the optical modem is changed to bridge mode, the network configuration can be more flexible. And because the performance of the optical cat is generally weak at present, this operation can also improve the network performance to a certain extent. Next, I will briefly talk about the following methods:This is an ideal solution. In this case, the optical cat bridge is optional. The dial mode of the light cat can be maintained unchanged. Using a Mesh router as the main route, the weak current box only has a light cat, and the network cables are concentrated in the living room. The switch is only used as the main routing port, and there is no mandatory requirement. In the case of a small number of sub-routes, it can also be directly connected to the main route. If the area is large and more devices are required, you can add a gigabit switch,https://www.wteamsshop.com/atlanta-braves/freddie-freeman.html connect the main route to the switch, and then lead out other network cables from the switch. The optical modem is changed to bridge mode and dialed by the main router, if not, it can not be changed. 2. The network cables are gathered at the position of the weak current box, which is generally used for more installations. The network cables in all rooms are converged to the weak current box. In this case, a number of different schemes can be used depending on the specific situation. ①: There are replaceable network cables. In this case, we lead three network cables from the weak current box to the living room. If there is no need for IPTV, it can be changed to two. One is connected to IPTV (nothing can be ignored), one is connected to the WAN port of the main router, then the other is connected to the LAN port of the main router, and then the network cable is connected to the switch 1 in the weak current box, and the other network cables are connected to the switch. First perform wireless mesh networking, and then take the sub-router to other rooms and plug in the Internet cable. https://www.xteamsshop.com/san-francisco-49ers.html Single-line multiplexing Mesh networking + IPTV optical modem is set to bridge mode, and the DHCP function is disabled. If this premise cannot be met, this method cannot be used. In this case, 2 gigabit switches are required, and the VLAN function of the switches needs to be used to separate the IPTV data from the Internet data. This method has higher network requirements. The switch has a management IP address by default. When there are two network management switches in the network, you need to modify the default management IP address to prevent network device IP conflicts. Divide the IPTV interface into one VLAN, and divide the router's Internet data interface into another VLAN. The two do not communicate with each other. Setting VLAN may be too complicated for Xiaobai, you can use the following AP mode solution. AP mode Mesh networking In this mode, a soft route is required as the main route. If the requirements are not high, an optical modem can also be used. Other mesh routers only provide wireless functions. At this time, the mesh router needs to be downgraded to network through AP mode. In AP mode, all routers only support wireless functions, and some high-end functions such as firewall will not be available. Mesh settings in AP mode are relatively simple and easy to operate. For example, if the soft route IP is 192.168.2.1, we will adjust the Mesh main route to 192.168.2.2. Then perform wireless Mesh networking, and close the main route DHCP after success. Switches can be omitted according to their actual needs. If there is no soft route, you also need to use AP mode, connect the optical modem to the switch, connect the sub-router to the switch, and the optical modem is responsible for dialing and gateway. However, the performance of optical cats is generally weak. If the demand is not particularly high, this method can be considered. The above are several Mesh networking solutions. We summarize it as follows:

This week, Huawei held a new product launch event and officially launched a new generation of Mate50 series flagships. https://www.zteamsshop.com/It is reported that the new Huawei Mate50 series provides four models: Mate50, Mate50 Pro, Mate50 RS Porsche Design, and Mate50 E, and brings a variety of new flagship-level support. Official news shows that this new flagship product Huawei Mate50 series supports Beidou satellite messaging hardware capabilities, and is the industry's first mass smartphone that supports Beidou satellite messaging. When you are in an environment without ground network signal coverage, such as in desert and no-man’s land, in distress at sea, and in earthquake rescue,https://www.yteamsshop.com/ you can send text and location information through the Changlian APP to keep in touch with the outside world, and support multiple locations to generate trajectory maps. However, with the official release of the Mate50 series, many users have also begun to pay attention to more details of this new feature. At present, Huawei has also given an official introduction to these contents. It is reported that the Beidou satellite messaging function of Huawei Mate50 series does not require inserting a SIM card, and can communicate with the outside world through a satellite network in an environment without terrestrial network signal coverage.https://www.uteamsshop.com/ When the mobile phone has no signal (no cellular network/WLAN network coverage), and in an open and unobstructed environment, you can send messages through the Beidou satellite in the "Beidou Satellite Message" service number in the Changlian App. However, satellite communication only supports sending satellite messages in the Changlian App, and does not support Internet/call/video functions for the time being. During the public testing period, the monthly limit is free to use, and you will not be able to continue sending after the quota is used up. It should be noted that the receiver needs to be in an environment with terrestrial network coverage to receive Beidou satellite messages. If the receiver mobile phone has installed and activated the Changlian App version that supports Beidou satellite messages, it can receive both Changlian messages and SMS messages; if the receiver phone does not have the Changlian App installed, it can only receive SMS messages. As for the specific functional support models, Huawei officially stated that currently only Huawei Mate 50, Mate 50 Pro,https://www.tteamsshop.com/ Mate 50 RS Porsche Design supports sending messages through the Beidou satellite network, and does not support receiving messages through the Beidou satellite network. However, at the same time, it is also reported that this function may also cover other models of Huawei in the future, and related revelations have appeared one after another. Recently, blogger @pengpengjunjiao mentioned in the revelations, "Huawei Mate Xs 2 folding screen may indeed support Beidou satellite news in the future." "It should be noted that Beidou satellite news requires hardware foundation, and Mate Xs2 is equivalent to The hardware capabilities were integrated in advance, but the application was not tested and released at the time. The upgrade of Beidou satellite news should be supported in the future." According to the statement mentioned in the revelations, the Huawei Mate Xs 2 folding screen flagship currently on sale is expected to support follow-up support. this function. In addition, this time the Huawei Mate50 is equipped with Snapdragon 8+ 4G, and the latest news shows that it may be supported by 5G mobile phone cases. The blogger @Factory Director Shi Guan mentioned in a recent revelation, "The Huawei Mate50 series 5G mobile phone case is coming soon, probably around October." Judging from the information mentioned in this revelation, it is possible to The mobile phone case products that provide 5G support for the Huawei Mate50 series are expected to arrive next month, and interested users can stay tuned. Of course, given that there is no definite official news for the time being, the actual product situation remains to be verified.<br>
