CCW share: want to upgrade the notebook? First understand how to dismantle the machine!

Limited by the budget, it is difficult for us to purchase laptops in one step, so there is a potential need to upgrade the memory and hard disk by ourselves. In addition, the long-term use of laptops, internal fans and cooling fins are easy to be filled with dust and fur, which will affect the heat dissipation, resulting in CPU / GPU frequency reduction, and then affect the performance. Therefore, we need to master certain skills to deal with the possible upgrading and dust removal operation in the future. < / P > < p > as the saying goes, “if you want to do a good job, you must sharpen your tools first”. We need to prepare a screwdriver and a crowbar in advance for notebook disassembly. Considering that there are cross, meter, Y-shaped and star shaped screws for fixed notebook, it is recommended to buy a set of screwdrivers with all common bits. The market price ranges from 9.9 yuan to 100 yuan. The steel quality and magnetic absorption effect of products with higher prices are better. < / P > < p > many laptop back covers are fixed by screws of various lengths, so be sure to remember the sequence of screws when disassembling, and keep screws of different types separately. In addition, some notebooks have fixed screws hidden behind the warranty seal, rubber foot pad or notebook. Be sure to find and screw them out before dismantling the machine. < / P > < p > most laptops can remove the bottom cover by unscrewing all the screws on the D side. For a few products, we need to start from the C-side palm rest, but no matter which structure, we need to pry the cover off along the fuselage gap. < / P > < p > in theory, a discarded bank card or membership card can do it, but for products with more precise structure or all metal integrated design, only professional crowbar tools can be inserted into the gap. < / P > < p > there are numerous tenons in the inner layer of the bottom cover of the notebook, so it can not be directly separated from the body after unscrewing the screws. We need to insert the crowbar along the larger gap, and then slowly open the back cover. In this process, the most taboo is “making great efforts to make a miracle”. The products represented by Xiaomi notebook Pro still have two groups of hidden tenons in the center of the back cover. If the snap is broken due to violent disassembly, it is better to use suction cup tools to separate the back cover from the vertical direction. < / P > < p > if there is a warranty label on the screw hole of the bottom cover of the notebook, please consult the manufacturer’s customer service before dismantling the machine to see if the warranty will be lost if the machine is disassembled for upgrading or dust removal. If you can’t remove the bottom cover by unscrewing all the screws, it may mean that the notebook has a unique structure. It is recommended to take it to the customer service center for processing. < / P > < p > today, 99% of the new notebooks have integrated back cover, which no longer reserves a separate expansion bin for the memory and hard disk, and the battery can’t be disassembled directly. The internal structure can only be seen after the whole bottom cover is removed. < / P > < p > we need to remind you that you must unplug the power cord and make sure the laptop is turned off before you screw the bottom cover. Before upgrading the memory, hard disk or removing or replacing other hardware on the motherboard, it is also necessary to unplug the cable between the battery and the motherboard, and release static electricity by washing hands. < / P > < p > the battery, touch panel, fingerprint recognizer and other functional modules inside the notebook are connected to the motherboard through the cable, and the design of various cable interfaces is similar. You need to push up the buckles on both sides of the slot to pull out the cable, and push down the buckles to fix it after re inserting the cable. < / P > < p > finally, let’s take the most representative game book as an example to show the basic structure of the notebook. If you are interested in upgrading the memory hard disk and removing the cooling fan for dust removal, please pay attention to the follow-up report of cfan.
