What should I do if the computer case leaks? Causes and handling of leakage of computer case
The computer case is an indispensable accessory for the desktop computer. It plays a role in fixing and protecting various parts of the computer. In addition, the computer case has an important role in shielding electromagnetic radiation, and many friends will often be reflected in the computer case after using it for a period of time. So, this means that the computer case is leaking, so what about the computer chassis leakage ? The following decoration home decoration network Xiaobian will bring you the reasons and treatment methods of computer chassis leakage, I hope to help everyone.
What should I do if the computer case leaks?
Analysis of the causes of computer chassis leakage:
1. External causes cause leakage of computer case:
Sometimes the leakage of the computer may not be caused by the main board inside the computer case or the leakage of the power supply. Sometimes, the leakage of the chassis may be caused by external causes, such as the chassis being placed too close to other appliances or the chassis being touched. Broken wires, etc., causing the chassis to leak. For the leakage of the chassis caused by this external cause, the solution is very simple. When we find that there is leakage in the chassis, check whether there are any electrical appliances or any wires in the vicinity of the computer chassis, and the position can be solved by moving the position.
2, the internal cause of leakage of the computer chassis:
Internal causes of computer chassis leakage is the most common computer leakage, so which hardware inside the computer case is prone to leakage? This is actually very well known. It is mainly found which hardware is in contact with the chassis. For example, the power supply is the most likely to cause leakage of the chassis. The other is that if the motherboard is not installed properly, or some component pins touch the chassis, It is prone to leakage.
The handling method of computer chassis leakage:
1. If leakage is found, we must first confirm whether the electrical plug-in board used by us has a good grounding design. If it is not replaced immediately (including the more common wall-mounted electrical socket in the home), it has good grounding, even if it is generated. Leakage can also minimize damage and loss.
2. Open the chassis and look at the wiring inside and outside the chassis. The insulation package is not damaged. The metal part of the wire is exposed to other accessories and the chassis, and it will be replaced immediately. Or directly select the wire wrapped with nylon mesh, which can also achieve better insulation effect.
3, the problem of wire and socket grounding is ruled out. In view of the previous analysis, the biggest cause of leakage of the chassis is the power supply. Let's start with the power supply, disassemble the power supply, see if the EMI circuit of the power supply is complete, and the spacer components are Whether the plastic film or mica sheet between the metal casing of the power supply has lost the insulation effect, and there is no explosion in the internal capacitance of the power supply. If there is a problem, you can create a high temperature resistant plastic film, in the component and the power supply. A shield is formed between the outer casings. If it cannot be solved, replace the power supply immediately.
4. Finally, check the motherboard and graphics card inside the chassis to check whether there is any deformation of the PCB board, etc., resulting in direct contact with the chassis. The method of inspection is preferably to use a minimizing system, on the one hand, to make the platform easier to judge, and on the other hand to avoid unnecessary damage during testing of components such as hard disks.
5, finally check the chassis itself, behind the front panel of the general chassis, there is a PCB circuit board that connects the motherboard audio, signal, switch, USB extension, we also need to check whether the circuit board and the wire on the connection circuit board are insulated. Failure, component short-circuit, burnout, if any, can be repaired or replaced with simple electrical common sense and electrical tools.
6, of course, we can also put the chassis into a relatively dry position (such as the original location is more humid and easy to cause short-circuited wires), replace the bottom of the insulated shoes and other methods, to conduct a full range of judgments, and finally find the main cause of leakage.
The above is how the computer case leakage caused by Xiaobian brought you? I think you have a basic understanding of the leakage of the computer chassis after reading this article. If you want to know more about decoration consultation, please click to enter the decoration knowledge channel.
