What should I do if the computer case shell leaks electricity? There are many types of chassis. Now the more common ones in the market are AT, ATX, Micro ATX and the latest BTX-AT chassis whose full name should be BaBy AT, which is mainly used in early machines that can only support AT motherboards. ATX chassis is currently the most common chassis, supporting most types of motherboards.

Next, let's take a look at the solution to the leakage of the chassis.

When you find that the chassis is leaking, first check whether the chassis is placed too close to other electrical appliances, or whether there are broken wires on the chassis. This is an external cause that causes the chassis to leak. You only need to put these external Factor removal can be resolved. If there is no external factor that causes the chassis to leak, it is caused by internal reasons, which may be caused by power leakage, improper installation of the motherboard, or some pins touching the chassis shell.

Solutions for chassis leakage due to internal reasons:

First, check whether the power board is in good contact.

Secondly, open the case and check whether the wiring in the case is in good contact, whether the insulation package is damaged, and whether the metal parts of the wire are in contact with other accessories and the case.

​

Third, disassemble the power supply to see if the EMI circuit of the power supply is complete, whether the plastic film or mica sheet between the spacer element and the metal casing of the power supply has lost its insulating effect, and whether the internal capacitor of the power supply has exploded. and so on. If there is a problem, you can build a high-temperature-resistant plastic film by yourself to form a shielding barrier between the component and the power supply housing. If it cannot be solved, replace the power supply immediately.

Fourth, if none of the above reasons are true, then check whether the motherboard, graphics card, and PCB inside the chassis are deformed. When this happens, it is best to use the minimized system to make the platform simpler and easier to judge, and to avoid unnecessary damage to accessories such as hard drives during the test.

Fifth, there is a PCB circuit board connected to the mainboard audio, signal, switch, and USB expansion behind the chassis. Check whether the wires connected to the circuit have insulation failure, short-circuiting or burning of components. If such a problem occurs , it can be repaired or replaced with electrician tools.

I hereby remind you that when placing the computer, it is best to place the case in a dry place to avoid short circuits caused by the relatively humid environment, and take precautions.

The reasons for the leakage of the chassis include internal and external reasons, such as power leakage, improper installation, broken wires, and humidity in the chassis environment. Check the internal structure.
