What are the causes of computer hardware problems, chassis leakage, and computer chassis leakage?

The shell leaks because the wiring of your house is not grounded, and the stinky one asks that it may be a problem with the power supply, and it is best to buy a better power supply.

It may be that your power supply is too small, which makes your power supply heat high, and the wire has a burnt smell, it is recommended to replace the power supply as soon as possible and choose a power supply with high power supply!

To clean the computer case as a whole, change the power cord, see if there is a problem with the power supply of the case, if there is a problem, it is best to change one, and then you can connect a ground wire on your machine, it is very simple, just find a wire, or wire, one side is connected to the machine, one can be placed on the ground.

There is danger! To remove the power supply of dust and carbide with alcohol. Replace the power cord.

I don't know if you have ever encountered the situation of computer case leakage, case leakage is when your hand touches the case, you will have the feeling of being electrified. The following is what I have collected for you, and you are welcome to read it:

1.Leakage of electricity in the computer case caused by external reasons, such as the case being placed together with other electrical appliances, or the case touching broken wires, will cause the case to leak. For the leakage of the chassis caused by this reason, you only need to check whether there are any electrical appliances near the chassis or touch the wires, and move the location of the chassis to solve the problem.

2.Leakage of power in the computer case due to intrinsic reasons. Chassis leakage caused by internal reasons generally appears on older computers, because the chassis power supply of new computers is relatively normal, so there is generally no leakage.

If the power supply is overused, or if the weather is humid and the environment inside the power supply is damaged, leakage may occur. The more common reason is that because there is a lot of dust inside, coupled with the supermarket, a path will be formed between the internal components and the metal shell of the power supply, which will lead to leakage, so it is necessary to clean the dust of the computer regularly.

3.Caused by static electricity, there are also rare touches to be electrified, you think it is the computer chassis leakage, and then there is no electricity when you touch it, it is static electricity, static electricity is fine, don't care.

When we find that the computer leaks, we must first determine whether the electrical plug-in board used has a good grounding design, and if not, we must replace it immediately, because if there is a good grounding, even if there is leakage, the damage and loss can be minimized. Secondly, you can also open the chassis, look at the wiring inside and outside the chassis, see if the insulation package is damaged, whether the metal part of the wire is exposed to other accessories and chassis, if there is, it should be replaced immediately, so as to avoid computer leakage.

1. The way to release static electricity is to unplug all the external wiring on the main chassis (notebook, you need to remove the battery), and then press the host switch about 5 times, the static electricity inside will be consumed, and then it will be normal to turn on the computer.

2. Connect the real ground wire to the host. Use a regular plug-in board with grounding, the premise is to ensure that the indoor wall electricity has a real ground wire.

3. Connect a ground wire with insulating skin to the heating pipe or metal water pipe on the computer case, generally the current heating pipe has equipotential, even if there is no equipotential connection, it can effectively remove static electricity.

Since the root cause of the live wire is that there is no ground wire installed, the easiest way is to connect a wire directly from the casing, and connect the other end of the wire to the metal water pipe. When connecting, you need to scrape off the anti-rust layer on the water pipe, and tighten it several times. As long as we connect the ground wire, the chassis of the host will not turn red when we test it with a voltage tester.

However, this connection method is a temporary emergency use, and the home must ask a professional electrician to install the ground wire correctly to prevent the water pipe from being energized due to the "formal leakage" of other household appliances, and the injury accident occurs.

The root cause of the computer case being electrified is because there is no ground wire installed in the home or the grounding is poor. Because the computers currently sold on the market are certified by CCC, the power supply certified by CCC must use EMI filter circuit, because the filter circuit has capacitance and communication with the live wire and the ground wire, if the ground wire is not installed at home, there will be more or less "electrified" phenomenon on the surface of the case, which is a normal phenomenon. Even if we use a voltage tester to test the surface of the case to be "red", this static electricity will not cause harm to the human body, but we will occasionally touch the case with a slight "electric shock" feeling.
