How do you know if the chassis has static electricity, and what should you do if it does

Just use the electricity written test on the line, if it is electrified, see if the electricity at home is two, there is no ground wire itself, the old building and the cottage are basically two kinds of electricity, you can lead the wire on the chassis to ground, and again, the ATX power supply if the EMI circuit itself will make the chassis electrified, not normal without it, so if the body does not have a great reaction, don't care about him, see what kind of situation you are?

If it is connected to the radiator in the north, the other end is tied to the conductive place behind the chassis, don't touch the electronic components, and the southern one is more troublesome to use to be grounded, and you can't ignore the classics, which is very damaging to the computer.

First of all, the chassis must be static, try it with a tester pen to know!

Secondly, pay attention to some anti-static measures, such as paying attention to humidity, etc.!

Just make sure you have a grounding wire in the three phases of your power plug so you don't have to worry about static electricity, make sure there is a grounding wire and it's good.

Whether there is static electricity or not, it must be connected to the ground wire, one end to the ground, and the other end to the chassis.

There is no static electricity on the chassis, only you may have static electricity yourself, and the chassis may bring a certain amount of electricity because of the power supply because it is not well grounded, so you need to be grounded according to the upstairs to protect you from being electrified.

It's very simple, touch the chassis with your hand, and you can measure and discharge both :)

Methods of discharging static electricity, 1It is to unplug all the external wiring on the main chassis (notebook, you need to remove the battery), and then empty press the host switch about 5 times, and the static consumption type inside will be bent, and then it will be normal. Rows of branches.

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

Connect a ground wire with insulating skin to the heating pipe or metal water pipe on the electric bulky brain case

Caused by not having a good grounding wire!

1.The most important and decisive factor is also the decisive factor. Problems with the power supply itself.

The power supply you plugged in itself has strong static electricity, and there is no ground wire, so it causes serious static electricity on your computer. If you don't believe it, switch to a different place to connect to the computer to ensure that there is no static electricity. Static electricity is not just about electricity, it will burn out the hardware.

I burned two 9600 graphics cards just like that.

2.The air is humid, and this is a supporting factor.

3.It may be that there is a slight short circuit in the chassis that is causing leakage.

Solution. 1.Replace your power supply. Plug in the computer from another location. It's a good idea to change the computer at the same time. The problem is usually absolutely solved.

2.Connecting to the ground wire, connected to the concrete floor, is definitely a good way, for the sake of hardware. You don't want to burn out your graphics card too.

Electricity may be caused by humid air, or it may be caused by power supply. Static electricity can damage computers. Usually you can put down static electricity for a while.

The specific method of discharging static electricity: unplug the power cord behind the case, and then press the computer start switch, which can release static electricity. Press a few more times.

Tie a wire to the screw at the back of the case, and then ground the other end, so that the electricity can be channeled to the ground.

Generally, it is caused by excessive dust accumulation in the chassis without a grounding wire on the power plug.

Method 1Use a hair dryer to remove dust, mainly inside the power supply. General problems can be solved2

In the place where there is electrostatic inductance, connect a wire (can transmit electricity) to connect the ground wire or heating pipe, the purpose is to guide the static electricity, as long as it is close to the computer and has the ground can guide the current of the object.

3.The cost-effective way is to directly replace the source of the problem, generally no grounding wire may be the power socket is not grounded, so only by replacing the chassis power supply, the general problem can be solved.

Do not plug in the power socket of the host, plug in the three holes on the wall, and there is a grounding wire inside.

Computer static electricity is caused by the fact that the wiring board you connect to has no ground wire, change to a wiring board with a ground wire, but first the plug must have a ground wire, it is really not possible to connect an external wire to the chassis; The U flash drive crash analysis you are talking about is not static electricity, but a virus, and it is recommended to kill the virus.

Take a copper wire and remove both scalps to expose the copper wire.

One end is grounded and the other end is connected to the chassis.

OK. The computer needs three-phase electricity. i.e. fire. Zero.

Earth. The reason is that you don't have a ground wire.

It is mainly caused by the fact that your access circuit is not installed with a ground wire.

The case is energized because you are not connected to the ground wire, the 220V working voltage is connected to the power supply converted to 24V voltage to supply power to the motherboard, and the motherboard will provide the power to each accessory, and the excess power will be attached to the chassis, if the ground wire is connected, this part of the power will flow into the earth. Because you don't, you stick to the case until you touch it. At this time, electricity will pass through your body and flow into the earth.

Not if your feet are insulated from the ground.

If you don't want to modify the circuit or something, you can ignore it, and the 24V voltage will not kill people.

If you want to remodel, the most fundamental thing is to modify the access circuit of the house, connect more ground wires, and then use three-pin sockets and plugs. (The two-pin socket and plug are the live wire and the neutral wire, and the extra pin of the three-pin is used to connect to the ground wire). A simple modification is to find wires, connect the case shell (where there is metal) and earth (or iron pipes, and the metal of the building necklace can be).

I'm not afraid of lightning in my case. It's normal for your chassis to have static electricity, so it's a good way to reduce static electricity and buy a better power supply!

The situation you are talking about is a leakage. If your feet don't touch the ground, it's okay to touch the 220V electricity directly (don't imitate, this is still dangerous), many of the electrical work is live, as long as the foot hits the ground, it forms a loop with the earth, resulting in electricity.

The chassis has static electricity???

Pay attention to the possibility that there is a leakage somewhere, open the case, take a pen and try it.

Estimated to be a case power issue.
