I bought a computer power box today and found that the vent leaked too much, which will cause the po

That's fine, there's no need to worry.

It's no problem not to change, you don't need to care too much, although chassis leakage is not a common phenomenon, but there are quite a few people who have encountered it, such as me. You don't have to worry about it, you're not playing with the case!

Here are two ways to eliminate this "leakage" phenomenon.

The best way is to use three-wire power supply, so that point A has a good grounding, and the shell and chassis of the power supply will not be "electrified". (This method is recommended).

For users who cannot use the three-wire power supply for various reasons, users can make a ground wire, insert a one-foot-long iron wire into the relatively wet ground, and use the wire to connect the iron wire with the metal steel plate of the computer case. If the previous two methods can not do the user, do not need to pay attention to this leakage current, because it will not cause danger to the human body, some users use a wire to connect the computer chassis with the water pipe at home, although this method can solve the problem of leakage current, but it is more unsafe, because the grounding effect of the water pipe is unstable, in case the computer really leaks, it will be very dangerous, this practice is not recommended.

Because a certain cable in the chassis is tied to the chassis, this problem is very troublesome, and it is necessary to disassemble all the things in the chassis and reinstall it to troubleshoot. Or it's a case power cord quality issue. I've tried removing the original power cord from the case and attaching the power cord to the monitor.

The test was electrical, and the light did not turn on.

Normal, it's your ground that isn't connected. The best (3 heads) for you to sit on the ground wireOtherwise, you'll have electricity leakage.

There is no need to change it, there is also a change one.

Everyone says that if you choose a consumer product, you can have multiple models of multiple brands to consider, but if you want to choose a business model, then it has to be the ThinkPad! I have read the parameters and introduction of SL410 510, which is worth considering for the landlord!

Please seek medical attention for a gout attack, baking soda can relieve it, but please go to the hospital for specific conditions.

There are many reasons why the power supply can't be turned on, the power supply is broken, there is no power, and so on.

If the power supply is used for a long time, and the dust is not cleaned without maintenance, etc., leakage and static electricity can cause the components to burn out.

The voltage is unstable, especially when the voltage is too high, this phenomenon is relatively rare in brand power supplies, because the adaptation of high-quality brand power supplies is relatively wide. Inferior power supply is easy to burn.

The power supply is rated for insufficient output power and is overloaded. The component is severely heated and damaged.

The use of inferior miscellaneous power supply, the quality of the components itself is poor, the power is false, and the burnout rate is very high.

Bugs and other insects enter the inside of the power supply, causing a short circuit and burning out the components.

If the power plug and socket are not in good contact, the spike pulse current will instantaneously break through the weak components with low withstand voltage.

Try to change the power socket to a good one, how much w is your power supply, it is recommended that you buy a 400w, large games, and some hardware, it is very power-consuming, insufficient power supply or long-term high temperature is easy to cause accidents.

This should have nothing to do with the rain, it should be somewhere the short circuit caused the heat to be too high, the wire can not withstand it, or the resistance box is unqualified, that is, the computer is not connected to the network, and it can burn out.

It is possible that your network cable has not been unplugged on a rainy day, and it is also possible that the network cable is connected and the motherboard and power supply may be damaged. Another possibility is that the grounding of the power strip is not good, which can also lead to the power supply burning.

Just add a ground wire, and it's generally fine.

Apparently 2.

If the Y capacitor is broken down, it is generally open and will not produce leakage current. In case of a real short circuit, it is equivalent to a primary short-circuit, and there will definitely be a big problem (such as burning the motherboard, electrocuting people, etc.).

In order to better pass EMC, the power supply generally chooses to add Y capacitors. Once the Y capacitor is added, the original UA-level leakage current will increase, but at most it is also a MA-level current, so it will be felt by people, and the electricity will not die.

The leakage current is tested by disconnecting the Y capacitor at the time of certification, so the test result will be smaller. Moreover, the Y capacitor itself is a safety device, which has a certificate, and the safety regulations require additional discharge measures for large-capacity capacitors, so it is a normal situation.

If possible, connect the case to the ground.

If there is a problem with the graphics card, directly reverse the factory, and don't play games anymore.

Yes. However, there is no professional test for this thing, and it cannot be tested only by feeling. We are not professionals, and the best way to do this is to eliminate them.

First of all, start with the graphics card, change a good graphics card to test, if the graphics card is good, change the memory, and change the CPU if the memory is good. There will always be something that is broken. If it's a motherboard, return it for repair.

Sometimes large fluctuations in mains voltage can also cause damage to electrical appliances, not to mention precision instruments such as computers that require high current.

You look at the dealer to test, replace the parts one by one, and there is no condition in your own home, otherwise you will have to deal with dry hair.

It should be, the power supply is broken, the voltage is unstable, in case of a sudden increase in voltage, some of your parts inside will burn out, I advise you to change the power supply quickly.

There is that chance, but the probability is small, so try changing the motherboard.

First of all, you need to check the problem with the line, if there is no problem with the line, then you need to check the configuration of the computer! The quality of some computer lines is not very good, which will cause the host to be hot, so the problem of adding the power supply may cause the host line to soften and burn out the motherboard, so when configuring the computer parts, you should see what kind of parts it is!

It's completely a sin that is not willing to spend a little money!

The so-called "leakage" of the computer power supply is caused by the special structure of the computer power supply.

In accordance with national regulations, the computer power supply must have a filter circuit to prevent high-frequency harmonic interference, which is called "EMI filter circuit" in the industry.

The existence of this circuit will produce a theoretical voltage of 110V on a chassis with poor grounding, but its current is very small, less than, much smaller than the safe current of 10mA in the human body. So the electric pen will light up, but people will only feel numb and startled.

Solution: 1] The most fundamental way is to use power plugs and sockets with grounding protection connectors;

2] If there is a power cord with a grounding plug, please try to change the power cord or change the socket. Prevent poor grounding contact.

3] Clean the power cord in the computer case, and suspend it as much as possible to reduce the induced electricity in the case.

To be precise, it's a problem with the power supply, you definitely don't have a grounding wire, you use a three-pin socket, the grounding plug must be connected to the ground, or pull a grounding wire to the chassis. Another thing is to open the chassis, disassemble the power supply, and transform the incoming power plug. The transformation method is as follows:

Open the power box, you will see the back of the female socket of the incoming wire, it is three binding posts, two of them are soldered with soldering and two resistors and one capacitor with soldering, you just need to remove the two resistors at the head of the grounding post, which means that the neutral wire and the live wire are not connected in parallel with the resistance to the ground. Because the initial design of the power supply is to protect the power supply and other components in the chassis when there is leakage, as long as the components in the chassis will not burn out the components when there is leakage, the computer will automatically detect the leakage phenomenon and give an alarm.

The chassis is not leakage, but the chassis is metal, so it will be dotted, and the power supply of the computer chassis is a three-hole socket, take the socket apart, connect the socket hole of the three-hole socket with a wire, and connect the other end to the ground, so that the chassis will not exist with a point.

Get the repair shop to repair the computer can be repaired, it doesn't cost a lot of money, it may be caused by the aging of the circuit, or the contact is poor, in short, the problem is not big.

This is normal! A lot of computers have this problem! The leakage is only static electricity, which does not affect the use, and it is best not to repair it!! It's all invisible.

If your hands are wet, the machine will be electrified, which is normal.

Regarding power failure, first check your CPU heat dissipation, whether the fan is rotating, whether there is too much ash, power loss is generally a protective phenomenon caused by heat dissipation.

One end of the wire is connected to the chassis, and the other end is grounded (the ground can be the heating pipe at home, as long as it can communicate with the earth), so that the electricity will be imported into the earth, and there will be no more electricity.

If there is a condition, the ground wire in the power socket can be grounded, so that it is all done, and there is no need to use the wire to connect the computer chassis and the ground, I hope to solve it as soon as possible!!

It may be that some of the wiring of your computer is loose, and the wire and the shell are short-circuited, so that there is electricity, but it is necessary to distinguish whether it is generated electricity or induced electricity, if it is induction, it may be caused by the dampness of your computer or the leakage of some components. Induced electricity does not harm people.

Do you have a grounding wire at home, you generally need a grounding wire, if there is no grounding wire, it may leak.

Since it's a new computer, looking for after-sales service, you can't joke with your life.

Also, how do you know that the computer is leaking electricity and the keyboard is plastic?

Although the power supply is leaking, it is useless to change the power supply, because the circuit structure inside the power supply determines that if there is no ground wire, it must leak (if you want to know what the principle is, you can continue to ask.) The leakage voltage is about 110V or less), the effect of connecting to the anti-theft net is not necessarily good, because the anti-theft net is not directly grounded, so the grounding resistance of such grounding is large, and it is still possible to leak. The formal way to connect the ground wire is to use a steel bar to drive about one meter into the ground, and then connect the ground wire to this steel bar.

When there is leakage, do not touch any parts on the motherboard with your hands, because although the current is very small and safe for people, it is different for the motherboard, and the high voltage will burn the motherboard instantly.

The computer case shell is not accurately grounded, and the live shell will not only cause people to be electrocuted, but also cause other faults if the current is conducted to the motherboard, so it is recommended to do a good job of grounding the equipment.

Leakage is naturally due to the poor insulation of the power supply or motherboard in the case, which causes the case to be dotted, which will not burn things, but will power you.

Chassis leakage generally means that the chassis shell and phase wire insulation is not good Generally, if it is a three-wire plug with protective grounding, the leakage of electricity on the chassis is shorted to the protective ground wire There will be no potential safety hazards If the protective ground wire is not connected, it will be electrified, as for the hardware, it will generally not burn out.

Generally speaking, it is the case power supply that is connected to the chassis that leaks!

The main cause of case leakage is that there is a problem with the power supply of the case, which may be that some parts are damaged.

Another cause of leakage in the chassis is that the chassis is not connected to a three-wire plug. The three-wire plug can connect the ground wire in the chassis power supply to the ground line in the grid (home) to avoid leakage.

Under normal circumstances, leakage of the chassis will not damage the hardware, unless the voltage is large and the wires are directly in contact with the motherboard and other hardware. However, if there is a leakage, it is recommended to rule it out immediately, and do not have a fluke mentality to avoid the problem from expanding.

Leakage hazard If it's static electricity, it doesn't matter.
