Really, the DP signal cable does not support hot swapping! When I unplugged the DP cable, I burned all the computer motherboards!

<h1>DP signal cable can also burn out the motherboard? That's why! </h1>

Recently, I saw a netizen share an amazing experience - he unplugged the DP signal cable in a live state, and as a result, the computer motherboard, memory and hard disk were all burned out! This makes many people think it is incredible, what is the reason for this?

It turned out that the root cause of this serious consequence was that there was a problem with the wiring of the power supply line of the house. Carefully analyzing the descriptions of netizens, we can find the crux of this problem:

<h2>零线和地线接反</h2>

Generally speaking, the correct power supply socket should be the left-side, zero-right, and middle-ground fire. However, when some houses are being renovated, the electrician may have some problems with the connection between the neutral wire and the ground wire, such as connecting the neutral wire and the ground wire in reverse. This may seem like a small mistake, but it can have serious consequences.

In this case, the housing of the electrical equipment will become electrified, and once it comes into contact with other grounding equipment, a current path will be formed, which will cause the equipment to burn out instantly. In other words, when the user unplugs and unplugs the DP signal cable in the live state, the current of the host shell will be instantly discharged through the signal line, which will burn out the core components such as the motherboard and memory.

<h2>防范措施很简单</h2>

Solving this problem is also very simple, just check that the power socket in your home is wired correctly. If you find that the neutral wire and the ground wire are reversed, you can find a professional electrician to readjust it.

In addition, when we use computers and other equipment in daily life, we should also develop good usage habits, and then wiring and unplugging operations in the state of power failure, so as to greatly reduce the risk of accidents. After all, once the motherboard is burned out, it is not only troublesome to repair, but also costly.

Therefore, when using electronic equipment, we must pay attention to the safety of the power supply line and maintain good usage habits, so as to protect the equipment and protect our own safety. After all, electricity is a double-edged sword, and only if we use it carefully and cautiously will it become an indispensable helper in our lives.

Moving on, what happened to this netizen not only makes us realize the importance of power supply line safety, but also makes us reflect on our usual habits of using electronic devices.

In their daily lives, many people will habitually plug and unplug various data cables and power cables in the power-on state. But this method of operation has proven to be unsafe, and it can ruin expensive electronic equipment if you are not careful.

Think about it carefully, in our daily life, we generally shut down first and then plug and unplug U disks, hard disks and other peripherals, why not do this for DP, HDMI and other video cables? Many people may think that this kind of signal line will not cause much trouble, but this is not the case.

As previously analyzed, even if the computer host and monitor do not have grounding problems, plugging and unplugging the signal cable in a live state may burn out the motherboard due to instantaneous discharge. Therefore, when we handle any electronic equipment, we should develop a good habit of shutting down before operating, which can not only protect the equipment, but also ensure our own safety.

In addition, when we usually buy power sockets, we should also pay attention to see whether they meet the national standards and have grounding protection functions. Only by ensuring that the electrical wiring in our home is correct and the equipment is well grounded, can we use electronic products with confidence and avoid similar accidents.

In conclusion, this case tells us that electricity safety is by no means a trivial issue, it is related to the property and life safety of everyone in our daily lives. As ordinary consumers, we must not only learn to use electronic devices correctly, but also always pay attention to the safety of the power supply lines at home, only in this way can we truly enjoy the convenience brought by technology, instead of suffering irreparable losses.
