How to discharge the computer motherboard, how to discharge the computer motherboard

Sometimes, the laptop can't be turned on, we may try to re-insert the memory, or discharge the motherboard CMOS battery of the notebook, and reset the BIOS, but the memory re-insertion is very simple, but for the motherboard CMOS battery discharge of the notebook, many netizens do not know how to operate. So how do you discharge the CMOS battery of a laptop motherboard? Let's share it with the installation house.

We all know that the motherboard of a desktop is very convenient to discharge, just open the side panel of the case and remove the round button cell battery on the motherboard.

Take it off, wait for 5 minutes, preferably 10 minutes (the time is not fixed, in fact, 10 seconds is generally good, of course, if it doesn't work, you can try to take a longer time), and then install the battery back to complete a discharge, BIOS reset.

If you want to turn off the notebook, you need to disassemble the bottom panel of the notebook (D-side), because different models of notebooks are a little different to disassemble, so I won't demonstrate it, it is nothing more than to remove the screws of the bottom panel (D-side) of the notebook, and remove the bottom panel (D-side), you can see the motherboard, but some notebooks still can't remove the screws on the D-side after disassembling them, the reason is that because there are clips, you need to warp the edges.

After the D side of the notebook is disassembled, we can see the motherboard, and next to the motherboard there is a round thing wrapped in plastic, which is the button battery.

Remove it at the connection interface of the button, which is usually plug-in.

After the interface is removed, wait for 5 minutes, preferably ten minutes (the time is not fixed, in fact, 10 seconds is generally good, of course, if it doesn't work, you can try to take a longer time), and then plug the interface back to complete the discharge of the CMOS battery of the motherboard of the notebook, and reset the BIOS.

If you don't know how to discharge the CMOS battery of the notebook, you may wish to solve it through the above methods, in fact, it is similar to the desktop method, but the button battery connection method is different.

1. First of all, unplug the power supply of the chassis and disassemble the side cover.

2. Find the motherboard battery, which is generally a little below the graphics card slot, and some people's chassis batteries are blocked by the entire graphics card, so you have to remove the graphics card first.

3. Press and hold the small metal clip inside and take out the battery.

4. Then use a screwdriver to touch the metal sheet under the battery and the metal clip just held down the battery at the same time. If you don't have a screwdriver, remove the battery and press the power button.

5. Find the front and back of the battery (positive and negative poles) and put it back on. If you can't tell the difference between the front and back, take a picture with your mobile phone before dismantling.

Restore BIOS, release static electricity, tips.

Use a CMOS discharge jumper.

To use this jumper to discharge, first pull the jumper cap out of the pins "1" and "2" with tweezers or other tools, and then attach them to the pins identified "2" and "3".

From the discharge description, it can be seen that the status is "clear CMOS", that is, the CMOS is cleared. After a short period of contact, the user's manual settings in the BIOS can be erased and the motherboard can be restored to the default settings when the motherboard left the factory.

Waterproof water is the most direct killer of laptops, but there will be many people who tend to ignore a lot of potential "water". As you know, the motherboard of a notebook is much more integrated than that of a desktop due to its small size, which leads to a relatively high production cost.

If an accident occurs on the motherboard, the cost of replacing the motherboard generally accounts for about one-third of the whole machine, because this kind of accident is generally a man-made fault and is not included in the warranty, so the repair cost can be said to be jaw-dropping.

The method of discharging the computer motherboard is as follows:

1. Turn off the power of the computer.

2. Open the computer case and find the button cell battery on the computer motherboard.

3. There is a fixed battery tenon on the CMOS battery base of the motherboard.

4. Press the tenon outward with a screwdriver or directly by hand.

5. At this time, the CMOS battery will pop out, take it out with your right hand to complete a "discharge", and then place the CMOS battery in its original position.

Computer (computer), commonly known as computer, is a modern electronic computer used for high-speed calculation, which can perform numerical calculations, logical calculations, and also has the function of storage and memory. It is a modern intelligent electronic device that can operate according to the program and process massive amounts of data automatically and at high speed. A computer that consists of a hardware system and a software system without any software installed is called bare metal.

It can be divided into five categories: supercomputers, industrial control computers, network computers, personal computers, and embedded computers, and the more advanced computers include biological computers, photonic computers, quantum computers, etc.

Inventor of the computer John von Neumann. The computer is one of the most advanced scientific and technological inventions of the 20th century, which has had an extremely important impact on human production and social activities, and has developed rapidly with strong vitality. Its application field has expanded from the initial military scientific research application to all fields of society, and has formed a huge computer industry, which has led to technological progress on a global scale, which has triggered profound social changes, and computers have spread all over ordinary schools, enterprises, and institutions, and have entered the homes of ordinary people, becoming an indispensable tool in the information society.

If the computer motherboard is discharged, you can just hold an iron and put it on the metal to touch it, or take off the battery on the computer motherboard and put it on.

Restore BIOS, release static electricity, tips.

You can remove the coin cell battery (CMOS battery) of the motherboard when the computer is turned off, and then put it back to complete a discharge. The steps are as follows:

1. Turn off the power of the computer.

2. Open the computer case and find the button cell battery on the motherboard of the computer, as shown in the figure below.

3. There is a tenon on the CMOS battery holder of the motherboard to fix the battery, as shown in the figure below.

4. Use a screwdriver or directly press the tenon outward, as shown in the figure below.

5. At this time, the CMOS battery will be ejected, and a "discharge" can be completed by taking it out by hand, and then the CMOS battery will be placed in place.

What can be avoided and improved is as follows:

1. Turn off the external power first, and press the start button and the reset button (restart button) alternately for 2-3 seconds each time, and press about 5 times each time. Clean up static electricity;

2. Pay attention to cutting off the external power supply every time you shut down in the future, and it will generally not appear in the future;

3. In addition, pay attention to the metal solder joints at the bottom of the motherboard, it is very likely that there is a problem of contacting the chassis, remove the motherboard to see if there is a longer one, and see if the chassis has a place where the paint is worn off. It is recommended to go to the installation point to find an anti-static bag for motherboard packaging, pad it under the motherboard, and insulate it.

Computer chassis motherboard, also known as motherboard, systemboard or motherboard; It is divided into two types: commercial motherboards and industrial motherboards.

It is installed in the chassis and is one of the most basic and important components of the microcomputer. The motherboard is generally a rectangular circuit board, on which the main circuit system of the computer is installed, generally there are BIOS chips, IO control chips, key and panel control switch interfaces, indicator plugs, expansion slots, DC power supply connectors of the motherboard and plug-in cards and other components.

How to discharge the computer motherboard:

1. Use the CMOS discharge jumper to use the jumper to release the key or send power. Use tweezers or other tools to pull out the jumper cap from the pins of "1" and "2", and then put it on the pins marked as "2" and "3" to connect them, after a short contact, you can clear the user's various manual settings in the BIOS, and restore to the default settings of the motherboard when it leaves the factoryAfter discharging the CMOS, you need to take out the jumper cap from the pins of "2" and "3" and restore it to the original pins of "1" and "2".

2. Take out the COMS battery and discharge it Find the CMOS battery socket on the motherboard, and then press the buckle on the socket to hold the power supply battery to which side of the group, at this time the CMOS battery will automatically pop out, and take out the battery carefully.

3. Turn on the host power and start the computer, the screen will prompt that the data in the BIOS has been cleared, and you need to enter the BIOS to reset it. This proves that the CMOS has been successfully discharged.

If you take off the battery (coin cell) on the motherboard, most of the time will be restored to the factory settings, and the length of time is mainly determined by the string size of the motherboard battery accessory. The settings of the BIOS are maintained by the battery, and after some time after the battery is unplugged, the charge is depleted and the factory is restored.

Generally, there will be a special discharge jumper on the motherboard, or after the battery is removed, the positive and negative poles of the battery socket can be shorted for a few seconds, which can quickly achieve the purpose of discharge.

The computer motherboard is discharged, mainly to remove the twist button battery on the motherboard, and after a few minutes, put it back on the motherboard, which is discharge.

The computer is to deduct the battery of the motherboard, and then press the power button to complete the release of static electricity in the power-off state, which is best not to operate without power.
