How to discharge laptop motherboard battery?

Laptop motherboard battery discharge is an effective way to solve certain problems (such as the computer not working properly, no response when starting up, etc.). PHP editor Strawberry will introduce in detail the steps to discharge the motherboard battery to help everyone solve these problems. Read on to learn how to discharge your laptop motherboard battery safely and efficiently.

How to discharge the laptop motherboard battery?

Unplug the battery The most direct way is of course to unplug the battery. In this case, because there is no power supply, the motherboard will lose its cache and real-time clock functions. Tip: There is usually a clip above the battery on the computer motherboard. Open it to remove the battery.

2.

Use software to discharge. If you are afraid that removing the battery will cause damage to your computer, then you may consider using software to discharge. For example, if your computer has the operating system Windows 10, you can open the command prompt and enter the following command: powershell "Invoke-WmiMethod –Class Win32_Battery –Name BatteryDischarge –ArgumentList 0" This will start the discharge program and you only need to wait for the program That's it. Please note, make sure your computer is connected to a power source when using this method. Otherwise, you will not be able to complete the discharge and may damage your computer.

3.

Using peripherals Using peripherals is another way to discharge the battery.

How to discharge the laptop motherboard?

There are two ways to discharge the notebook motherboard:

One is to remove the battery and power cord, and then press and hold the power button for more than 10 seconds to release all the charge;

The other is to use a professional discharge tool, connect the tool to the discharge interface on the notebook motherboard, and then operate according to the tool instructions. The purpose of discharge is to remove static electricity from the motherboard, prevent static electricity from damaging electronic components, and also solve some computer malfunction problems. When performing discharge operations, be sure to pay attention to safety to avoid electric shock or damage to the computer.

How to discharge the motherboard battery in a laptop? Is there any method?

There are many ways to discharge the laptop motherboard battery. Commonly used methods include:

1. Shut down the laptop and disconnect the power supply, then press and hold the power button for 10-15 seconds to Make sure the motherboard battery is completely discharged;

2. Disassemble the laptop, find the spare battery on the motherboard, and short-circuit the 2 contacts with metal wires until the voltage is 0V;

3. Use Professional discharge tools, such as motherboard battery dischargers, operate according to the instructions. Regardless of the method used, caution is required to ensure your own safety and avoid damage to your equipment.

What does discharge of laptop motherboard mean?

Discharge means there is a battery on the computer motherboard, which records the bios settings. If you remove the battery, the computer bios will return to the default values. Just install the battery again after a few minutes.

How to discharge the laptop motherboard?

In fact, it is very easy to discharge the motherboard battery. Just remove the button battery (CMOS battery) from the motherboard when the computer is turned off, and then put it back to complete a discharge.

First we open the computer case and find the button battery on the motherboard of the computer.

There is a latch on the CMOS battery holder of the motherboard that fixes the battery.

We can Use a screwdriver or just use your hands to push out the tenon.

The CMOS battery will pop out. We can take it out by hand to complete a "discharge", and then put the CMOS battery in its original position.

How to discharge the laptop motherboard?

1. Use CMOS discharge jumper

Most current motherboards are designed with CMOS discharge jumpers to facilitate users to perform discharge operations. This is the most commonly used CMOS discharge method. . The discharge jumper is generally three-pin, located near the CMOS battery socket on the motherboard, and comes with battery discharge instructions. In the default state of the motherboard, the jumper cap will be connected to the pins marked "1" and "2". From the discharge instructions, we can know that it is "Normal", which is the normal use state.

To use this jumper to discharge, first use tweezers or other tools to pull out the jumper cap from the pins "1" and "2", and then put it on the pins marked "2" and "3" "Connect them on the pins. From the discharge instructions, we can know that the state is "Clear CMOS" at this time, that is, clear CMOS.

2. Take out the CMOS battery

You can use the CMOS power supply battery to achieve the purpose of discharge. Because the BIOS is powered by a CMOS battery, removing the battery can cut off the BIOS power supply and clear the self-set parameters in the BIOS.

Find the CMOS battery socket on the motherboard, and then press the buckle on the socket to hold the power supply battery to one side. At this time, the CMOS battery will pop up automatically. Take out the battery carefully.

Then turn on the power of the host 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. In this way, it can be proved that the CMOS has been successfully discharged

3. Short-circuit the positive and negative terminals of the battery socket

Although the method of removing the power supply battery to discharge the CMOS has a certain success rate, it is not a panacea. For some motherboards, even if the power supply battery is taken out for a long time, the purpose of CMOS discharge cannot be achieved. In this case, you need to use the method of short-circuiting the positive and negative terminals of the battery socket to discharge the CMOS. Of course, on motherboards with CMOS discharge jumpers, if you think the CMOS discharge operation is too troublesome, you can also use this method.

The CMOS battery socket is divided into positive and negative poles, and short-circuiting them can achieve the purpose of discharge. First, take out the CMOS power supply battery on the motherboard, and then use conductive items (screwdrivers, tweezers and other conductive items) to short-circuit the positive and negative poles on the battery socket to cause a short circuit (as shown in the figure below), thereby achieving CMOS The purpose of discharge.
