If there are operational errors such as inability to power on, black screen during power on, or automatic restart due to LVDS settings on the motherboard, it can be resolved by reinserting internal components or plugs. If hardware plugging and unplugging do not work, you can also try resetting the motherboard BIOS to its factory settings (commonly known as discharging the motherboard)

I have compiled three methods for discharging motherboards, and you can use one or more of them simultaneously according to your situation

Method 1 for discharging the motherboard: Use BIOS discharge jumper

For most motherboards, BIOS discharge jumpers are designed to facilitate user discharge operations, which is the most commonly used BIOS discharge method. The discharge jumper is generally three pin (there are also two pin ones), located near the BIOS battery socket on the motherboard. There will be JBAT or CLRTC next to the jumper socket. Taking the three pin jumper as an example, in the default state of the motherboard, the jumper cap will be connected to the pins marked as "1" and "2". From the discharge instructions, it can be known that it is "Normal", which means it is in normal use. To use this jumper to discharge, first use tweezers or other tools to remove the jumper cap from the pins "1" and "2", and then attach it to the pins labeled "2" and "3" to connect them together. The discharge instructions indicate that the current status is "Clear BIOS", which means clearing the BIOS. After a brief contact, various manual settings of the user in the BIOS can be cleared and restored to the default settings of the motherboard at the factory

After discharging the BIOS, it is necessary to remove the jumper cap from the "2" and "3" pins and restore it to the original "1" and "2" pins. Note that if the jumper cap is not restored to the Normal state, the computer cannot be started and there will be an alarm sound prompt.

Note: For a two pin jumper, simply short-circuit the two pins with a metal object for about 10 seconds to complete the discharge operation on the motherboard.

Motherboard discharge method 2: Remove the motherboard battery

What should I do if I discharge the BIOS on the motherboard but cannot find the jumper for BIOS discharge on the motherboard? At this point, the BIOS can be powered by the battery to achieve the purpose of discharging. Because the power supply to the BIOS is provided by the BIOS battery, removing the battery can cut off the power supply to the BIOS, thus clearing the parameters set by the BIOS itself

Find the BIOS battery socket on the motherboard, the circular one is the motherboard battery,

Next, press the clip on the socket that holds the power battery to one side. At this point, the BIOS battery will automatically pop out. Carefully remove the battery (the two metal objects on the base are the positive and negative poles)

Then turn on the host power and start the computer. The screen will prompt that the data in the BIOS has been cleared and needs to be reset by entering the BIOS. This proves that the BIOS has been successfully discharged.

Method 3 for discharging the motherboard: Short circuit the positive and negative terminals of the battery socket to discharge the motherboard

The method of removing the power supply battery to discharge the BIOS has a certain success rate, but it is not omnipotent. For some motherboards, even if the power supply battery is removed for a long time, it cannot achieve the purpose of discharging the BIOS. In this situation, it is necessary to use the method of short circuiting the positive and negative poles of the battery socket to discharge the BIOS.

The BIOS battery socket is divided into positive and negative poles, which can be short circuited to achieve the purpose of discharging. Firstly, remove the BIOS power battery from the motherboard, and then use conductive materials such as screwdrivers and tweezers to short-circuit the positive and negative terminals of the battery socket, thereby achieving the purpose of BIOS discharge.
