Operation errors such as setting LVDS on the motherboard and causing the computer to fail to turn on, turn on to a black screen, or automatically restart, can be solved by re-inserting internal accessories or plugs. If plugging and unplugging the hardware doesn't work, you can finally try restoring the motherboard BIOS to factory settings (commonly known as discharging the motherboard).
Three methods for motherboard discharge have been sorted out. You can use one or several of them at the same time according to the situation.
Method 1 to discharge the motherboard: Use the BIOS discharge jumper
Most motherboards are designed with a BIOS discharge jumper to facilitate user discharge operations. This is the most commonly used BIOS discharge method. The discharge jumper is generally three-pin (there are also two-pin) and is located near the BIOS battery socket on the motherboard. There will be JBAT or CLRTC next to the jumper seat. Taking the three-pin jumper as an example, in the default state of the motherboard, it will jump The wire cap is 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 the jumper cap off the pins "1" and "2", then place it on the pins labeled "2" and "3" and remove them. After connecting it, we can know from the discharge instructions that the status is "Clear BIOS", that is, clearing the BIOS. After a short period of contact, the user's various manual settings in the BIOS can be cleared and restored to the motherboard's factory default settings.
After discharging the BIOS, you need to remove the jumper cap from the "2" and "3" pins, and then 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 an alarm will sound.
Note: For a two-pin jumper, you only need to use a metal object to short-circuit the two pins and wait for about 10 seconds to complete the discharge operation of the motherboard.
Motherboard discharge method 2: Remove the motherboard battery
Discharge the motherboard bios, but the bios discharge jumper cannot be found on the motherboard. What should I do? At this time, the bios can be powered by the battery to achieve the purpose of discharge. Because the power supply to the BIOS is supplied by the BIOS battery, the power supply to the BIOS can be cut off by removing the battery, and the parameters set in the BIOS will be cleared.
Find the BIOS battery socket on the motherboard. The round one is the motherboard battery.
Then press the buckle on the socket to hold the power battery to one side. At this time, the BIOS battery will pop up automatically. Take out the battery carefully (the two metal objects on the base are the positive and negative poles)
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, you can prove that the BIOS has been successfully discharged.
Method three to discharge the motherboard: Short-circuit the positive and negative terminals of the battery socket to discharge the motherboard
Although the method of removing the power supply battery to discharge the BIOS 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 discharging the BIOS 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 bios.
The BIOS battery socket is divided into positive and negative poles, and short-circuiting them can achieve the purpose of discharge. First, remove the BIOS power battery from the motherboard, and then use conductive items (screwdrivers, tweezers, etc.) to short-circuit the positive and negative terminals on the battery socket to cause a short circuit, thus achieving the purpose of discharging the BIOS.
