MSI motherboard cmos jumper

The first light on the MSI motherboard is always on

1. It may be due to the following reasons: The monitor connection and the graphics card are not tightly plugged in and re-inserted; the graphics card and motherboard agp The slot is not inserted tightly, and re-inserting and unplugging will still work; the graphics card is broken, and the computer that is running well should disassemble the graphics card and insert it; the motherboard is damaged. The alarm sound when unplugging the memory proves that the motherboard is damaged. Replacing the motherboard solves the problem.

2. The DRAM indicator light is always on, which is a very common problem. This means that the motherboard's memory self-test has not passed, and there is a problem with the memory. Similarly, the monitor will display a no signal prompt and then a black screen. The BOOT indicator light is always on.

3. There may be a power failure. After turning on the computer, check if the red light flashes. If it flashes, unplug the network card, graphics card, memory, etc., cut off the power supply, and wait 3 minutes before installing them again. That's it. If the motherboard is burned, check if the resistor drum on the motherboard is bulging. The bulging means the motherboard is burned.

4. The boot light on the MSI motherboard is always on because there is an error in the connection of the switch key. The startup and restart of the chassis are connected to the computer motherboard with a jumper. You can use a screwdriver to short-circuit the motherboard startup key pins. If the computer can start, it means there is a problem with the startup key. You can also check the graphics card or graphics card slot to see if it is inserted incorrectly and whether there is any problem with the graphics card.

5. As long as you enable memory X.M.P. in the BIOS, this light will be on. By default, it will not be on. it `s just normal.

6. The red light on the motherboard is always on. There may be a problem with the CUP. For example, the BIOS is not compatible with the CPU, or the pins under the CPU are bent, or the contacts underneath are blocked, or the motherboard pin sockets have bent pins, or the CPU power supply is not plugged in properly. You can reinstall the CPU or replace it with another one. try.

Two issues with cmos discharge and keyboard jumper

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.

When COMS is discharged, the basic settings of the computer motherboard bios will return to the factory settings. Keyboard failure caused by cmos power failure is that when COMS is discharged, the basic settings of the computer motherboard bios return to the factory settings.

If the power cord is unplugged, take out the battery for a few seconds and the motherboard will return to factory defaults. Pay attention to the jumper and see if there is COMS printed next to the battery, it has three pins. Connect the jumper cap to position 2. Take out the jumper cap and connect it to position 3. This completes the jumper. Then connect the jumper cap back to position 2.

You can see the model of the battery on the battery. If the battery needs to be replaced, you need to select the same model of battery for replacement, as shown in the figure below, and then proceed to the next step. 5. Finally, after completing the above steps, wait for a while and put the battery back into the battery slot on the motherboard, as shown in the picture below. This clears the CMOS information.

How to set and clear the CMOS jumper on the MSI B85-E45 motherboard? I don’t understand the instruction manual, which two jumpers to use...

1. Turn off the computer host and disconnect the power supply. Remove the chassis side panels. You can find the CLRCMOS jumper next to the BIOS battery on the motherboard. There are three pins in total. Normally, the jumper cap is inserted on the two pins on the left side so that the CMOS information will not be cleared.

2. Method 1: Find the CLRTC jumper, unplug the cmos jumper cap from 12pin, and plug it into 23pin. After that, plug the 12pin back in, as shown in the picture below; Method 2 removes the motherboard button battery, reinstall it for about 5 seconds, and finally install the battery normally, as shown in the picture above.

3. 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 "2". Connect them on the "3" pin. From the discharge instructions, you can know that the state is "Clear CMOS", that is, clear CMOS (as shown in the figure below).

4. The following picture is an example: The position of CLRTC of PRIME Z390-A is marked 13. Note: This is a schematic diagram. Please refer to the motherboard for the actual position. CLRTC: a. Turn off the computer power and unplug the power cord.
