What s going on with the boot motherboard, one long and three short?

One long and three short is the error of the graphics card, it is recommended that you unplug the graphics card and erase the gold finger of the graphics card with an eraser, and then blow the graphics card slot with a leather tiger, and insert the graphics card back into its original position.

Most of this is caused by static electricity; You can also try unplugging the case, press and hold the power button for a few seconds to release the static electricity in the case, this is relatively simple and should solve the problem;

You can also make a ground wire on the case to release static electricity from the case.

One long and three short is the graphics card failure alarm.

Poor quality of memory slots Poor contact due to thermal expansion and contraction or gravity problems.

Change the socket or change the motherboard.

Generally, the graphics card is loose. For details, please refer to the motherboard manual, which is all on it.

One long and three short is the graphics card failure alarm.

You can clear the CMOS first, and if your computer has been useless, you can turn it on a little longer when the machine is turned on for a while.

You can also unplug the memory and try it.

Depending on the brand of BIOS, one long and three short represent different errors. In the award BIOS, one long and three short is a keyboard controller error; The AMI is represented as a memory error in the BIOS. You can check them all, and try to replace the slots in the memory as well.

In addition, it is also possible that the memory slot can malfunction, such as getting into dust, resulting in poor contact. Therefore, it is recommended that you clean the motherboard thoroughly before checking. Finally, it is recommended that you check the memory

Three short and one long is the BIOS alarm sound of the award. Main workaround: Unplug the memory module, plug it back in, unplug the power cord and plug it back in.

Clean the case dust, wipe the metal part of the memory module back and forth with an eraser, and plug it in. If the first two do not work, it proves that the memory module is damaged and needs to be replaced. <

Demo model: Lenovo Tianyi 510s System version: win10 Take Lenovo Tianyi 510s, win10 system as an example:

One long and three short is the BIOS alarm sound of the award. Main workaround: Unplug the memory module, plug it back in, unplug the power cord and plug it back in.

Clean the case dust, wipe the metal part of the memory module back and forth with an eraser, and plug it in. If the first two do not work, it proves that the memory module is damaged and needs to be replaced.

If the gold finger of the memory module is too dirty, remove the memory module and wipe it clean, the specific operation is as follows:

1. Prepare a screwdriver to remove the back panel of the case.

2. Find the location of the memory module in the picture below in the case and press and hold the white buttons at both ends downward.

3. After taking out the memory module, wipe the gold contact with the motherboard in the picture below with toilet paper.

4. Press down on the memory module gold and install it back on the motherboard.

ASUS motherboards, one long, three short and one short means a RAM refresh error.

1. Unplug the computer power cord first, and press the on/off button on the chassis 5-6 times. Releases the residual charge of the motherboard.

2. Then open the side panel of the chassis and plug and replace the slots of the memory.

3. Remove the CMOS battery from the motherboard and install it after 1 minute.

3. The computer has an independent graphics card, and it is best to plug and unplug the graphics card.

After the above operations are completed, the computer is powered back on.

1 long 3 short sound - Keyboard controller error.

1. 1 short sound - the system starts normally.

2. 2 Short Tone - General Error. The CMOS reset error option should be entered.

3. 1 long and 1 short - RAM or motherboard error.

4. 1 long and 2 short tones - the monitor or graphics card is wrong.

5. 1 long and 3 short - the keyboard controller is wrong.

6. 1 long and 9 short - motherboard flashram or eprom error.

7. Uninterrupted long sound - the memory is not plugged in or the chip is damaged.

8. Non-stop ringing - the monitor is not properly connected to the graphics card.

9. Repeating a short sound - power failure.

10. No sound and no display - no power, or the CMOS battery is drained, or the CPU is wrong.

1. If the sound keeps ringing, it may be that the memory module is not plugged in tightly2. If the sound is fast and short and rings twice (such as drip, drip): it may be that the CMOS setting is wrong and needs to be reset, this situation occurs the most, and the bottom of the screen (generally in the bottom left) will appear in English prompt "CMOS checksum failure", and then ask to press F? （f？

It could be F1 F12, depending on the motherboard) to load the default settings or enter. In addition, this problem may also occur after flashing and updating the BIOS, just load the default settings.

3. If the sound is a long sound and a short sound, it may be a memory or motherboard error.

4. If the sound is one long sound and two short sounds, it may be a monitor or graphics card error.

5. If the sound is one long sound and three short sounds, it may be the keyboard controller error.

6. If the sound is one long sound or nine short sounds, it may be the flash RAM or EPROM error of the motherboard BIOS.

1. If the sound is only a short sound, it may be a memory refresh failure.

2. If the sound is fast and short twice, it may be a memory ECC verification error.

3. If the sound is fast and short twice, it may be that the basic memory check of the system has failed.

4. If the sound is fast and short four times, it may be that the system clock is wrong.

5. If the sound is fast and short five times, it may be that the CPU has an error.

6. If the sound is fast and short six times, it may be a keyboard controller error.

7. If the sound is fast and short seven times, it may be the real mode error of the system.

8. If the sound is fast and short eight times, it may be a memory error.

9. If the sound is fast and short nine times, it may be a BIOS chip inspection error.

10. If the sound is one long sound and three short sounds, it may be a memory error.

After the buzzer is installed correctly, please turn on the device and judge according to the sound emitted by the buzzer. (Please refer to the motherboard manual for the correct position of the speaker).

1.The power indicator lights up and the buzzer responds with a short sound, but there is no screen display.

The buzzer responds to a short sound for normal power, please confirm that the screen is properly connected to the host and the screen is working normally.

2.The power indicator lights up and the buzzer is unresponsive.

Please make sure that your CPU and memory are installed normally and that there is no oxidation in the contacts, if there is an oxidation problem, please try to wipe the oxidized parts with an eraser, if it still does not turn on normally, clean up with a commercially available contact cleaner and reinstall it.

3.The buzzer responds with one long sound and two short sounds.

If the memory is abnormal, make sure that the memory is installed correctly on the motherboard.

4.The buzzer responds with one long sound and three short sounds.

If the VGA needs additional power, make sure that the power supply is sufficient to provide sufficient wattage.

5.The buzzer responds with one long sound and four short sounds.

The CPU fan speed is abnormal, the CPU temperature is abnormal, or the CPU voltage is abnormal.

Please confirm that your CPU or CPU fan is installed correctly. If the exception persists, try clearing the CMOS or updating the BIOS load default

If the above methods cannot be solved, it is recommended to go to the nearest service center for overhaul by an engineer.

The graphics card is loose, check the graphics card!

award bios

1 Short: The system starts normally. Shows that there is nothing wrong with the machine.

2 Short: General error, please go to CMOS Setup and reset the incorrect options.

1 long and 1 short: There is an error in the memory or motherboard. Try to change the memory, if it still doesn't work, you have to change the motherboard.

1 long and 2 short: The display or graphics card is wrong.

1 long and 3 short: The keyboard controller is wrong. Check the motherboard.

1 Long 9 Short: Motherboard Flash RAM or EPROM error, BIOS corruption. Try a different block of flash ram.

Constant ringing (long sound): The memory module is not plugged in tightly or is damaged. Reinsert the memory module, or replace the memory.

ami bios

1 Short: The memory refresh failed. Replace the memory module.

2 Short: The memory ECC verification error is incorrect. Setting the memory option for ECC check to Disabled in CMOS Setup will solve the problem, but the most fundamental solution is to replace a memory.

3 Short: The basic memory check of the system fails. Change memory.

4 Short: The system clock is wrong.

5 Short: There is an error in the CPU.

6 Short: Keyboard controller error.

7 short: The real mode of the system is wrong and cannot be switched to protection mode.

8 Short: A memory error is displayed. If there is a problem with the display memory, try changing the graphics card.

9 Short: BIOS chip check and error.

1 long and 3 short: memory error. If the memory is damaged, it can be replaced.

1 long and 8 short: A test error is displayed. The monitor cable is not plugged in or the graphics card is not plugged in.

(1) Reason: The computer can't be turned on, and there is a three-long and two-short alarm sound, which is likely to be a memory failure, which is due to the formation of an oxide layer on the surface of the memory gold finger, resulting in poor contact between the memory and the memory slot, causing a black screen, alarm, and unable to turn on.

2) Solution: You can turn off the power first, open the compartment, dial out the memory, use the eraser to wipe the part of the gold finger (that is, where there is a copper sheet,) back and forth a few times, and then insert it back into the memory slot (or insert it back into the memory slot), you can install it and restart the computer. (The ** of the memory is as follows:)

If there is a memory problem, reseat the memory.
