When the dell computer is turned on, it rings twice, and it rings again after a period of time, what

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 is long, it may be that the memory module is not plugged in tightly.

2. If the sound is fast and short twice (such as drip, drip): it may be that the CMOS is set incorrectly and needs to be reset, this situation occurs the most, and the English prompt "CMOS checksum failure" will appear at the bottom of the screen (usually at the bottom left), 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. Good luck!

The memory module is loose and re-plugged and unplugged.

First of all, you need to take out the memory module of the computer, wipe the dust or dirt on the gold finger with an eraser or facial tissue, and then insert the memory module into the memory module slot. Note that the direction cannot be reversed when wiping, and after plugging in, it must be fastened.

If not, you need to buckle the electronics on the motherboard, unplug the computer power, connect the positive and negative poles in the electronic buckle slot with wires for ten seconds, remove the wires, and then install the electronics, and then plug in the power supply, and then it should be able to turn on.

After booting up, you can enter the computer's operating system normally.

Hello, the fault sound emitted by the system motherboard needs to be determined by which manufacturer's BIOS the motherboard is using. If you are using:

1) The BIOS of the AMI has two ticks, no interval, and then pauses, and then two ticks, indicating that when the system boots up to detect the memory, the parity check of the first 64K of the memory fails to pass, and the memory module needs to be replaced;

2) The BIOS of the award, two beeps and drops, no interval, and then pauses, in two beeps, it means that there is a problem with the system's CMOS detection, and this needs to replace the CMOS chip, so it is a problem with the motherboard, and the motherboard needs to be replaced, or try to remove the button cell battery on the motherboard, and then put it back after a while, to see if the CMOS data will be reset. If not, you'll need to replace the motherboard.

3) BIOS of the award, 1 sound length drop followed by 1 sound segment drop, pause after that, and then repeat 1 sound length and 1 sound segment, indicating that there is a problem with the memory module and the memory module needs to be replaced;

If you replace the memory module or there are two beeps when you turn on the phone, then you need to replace the motherboard, and you need to take it to Dell's after-sales department for repair.

The hardware device is broken.

Which one is specific, you have to find a professional person to test.

Different rings.

The length is not the same.

But it's a hardware device for sure.

It should be that the system detects a fault alarm, and it may be that the motherboard, power supply, graphics card, or BIOS cannot pass.

1. Desktops generally install a buzzer on the motherboard to provide an error report function in the boot self-test.

2. If the system can be turned on normally but there is a sound, it is generally a prompt sound that informs the user that the normal self-test procedure has been carried out, and does not need to pay attention to it. It is also possible that the system can boot up, but there is a problem with some hardware.

3. If the computer cannot be turned on, please search the network according to the number and length of the alarm sound, and then you can check the corresponding hardware problems. If you don't want to hear the dripping sound, you can turn it off or disassemble it in the BIOS and unplug the buzzer.

The laptop rings five times at a time, which indicates a real-time clock failure.

How to deal with the real-time clock failure of the notebook and the alarm and the five rings:

1. Generally, this phenomenon is encountered, which means that the laptop motherboard battery is out of power, when the motherboard battery is low, resulting in the coms random memory can not save the data, so that the time and date can not be saved, and the alarm sound is caused.

Solution: Just replace the motherboard button battery.

2. It is the failure of the resonant circuit, such as the resonant capacitor, 106 resistance, and the failure of the real crystal oscillator, resulting in the inability to save the data, the time and date cannot be saved, and the alarm sound.

Solution: Send the after-sales service to repair the motherboard in time, or send the notebook repair point to repair the components of the resonant circuit.

(1) Dell laptop turns on five times at a time, which means that there is a real-time clock failure.

2) How to deal with the real-time clock failure of the Dell notebook and the alarm and the five rings:

1) Generally encounter this phenomenon, this is on behalf of the notebook motherboard battery is out of power, when the motherboard battery is low, and the lead to the coms random memory can not save the data, so that the time and date can not be saved, and the alarm sound, the solution: is to replace the motherboard twist battery.

2) It is the failure of the resonant circuit, such as the resonant capacitor, 106 resistance, when the real crystal oscillator fails, and the data can not be saved, the time and date can not be saved, and the alarm sound, the treatment method: timely send the after-sales repair motherboard, or send the notebook maintenance point to repair the components of the resonant circuit.

Normal, don't think about it, it's all screensavers.

There is a problem with the sound card, maybe the card strip is dirty or loose.
