How can my laptop whine as soon as it is turned on, like an alarm

First of all, you have to tell us in detail, where did this "woo" call come from, is it the heat dissipation port? Or speakers? Or somewhere else? This makes it easier for us to judge.

If it is a speaker, it may be that the keyboard is stuck, or it may be that the memory module or hard disk interface is loose.

It's very simple,Your sound method must have something to do with the fan,Because it has affected the boot,I believe that just a simple dust removal can only reduce the sound at most,But it has little impact on the problem you want to deal with,It proves that it has nothing to do with the hard disk,Can't shut down this can also be concluded to be a fan problem,It is recommended that you go to the after-sales center for maintenance。 If you insist on using it and forcibly shut it down, the machine will soon be scrapped.

Can't you use a mouse with a touchpad that comes with it? Did you get into the water? You have to take it to repair, and if you can dismantle it yourself, it's best to check the problem yourself.

The fan is ringing, take it to clean up the dust, and uninstall the boot startup item!

It is generally fine to disassemble the back cover of the computer, remove the memory module, wipe it with an electrostatic cloth, or replace it with toilet paper, and then plug it back in. If it's not good, the board burns.

It's either a fan problem or a hard drive problem! It is recommended to go to a professional maintenance place to consult!

There is too much dust in the fan, and it will be much quieter to remove the dust.

If you don't know the situation, take it for repair! This seems to be a bit serious!

I'm telling you, it's your sound card driver that is corrupted, and it's done from scratch to install the system.

Is it out of power [the kind that is not plugged in = =.]

A hardware error is reported. What is the specific alarm sound? How short and how long?

Reason 1: There are many reasons why the fan is loud, and we need to eliminate it step by step. Let's start with the software.

If the high temperature continues, then it may be that there are a large number of programs running in the background of the computer, resulting in the high heat generation of the CPU running at high speed, and the fan must be maintained at a large wind speed to achieve the purpose of heat dissipation. Reason 2: The cooling fan is damaged, the fan will gradually wear out after a long period of use, or due to the lack of oil in the bearing, it will make the fan produce a loud sound when it rotates.

Moreover, due to the low degree of fineness of workmanship, the center of gravity of the fan blades will deviate from the center of gravity of the fan blade, which will cause the fan to be abnormal.

Continue to despise Lan Youzhi Report you as a pig policeman, he said that the stereo was chirping.

The microphone is broken!

Take the memory to other computers and try it, and use the memory of other computers to try to listen to the sound, and judge the failure:

An alarm occurs when a problem is found during BIOS POST.

When the computer has a boot failure, it will emit different chirps to indicate the location of the fault (there are two types according to the motherboard).

The meaning of the award motherboard alarm sound.

1. Short: The system starts up normally.

2 Short General Error, Please Go to CMOS Setup to Reset Incorrect Option 1 Long 1 Short RAM or Motherboard Error.

1 long 2 short display error (monitor or graphics card).

1 long 3 short keyboard controller error.

1. Long, 9 short: Motherboard, Flash, RAM, or EPROM Error (BIOS Corruption), Constant Ringing (Long Noise), Unstable or Corrupted Memory.

The power supply keeps ringing, and the monitor is not properly connected to the graphics card.

Repeat the short ring of the power supply.

No sound, no display power.

1. Short: Memory flush failed.

2. Short memory ECC verification error.

3 Short System Basic Memory (1st 64k) Check Failed 4 Short System Clock Error.

5 Short **Processor (CPU) error.

6 Short Keyboard controller error.

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

8 Short: Shows a memory error (shows that the memory may be broken).

9. Short ROM BIOS verification error.

10 short CMOS shutdown register read write error.

11. Short cache memory error.

1 long 3 short memory error (memory corruption, please replace).

1. Long 8 short display test error (the display data cable is loose or the display card is unstable).

Hello dear, 1. Fan sound: This is obvious, you will hear it when you turn it on, open the cover with some oil, and clean up the dust;

2. Hard disk ringing: When you open a file, open a game or copy a file, the most obvious sound, "zizizi" sound, this means that the hard disk may be broken, there is no way to deal with it, but you can open the hard disk cover to check whether the screws that fix the hard disk are loose;

3. Electric current: This is rare, generally accompanied by a scorching smell, if this is the case, take it to repair it quickly.

What about re-driving the sound card driver??? Let's see if you can cancel the echo in the sound card software. Troubleshoot the software problem first, if it can't be solved, the microphone is broken.

If you can still turn on the computer and enter the system, then check if one of the keyboard buttons is stuck!!

If you can't turn on the machine and can't enter the system, it should be a hardware failure!

It should be a hardware failure, the BIOS will automatically detect the settings of the computer hardware when the computer is turned on, and if the fault is found, an alarm sound will be issued, and the meaning of the alarm sound is shown in the reference materials.

If you have a problem with the microphone, or if you have a problem with the microphone jack, try a different microphone.

In this case, it is directly related to the hardware, and it is recommended that you perform the following operations:

1. Remove the battery on the back of the notebook, connect the computer with only the power adapter, and try to turn on the computer, if the boot is normal, then it is caused by poor battery contact or battery failure.

2. Only use the battery, do not connect the power adapter, if the boot is normal, then it should be caused by a problem with the power adapter or a short circuit in the power interface of the notebook.

3. Unplug the power cord, remove the battery, and press and hold the power button for 30 seconds without letting go. Try to boot up, if the boot is normal, then it is only caused by the abnormal BIOS of the motherboard.

4. Unplug the power cord, remove the battery, open the back cover of the memory, plug in and unplug the memory, wipe the gold finger part with an eraser, and plug it back in (don't reverse it).

5. If the above operations cannot solve the problem, it is recommended that the notebook be sent to the maintenance center for testing.

As the CPU occupancy changes, the temperature will rise, and the fan will automatically adjust the speed, and when the temperature is too high, it will accelerate the rotation. That's what makes the sound. When the temperature drops, the rotational speed is reduced or even stopped.

Then it detects a temperature rise and automatically turns on the fan. All with intermittent whining. It's normal.

Don't worry.

1. The disc is not taken out, when it is turned on, the disc starts to run, there is a whining sound, and it will also make a whining sound when it is turned on.

2. The machine is rusty, and some parts are rusty, which makes it difficult for some parts to run when the machine is just running.

3. Some parts are sticky with dust, if you don't clean it, the dust will accumulate more and more in the host, and finally the parts will not run.

4. When the computer is turned on, the hard disk will make this sound when it is told to rotate, and the optional fan will make this sound.

Check on the Internet whether the same model has a similar problem, this should be a normal phenomenon, try to use four bottle caps to pad the four corners of the notebook, pay attention to dusting.

That's the sound of a fan, you can hear it when it's spinning fast, it's normal.
