Ideacentre B3 Series models have noise during start-up or operation

Failure phenomena:

1. The fan is very loud during startup, normal sound after booting into the system

2. Turn on the fan, the computer does not show any

3. The fan is very loud during the use of the timer

4. The fan in use has been very loud and will not change

5. Sound with high noise and metal friction in use

6. In use the voice is very big, and has the vibration, uses the hand to hold the computer sound to be small

7. Part of the use of similar to boiling water is the cuckoo sound

8. Current sound in use

9. The same type of computer fan sound size is different

Cause Analysis:

The parts of the computer that make sounds are: CPU fan, System fan, Power fan, hard drive, inverter, etc.

Lenovo computer based on the temperature of the computer to control the fan speed, hard disk if in the process of reading and writing sound size is not the same. The function of the inverter is to pay attention to the effect of low pressure to high pressure, using sometimes squeaking current sound.

Solution:

1. The fan is very loud during startup, normal sound after booting into the system

Computer in the beginning of the time, the temperature control function has not been turned on, so some computer boot will appear during the startup process fan sound is very large, when the computer normal startup temperature control function will automatically control the fan speed, this time the computer's voice becomes smaller. This is a normal situation and does not require processing.

2. Turn on the fan, the computer does not show any

If the power on the sound of the fan, accompanied by the computer also does not show, generally for electrostatic reasons or memory failure caused, you can try to unplug the cord, press the host button 5-10 times (press the interval 1 seconds to release, repeated operation), so that the release of static electricity after re-power cord connection, again boot, If still can not solve the need to contact Lenovo after-sales service repair.

3 Computer Use temperature control function, when the component temperature rises, the computer will automatically adjust the fan speed, and so on, the computer will reduce the fan speed, if the computer is not always at a high speed. This is a normal situation and does not require processing.

4. The fan in use has been very loud and will not change

If the fan sound is always in a very large state during use, you will need to check if the individual program has been consuming CPU for a long time, and you can click on the Task Manager by right-clicking on the taskbar.

Check that the CPU usage is high (if the usage exceeds 50% consider whether the system or program is having problems)

If the CPU occupancy rate is 0 or less than 5%, the computer's voice is still very large, this time need to consider whether the accumulation of excessive dust caused the computer cooling bad. This time you need to be able to cause the cooling of the object to move around the computer, put the computer in a ventilated environment to use, if not resolved, you need to contact Lenovo after-sales service repair resolved.

5. Sound with high noise and metal friction in use

If you hear a lot of noise and are accompanied by sound like metal or other objects rubbing, this is usually a fan failure or hard drive failure, if you can not determine the source of sound, please back up your data in a timely manner, contact Lenovo after-sales service.

6. In use the voice is very big, and has the vibration, uses the hand to hold the computer sound to be small.

Computer in the use of the occasional resonance, this general and your computer table has a relationship, if the computer sounds large and accompanied by vibration, please change a table or put the computer on the ground to see if there is still a problem, if normal, you can put on the computer table tablecloth, to the computer and the table in the middle of a certain buffer can be resolved, You can also try to contact Lenovo after-sales service if you change position or place a tablecloth.

7. Part of the use of similar to boiling water is the cuckoo sound

With the hardware of the computer constantly upgrading, the capacity of the hard disk is also growing, when your computer configuration is relatively high, and hard disk capacity is large (500G and above the hard disk), the hard disk disc thickness, weight, quantity has increased, compared to other small capacity hard disk, The computer in the hard disk read and write process will feel more than other hard disk sound, this is normal, as long as there is no use of the occurrence of Kaka or the situation of the crash, you can rest assured that use.

8. In use, there is a squeaking current sound

Some computers in the use of the process will appear squeaking current sound, this sound is generally due to the current changes caused by high-frequency inductance coil vibration resulting in a certain amount of noise, the change will not affect the stability and security of the system, please rest assured that use.

9. The same type of computer fan sound size is different

The fan speed is also related to system stability. If you install different operating systems, or the different running programs, including the use of different environments and CPU utilization, including the length of the boot time and so on can lead to different fan speed, there will be a difference in fan sound size.
