What to do if the laptop motherboard fan does not turn

Sometimes our laptop board fan does not turn, what should we do? Then the following is to learn the small make up to you to say that the laptop motherboard fan does not turn the solution bar, hope can help you Oh!

Portable motherboard fan does not spin reason:

1, to confirm that the computer operation is normal? for example, whether there is no automatic power, restart, panic and other features of abnormal phenomena.

is the cause of the fan itself, such as shaft or motor damage. This situation generally has a gradual process, from the noise to the abnormal sound, the last stop does not turn.

Is the reason for the motherboard circuit, this situation is more common.

2, if the computer operation is normal, you can rest assured that use.

The current computer cooling fan design, is basically the use of intelligent temperature control system, according to the changes in the heat of the host intelligent adjustment fan speed. Fan does not turn, indicating that the current workload of the computer is not enough to need to start the fan for cooling, heat sink, heat pipe, heat dissipation hole, shell these can meet the need for cooling.

Important reminder: As long as the computer runs normally, there is no automatic power off, restart, crash and other features abnormal phenomenon. Can be used with ease. Once the cooling fan appears unstable, resulting in poor heat dissipation, when the temperature exceeds the factory preset temperature, the computer will take the mandatory power off, automatic restart, etc. to protect the computer. Please feel free to use.

3, if the computer operation has abnormal features, or feel uneasy, or need maintenance, maintenance, please contact the nearest service station.

The solution for the laptop fan does not turn:

For the notebook fan itself caused by the failure, the best solution is to clean the fan first, but this method to solve the problem of the basic probability is not high, eventually to replace the fan to solve. When your notebook has an automatic shutdown, crash, blue screen and other failures, you should first consider whether the heat is caused by. Because the first effect of the laptop fan does not turn is the heat dissipation problem.

How to tell if a laptop fan is not spinning

Can be on the boot of the instant through the heat sink to observe the fan has not turned, and some models are just a few fan blades shake a few, need to open the machine to see, such as Dell Notebook is so, or run a large program to allow the notebook to reach the upper limit of the temperature of the fan. Because the notebook fan is usually only the temperature reached the BIOS predetermined limit, only start to rotate, and often not fully operational, divided into several gear speed to run. This is also for the purpose of power saving and noise reduction, the general office and the Internet by the fan heatsink can be dealt with.

The motherboard circuit caused the fan to not turn

After the fan itself is excluded from this factor, another reason is the motherboard circuit failure. Fan is mainly controlled by EC, and the EC emits fan control signals according to the temperature information provided by the CPU temperature monitoring circuit. Simple sometimes only power transistor damage, complex involves many components, such as temperature control circuit. IBM notebook repair In the relevant circuit failure, such as H8 temperature monitoring circuit has problems, will be reported fan error errors.

Because the notebook is not like a desktop as the accessories are extremely versatile, different models of notebook computer fan is also a big difference, notebook disassembly also requires a bit of relevant skills and experience. Recommendation: When you encounter a notebook fan does not turn this type of failure, it is best to find their own notebook computer repair manual, or find a professional notebook repair business to solve.

The notebook fan does not turn, may want to cause the attention, cannot send to repair, most likely is because the motherboard circuit or itself damage, at this time, the best clean fan even replaces the fan. If this is the reason for the motherboard, then it is necessary to see if the motherboard circuit has failed.
