Lenovo SL400 heat dissipation is too poor, as soon as it is turned on, it is 56 degrees, and it is 8

Keep the virus database updated and disinfect regularly 4. Check whether the heat dissipation vent is clean 5. Whether the ambient temperature is too high 6. It is recommended to buy a *** heat dissipation bracket to help the laptop dissipate heat 7. Turn off some useless ones.

Dear Lenovo users, if your computer has the problem of excessive heating under normal operation, you can follow the following methods to see if you can solve the problem you encounter:

1. Clean up the dust inside the laptop, raise the bottom of the laptop or increase the heat dissipation base to maintain a good ventilation environment;

2. Upgrade the anti-virus software of the machine to carry out overall anti-virus and clean up the system garbage;

3. Turn off the startup items that are not commonly used, the method is as follows: press the win+r key combination to call the running window, enter msconfig, click OK, select "startup" to select the card, cancel the loader you don't need to boot, and then OK, you can turn off the boot startup of this program.

4. If the heat dissipation problem of the machine has not been effectively improved after the above operations, it is recommended that you can first try to save important files and reinstall the operating system, if the operating system is still not solved after reinstalling the operating system, it is recommended that you contact the local Lenovo service station and ask the engineer to help you deal with it.

Think service station information inquiry.

Normally, buy a fan cooling base.

1.Usually, the temperature of the Internet CPU and graphics card is generally about 50-55°, which is normal.

2.Check to see if your fan is loose or out of place, as it will vibrate violently if it is not properly secured. Also, check if the sound and vibration are coming from the hard drive? The laptop hard drive is very loud and has a clicking sound after the bad sector.

3.Don't apply too thick silicone grease, which will make the thermal conductivity worse, just moisturize it with a thin layer like lipstick.

4.Since it is a problem with the fan, then the fan is loose, maybe the screws are loose, and it is not possible to use paper pads, you can use 502 super glue to apply to the screws, and then screw it on when it is almost dry, so it is tighter. In addition, I wonder if the fan shaft is loose?

If the hinge is too loose, it will make a sound, and a drop of oil on the hinge can reduce the sound when rubbing. If it were me, I would use a mallet to smash the threads of the screws so that they wouldn't slip when screwed.

It is normal for the heat vent temperature to be high, otherwise the internal temperature will be too high.

Normally, mine too, it's better to use a radiator.

One. If your fan has no noise, if the speed is enough, it proves that your fan is not broken.

Two. If your original graphics card is not hot, only after cleaning it up. Unless the graphics card chip is broken, there is only one case:

After your machine was cleaned by the maintenance technician, the silicone was not replaced at the place where the graphics card chip was connected to the heatsink.

Note: The fan is fixed to the heatsink and is exposed to the CPU and graphics card chip through the heatsink to dissipate heat. Generally, the dust cleaning is to remove the fan, that is, to remove the heat sink first, and then remove the fan on the heat sink to clean the dust.

The heatsink is connected by silicone where it connects the CPU and graphics card. After removing the heat sink, there will be residual silica gel in the heat sink, and some teachers are almost at the same level, or they don't care. He probably won't give you a new silicone.

Without silicone, your graphics card won't be in contact with the heatsink, so it won't be able to heat at all. Your CPU temperature is not high, which means: First, there is more silica gel left in the CPU. Second, the maintenance staff only replaced the silicone of the CPU and did not change the graphics card.

It is recommended that you find the master who cleaned the dust and ask him to add some silicone to you, otherwise the high temperature will burn the graphics card for a long time.

If the maintenance man says that the level is high and the heat sink has not been removed, then ask him to change some new silicone for you and add money appropriately.

Silicone costs almost nothing, but it is a necessity for heat dissipation. There is no chance that the hardware of the notebook will break down suddenly without external causes.

Is it professional to help you clean it up? If it doesn't work, just change the fan.
