Problem

The HUAWEI laptop heats up or the fans generate loud noise.

Cause

• When a laptop is used for large-scale games, video conferences, new device configurations, system updates, antivirus scanning, a large number of programs running in the background, it heats up due to high power consumption, and the fan speed automatically increases for heat dissipation, so the fan sound is loud.
• When a laptop is connected to the Internet through a power adapter and the system usage is low, the system automatically updates, and the antivirus software and third-party software automatically run in the background. As a result, the laptop continuously runs with high power consumption and heats up, and the fan sound is loud.
• When a laptop is connected to a power adapter for better performance in the same scenario, the power consumption of the laptop is high and the fan sound is loud.

Solution

 

• It is normal that the laptop heats up and generates fan noise in summer.
• The air outlets of a laptop are usually located at the hinges, so the temperature in the lower part of the screen and the hinge area (the area above the F1–F12 keys/the contact area of the screen) is higher than that in other areas. This is normal and does not indicate an issue with your device.
• When a new device is configured, it is normal that the device heats up or the fan sound is loud. After the configuration is complete, the temperature and fan sound will return to normal.
• HUAWEI laptops have passed strict tests to ensure that they meet the required temperature safety standards, including complying with both the Chinese national standard (GB 4943.1) and the EU standard (EN 60950-1). There are multiple temperature sensors embedded in your computer to monitor the temperature, and ensure that it stays within the safe range.
• HUAWEI laptops are preinstalled with a system before delivery. If the system is flashed without permission, the driver may be missing, the thermal performance counterbalance optimization policy may be missing, and the internal fan temperature adjustment may fail. As a result, the device heats up abnormally. It is recommended that you avoid flashing the system without permission and go to a Huawei Customer Service Center to update the system if necessary.

If you feel that your laptop is overheated or the fan sound is too loud, perform the following steps:

1. Improve your working environment by moving to a well-ventilated area.
   • Do not place the laptop on a soft surface (such as a quilt, bed, or legs). It is recommended that the laptop be placed in a well-ventilated environment with a heat dissipation bracket for better heat dissipation.
     

     The computer foot pads (black plastic bodies at the bottom of the computer) must be completely placed on a flat surface to ensure that the air inlets at the bottom of the computer are not blocked.

   • The laptop uses silicone grease for heat dissipation. It is recommended that you go to a Huawei Customer Service Center to have silicone grease re-dispensed to the heat spreader inside the device body every year, and have your device cleaned and maintained (including fan/air inlets and outlets cleaning) every half year.
   • When the battery level meets your requirements, it is recommended that you do not charge your device while using it to ensure a better heat dissipation and noise-free experience.
   • When you do not need to use the computer, it is recommended that you power it off and charge it with its lid open.
2. Clear the processes that occupy high CPU resources.

   Solutions to clear processes with high CPU usage are as follows:

   Process Type	Process (Example)	Recommended Solution
   Third-party apps	iQIYI auxiliary program Youku accelerator 360 antivirus protection Tencent Video/Tencent Meeting DingTalk meeting 360 Wallpaper HUAWEI Mobile App Engine/Simulator/Mobile phone apps …	Press Ctrl+Shift+Esc to open Task Manager. On the Processes tab, right-click the unnecessary programs and select End task. If this is the first time you open Task Manager, see Opening or hiding the Processes tab in the Task Manager Window to open the Processes tab.
   System processes	Windows Update …	Disable the corresponding services. Search for services.msc in the search box in the lower left corner of the computer screen, right-click the corresponding services, click Properties, and set Startup type to Disabled or Manual.

3. Uninstall common bundled software such as third-party antivirus software and non-authentic software.

   Microsoft comes with security protection software (Windows Security). You are advised to uninstall or exit common bundled software such as third-party antivirus software and non-authentic software.This type of software causes high usage in the background, features poor stability, and may conflict with the system. It is recommended that you clear the software in a timely manner.

   

   When the Microsoft security protection software (Antimalware Service Executable/Microsoft defender antivirus service) scans the system in the background, although the CPU usage is low, the system power consumption is high, the laptop heats up, and the fan sound is loud. This is normal and does not indicate an issue with your device.After the scanning is complete, the temperature and fan sound of the laptop become normal.

4. Optimize the computer settings.
   1. In daily basic work, check whether Performance mode is enabled by referring to Enabling or disabling Performance mode on my laptop. If so, disable Performance mode.(Skip this step if your device model does not support Performance mode.)
   2. Set the power plan to Balanced.The operations vary depending on the system version. The following uses Windows 11 as an example:
      1. Press Win+R to open the Run dialog box, enter control, and click OK to access Control Panel. Then go to Hardware and Sound > Power Options > Selected plan > Change plan settings.

         

      2. Go to Change advanced power settings > Balanced [Active] and click OK.

         

         

   3. Optimize the power mode.
      • For Windows 11, you are advised to set Power mode to Best power efficiency. To do so, click the Start icon, go to Settings > System > Power & battery > Power mode, and select Best power efficiency.

        Click to go to Power & battery.

        

      • For Windows 10, it is recommended that you set the battery mode to Battery saver. To do so, click the battery icon and set the battery mode to Battery saver.

        

   4. Reduce screen brightness.

      It is recommended that you lower the screen brightness based on your usage. To do so, click the battery icon to adjust the screen brightness to a proper level.

      

5. Disable programs that you do not need upon startup.

   Press Ctrl+Shift+Esc on the keyboard to open Task Manager. Click Startup apps (Startup in Windows 10), right-click a third-party app that does not need to automatically start upon system startup, and select Disable.

   

   The following figure shows the user interface in Windows 11.

   

If the issue persists

If the issue persists, back up your data, record your Office account that has been activated, and use F10 to restore your device to its factory settings.If the issue remains unresolved, take your device and proof of purchase to an authorized Huawei Customer Service Center for assistance. (Tip: Feel free to call the Huawei consumer service hotline for assistance before going to a Huawei Customer Service Center.) We will do our best to address your needs.
