Cause:

  2. Click Playback. Right-click Speakers and select Properties.

     

  3. Click Levels and make sure that you have enabled and unmuted the speaker.

     

• There is a fault with the audio driver.

• The ambient temperature is too high. As a result, the speaker self-protection function is enabled, causing it to be temporarily muted.

  If the ambient temperature is too high, the computer will lower the power output of the speaker to prevent the speaker from burning out. Try to keep the computer cool and well ventilated. If you are in an extremely hot environment, place a cooling pad under the computer. The speaker volume will return to normal when the computer cools down.

• If the issue still cannot be resolved, back up all of your data, and press and hold F10 during computer startup to restore it to its factory settings.
  

  System restoration will delete all data in the C drive, and files in other drives will be retained. To avoid data loss, it is recommended that you back up C drive data including desktop files, downloads, documents, and other personal files. Remember the Microsoft account and password that activated the Office components on your computer. Office components do not expire after the computer is restored to factory settings. Enter the Microsoft account and password bound when activating Office components for the first time, and reactivate Office components. Different versions of the F10 function operation interface may be slightly different, operate according to the actual interface prompts.

  

  My computer charges slowly when I'm playing games on it

  When your computer is charging, a portion of the charging current will be used to charge the battery, while the remainder is used to run the computer. CPU-intensive games consume a lot of power, which causes your computer to allocate more power to running the games and less to charging the battery. This causes your computer's battery to charge slower.
