There is no sound from the laptop speaker, and there is sound when you connect the headphones:

Laptop sound can be output from external headphones and speakers, but not from the laptop's built-in speakers. If you can't remember if you did something special, it's most likely due to a problem with your audio settings.

Answer: Hello, there are many reasons why laptop speakers have no sound. Because I don't know what exactly happened with your laptop. So I'll tell you all the reasons why my laptop speakers don't make sound.

The first is the sound card driver. In many cases, it is the sound card driver that causes the computer's speakers to have no sound. It is recommended that you first update the sound card driver with the driver wizard or the driver life detection.

Generally, if it is a problem with the sound card driver, it can be restored to normal as long as the update is detected.

If it's not a sound card driver issue. That's something else. It is recommended to check whether the audio device is enabled first, and right-click on my computer.

Then select Device Manager. Then take a look to see if the sound card inside is enabled. If not, enable it.

If the sound card driver in Device Manager is enabled, your laptop still won't produce sound properly.

You use the headphone plug back and forth to plug in a few times, to see if it is the reason for the headphone jack, if not, it means that the speaker of the pen and the computer connection is broken, because the connection is in the shaft that often opens the cover, so sometimes it is easy to break, dare to go down, just open it, don't dare to get the after-sales repair.
