Lenovo G485 notebook volume small speaker, why can t I double click and lower it?

There's a little speaker in the bottom right corner of the computer, and you can double-click on it to turn up the volume, and you can rip off all the external things, and then restart it, and it should be ready to use.

Dear Lenovo users, hello:

Please uninstall and reinstall the sound card driver to see if this solves your problem.

Cause: Your computer has been infected with a Waveform Silence virus

Waveform mute virus process file:

2) Delete in safe mode.

c:\windows\system32\

c:\windows\

Or delete with the Force Delete tool.

3) The latest variant may not have the above files, you need to manually remove the boot auto-start item, and use anti-virus software or stubborn Trojan horse to kill and kill after restarting.

Start Run Enter msconfig to start.

Remove the checkmark before C: Windows and C: Windows System32 and reboot.

Note: Method 2 above does not target mutant viruses.

4) The easiest way is to deal with it directly with antivirus software, and most mainstream antivirus software can deal with it in the current version.

Hello,This may have something to do with the audio output power of the notebook,The audio output power of the notebook is generally smaller than that of the desktop,And some speakers need more power to push,Usually some speakers need to be connected to an independent power supply,Therefore,See if your speaker belongs to the external independent power supply。 If not, then there are two ways.

First, change to a less powerful speaker.

Second, the notebook is connected to the power amplifier, and then the power amplifier is connected to the speaker, and the power amplifier can provide more power.

Another point is to look in the driver panel,Whether the external speaker is correctly identified。

The color of the jack is not the same when plugged in and when the device is unplugged.

Basically, that's the problem.

It should be emphasized here that whether the speaker has an independent power supply and active and passive sound are two different things. Both active and passive speakers are available with and without power supply.

To put it simply, passive speakers must be connected to the power amplifier in order to use normally, while active speakers only need to be connected to the signal cable (if the speaker has an independent power supply, please also connect).

Active speaker: Built-in power amplification circuit, which can work when the power supply and signal input are turned on.

Passive speaker: There is no internal power amplification circuit, and an external power amplifier is required to work.

The market positioning and consumer groups of these two types of speakers are different:

Active speakers are now mostly used in many fields of computers, and some occasions with special needs (such as electronic organ speakers) This kind of speaker generally has a small output power, the volume cannot be turned on very much, and the circuit of the power amplifier is not too particular, it is a simple audio system.

Passive speakers belong to formal audio, with high power and good sound quality, but the product is large and bulky.

Dear Lenovo users, hello:

BIOS Restore Default Settings Method: When the motherboard logo appears at boot, tap F1 continuously to enter the BIOS, F9 restore the BIOS factory settings, and F10 is saved and exited.

If your problem is not solved, you can complain, put forward your valuable opinions, and then transfer to manual service.

You didn't prescribe the right medicine, because you didn't see your machine, and you can only make a rough judgment.

There are many reasons for silence, one is the problem of the audio circuit, the second is the problem of the speaker, the third is the problem of the connecting wire, and the fourth is the lack of signal input.
