After reset, I found the buttons on the left to turn up or down are not responding. What can I do?

Hi @pcsl,

As I understand the volume button doesn't work on your PC,

No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution: 

To provide you with an accurate solution, I'll need a few more details:

What is the product number of this computer? (Ensure you do not share any of your personal information such as serial, phone number, email ID, etc...).

Wen did this start to happen? Was it after an update? Has it always been this way?

Have you performed any troubleshooting steps before posting this on HP Forums?

In the meantime, you could try to uninstall and reinstall the audio drivers, as volume and mute functionality should be provided by the audio driver, using this link.

What is the product number of this computer?

Mine is 12-a001dx

After I finished the reset (Full reset), I found the volumn buttons on the left don't work. But the control on the keyboard or on touch screen work. It can produce sound. So I don't think it is the matter of the sound card.

Hi @pcsl,

Thank you for replying,

I appreciate your time and efforts,

As I understand you have tried the steps suggested and found that volume button on the left does not work, In this scenario, I would suggest you run a sfc scan on your PC.

To run System File Checker in Windows 10:

1.  Press Windows Key + X

2.  Click Command Prompt (Admin)

3.  Type in:  sfc /scannow

4.  Press Enter.

Please try this step and let me know how it goes for further assistance.

Eagerly waiting for your response!

I hope you have a good day ahead,

And Feel free to ask your queries as this forum has some of the best people in the world available and ready to help.

What is the system file scan used for? What results will there be?

Hi @ pcsl,

Thank you for getting back to us,

I understand you want to know why do you need to run sfc scannow, don't worry I'll be glad to help you with this,

System File Checker scans protected system files and checks the versions to make sure that all Windows files are where they should be and that they are not corrupt. If System File Checker finds a protected file has been damaged or overwritten, it replaces it with the correct file.

I would suggest you try to follow the steps suggested in the previous post and get back to us with the results for further assistance.

I have tried sfc scan. It did not help.

Then, I turn on HP support programme which is installed in the system. It checked for hp updates. Now, the buttons work.

Thank you.
