The volume keys on my USB keyboard stopped working out of the blue. Pressing the volume -, volume - and the mute button did not make a difference.
But I was able to fix it after some basic troubleshooting.
There are a few things that you can do to rule out a hardware/software issue.
If you have done all that and are still facing the problem, proceed to the next section.
This may sound silly, but have you tried rebooting the computer? This simple step fixes a lot of computer related problems.
My HP 100 Wired USB Keyboard is fairly new. We got it a few weeks ago, and it had been working fine. All other keys on it worked perfectly, except for the three multimedia keys. The laptop's volume keys had no problems, the speakers and headphones were all fine. After doing all the above mentioned steps, I was nearly convinced that the problem could be hardware related, and that I should get the keyboard replaced under warranty.
There was one more step I could try, Googling for the issue. In this case I had to look up the keyboard model number + the issue I was facing. It's possible that the problem is a known issue, and a fix could be readily available. That is precisely how I found the solution on HP's forums.
This is optional, but to avoid manually doing this every time, click on the "Open Services" button in the Task Manager window. Or press Win+ R and type "services.msc" and hit enter. The service has a slightly different name than the one in the Task Manager, it is called "Human Interface Device service". Right-click on it and select properties. Select the Startup type and choose "Automatic" from the drop-down menu.
That's it. This solution isn't necessarily limited to the volume keys, it could potentially help fix issues with other special keys on your keyboard.Advertisement
