Hi Eugene, Thank you for your nice comment. Hi Hamed, Thank you for your comment. Is anyone working on this problem? That was driving me nuts. I am very happy to hear that the driver worked for your HP DV5! The only glitch is the f9 key, which controls the volume muting feature. You can follow the question or vote as helpful, but you cannot reply to this thread.

Thanks for the solution, it also solved the same problem I was having with the missing driver after installing Win 10 on my Pavilion Dv7. I have the same problem for windows 10 I have an HP Pavilion gdx laptop Please let me know how to update driver.


Sorry this didn’t help. You are very welcome! The laptop is an HP Elitebook p. In reply to Jonathan Benefiel’s post on August 21, There’s a place where it asks you which operating system you are using. You can help protect yourself from scammers by verifying that the contact is a Microsoft Agent or Microsoft Employee and that the phone number is an official Microsoft global customer service number.

Or is this just something I have to live with until I get a new laptop? Enjoy your nice laptop and your fresh Windows 10 upgrade!

Hi Aleksandr, Thank you for your comment, I am very glad it worked for you! Hi I see the topic is pretty old but it was actual and useful for me as well. Intel for example has the Intel Driver Update Utility that can scan your computer and install generic drivers for the Intel products it finds.

Since you already checked with Microsoft, check with the manufacturer of the chipsets on your computer. It might be wise to visit the manufacturer site after Intel in my example – your chipset might not be Intel installs the generic driver to see if the manufacturer has a driver more specific to your computer. Everything is, for the most part, working smoothly.

Let me know if it works for you! Jonathan Benefiel Created on August 17,
