ACPI/HPQ0004 PCI Unknown Device Driver [solved]
Q. Hello, I have a HP laptop showing ACPI/HPQ0004 unknown device and I need to find the right drivers. I saw you helped Dell users with a similar problem… Can you help me with this one too? Here is the deal:
Clean Windows 7 install on my HP Pavilion DV6. Every other HP driver is working perfectly and Device manager looks great EXCEPT!!! I have an unknown device with listing ACPI/HPQ0004. Please help as I really want to get the right drivers for Windows 7 so my laptop will be in good shape. Thank you in advance for your help! -Paul R.
A. Certainly, I am glad to help. Here is a driver for Unknown Device ACPI/HPQ0004
HP driver dl link (ftp)
[download id=”10463″ format=”1″] (http)
Those links are for an HP Service Pack/Driver that will install 3D Driveguard and should solve the Unknown Device in Windows 7 Device Manager. Let me know if it works for you!
Q. UPDATE from Paul R.
THANK YOU, that finally solved my problem!!!!

Wow this is a good fix I can’t believe I finally got this issue fixed. It’s been an issue for years and I’ve previously tried via HP sources etc. and given up in the past. Now I’ve upgraded to Windows 10 on my laptop and still had the same unknown device issue so I decided to search found this site gave this a whirl and waaalaa! Too bad HP can’t resolve this via there trouble shooting methods.
That is awesome news Matt! Enjoy your nice HP laptop and Windows 10 🙂

Hey, thank you. That was driving me nuts. I did a clean install about a week ago and everything is was perfect. I even downloaded a different version of HP’s 3D drive manager and it came up saying there was no supported hardware in my system (go figure). Anyways the link to the service pack you had did the trick. The laptop is an HP Elitebook 8460p
Hi Thomas,
Thank you for your nice comment. I am very glad to hear that the linked service pack fixed the issue on your Elitebook 8460p 🙂
