I bought a dv4-1225dx the other day and wanted to wipe it clean and start from scratch. For compatibility issues I also went from Vista Home Premium (64bit) down to Vista Home Premium (32bit).
I've been able to hunt down every driver except for an unknown device called, "hpq0004".
From what I can tell it's the HP Mobile Data Protection System.
Anyway, I've tried to run the sp33696.exe quickpac but it fails on my system every time because the "platform isn't supported". Also, this looks to be software and not a chipset driver.
Solved! View Solution.

For this error under Windows 7 on a dv3z-1000, the driver file is sp45501.exe
I am not certain of how/where one can find it for other models, but for this particular model computer, I found it in the section labeled Software - Multimedia, and it was named HP ProtectSmart Hard Drive Protection. When I ran the file, a window informed me that 3D Drive Guard would be installed.
For Windows 7, in Device Manager, the error Unknown Device disappeared and was replaced, in the System Devices section, by a device named HP Mobile Data Protection Sensor.

Same thing on my fresh install of win7 on Probook 4530s.
For mine it is NOT 3D driveguard or validity. Tried multiple times to update. I still get ACPI\HPQ0004 unknown device ID
