After reimaging and using HP Image Assistant, I am left with one unknown device. The hardware ID is ACPI\VEN_HPQ&DEV_6007 This device appears to be related to either the HP 3D Driveguard or Accelerometer driver. I have looked through HP.com drivers and HP Softpaq manager and cannot find a driver for this device? HPSPM has the 3d driveguard software for the 640 G3 & 640 G5 models but not the G4's?
This package provides the HP 3D DriveGuard Software for supported notebook models that are running a supported operating system. The HP 3D DriveGuard Software protects the hard drive by parking the heads if the notebook is accidentally dropped, or is abruptly impacted by another object.
