Not to be rude, but the link goes to the main community page and from there you have to search the threadid. This brings you back to this post. I also would like to have a link to the correct drivers for the ProBook 6550b with the HPQ0004 missing driver. I have downloaded the security software for mobile devices and for drive protection - still have unknown ACPI/HPQ0004. Running new install of Windows 7 Enterprise x64.

Sometimes that Device ID can also be a missing quick launch buttons/hotkey driver:
If your PC has a webcam and it isn't working you can try the driver for that too.
