Windows 7: Unknown device in device manager (code: 28)

I got a new hard drive for my HP Pavilion DV6T-6000. Installed windows 7 ultimate and a bunch of drivers from HP's drivers section for my computer and I still have this unkown device. It wasn't there on my old drive so something isn't right here.

Location: on Microsoft ACPI-Compliant System

Status:
The drivers for this device are not installed. (Code 28)
There is no driver selected for the device information set or element.



To find a driver for this device, click Update Driver.

Hardware ID:
ACPI\HPQ0004

Hopefully something I posted is usuful for one of you guys to figure out.

Yep it was the smart hard drive driver, I forgot about that one. Thanks again.

Cool. glad to help!

Hey I had another question, on my laptop I have a num lock key and usually when I hit it in the bottom right hand corner it says num lock on/off but since my new hard drive it hasn't said that.

You can try this Software & Driver Downloads HP Pavilion dv6t-6000 CTO Quad Edition Entertainment Notebook PC | HP® Support It appears it came with XP so this may not work.

I'm not sure which one to download, I've installed alot of those drivers on my PC already. Also I was just playing a game using my AMD Radeon HD 6700 GPU and it just seems to be slow and a bit laggy. Im not able to achive my 60fps anymore. I just keep having the feeling that my laptop just inst the same as it was on the old hard drive.

Use the one for the same 32 or 64 bit Windows 7 that you installed.

I got my laptop with everything already installed on it

Hmm, I saw only XP drivers. What is the full model number?
