Unknown device in device manager (code: 28)

[thepie69]

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.

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 w7 that you installed.

 

[thepie69]

I got my laptop with everything already installed on it

 

[Britton30]

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

 

[thepie69]

Its a HP Pavilion "quad edition" dv6t-6000. Intel and AMD radeon hd 6700 gpu's (switchable graphics). Came with win 7 home premium.

Where is the model number, lol. Also with my lag issue, I just noticed on my swithcable graphics when I have the intel HD one running it is running. (obviously) But when I choose the Radeon one I notice that intel and radeon are running and only radeon should be running not intel. How do I fix this. I swith them using the catalyst control center program that I put back on this hard drive btw.

There should be a sticker or tag on the bottom with the model number.

The CCC often can cause trouble. You can try this:

Try these steps to install only the graphics driver.

1.Download the preferred driver and save it to the desktop.
2.Double click the installer and you will see a screen where it will be extracted to, change that to your desktop.
3.Open Device Manager through Control Panel.
4.Expand Display adapters and right click the name for yours and choose Update Driver\Browse my Computer. Select the driver folder you just saved on the desktop. Click Next.
5. Your system should say "Windows has successfully updated your driver software".

If you get a window saying you already have the most current driver, go back to step 4 and choose Uninstall Driver software instead. Then restart from step 3.

Hopefully your BIOS has an option to disable the onboard Intel graphics chip. Being OEM, it may not though.
