dv2810us Coprocessor?

My friends laptop crashed, so he asked me to fix it. Now after a clean install of the most basic vista version, there are five 'devices' that windows does not know what they are.

Under Device Manager,
Other Devices
Coprocessor
Ethernet Controller
SM Bus Controller
Unkown device
Unknown device


Also, when i try to instal the audio drivers off of Hp's website, it fails to install and i think this has something to do with these missing devices. Any help would be much appreciated

 

Did you download all the drivers in the HP website?

 

I pretty much did, audio, bluetooth, camera, essential updates, media card, quick launch and the software for it, the quick play web update, the touch pad, video and wireless driver. I did not find an ethernet driver on their website. May have found the coprocessor driver though. I know i did not download the fax driver, maybe i should, since that is most likely one of the missing devices?

 

Hi, I had the coprocessor issue. It was due to not using the specific video driver hp had on their website. If I used Windows Update to install the video driver, I got the coprocessor error. If I installed the driver from HP's website, I didn't get the error. Hope that helps a little.

 

Did you install the video drivers? Your model uses a unified driver architecture if im correct.

If that doesnt work, download the HP update program and let it find it for you.

 

i already installed the video driver from hp's site.

 

Looks like fingerprint reader

 

You need the Nvidia mobo chipset drivers (nForce). Not sure why it isnt available there...

Can you download CPU-z and post your motherboard info?

We have the drivers for XP located here but i cant find the one for Vista

 

i tried to install the nforce chipset, no luck, although, the fax was one of the unkown devices, so i will try the finger reader. and i will also download cpuz and post specs in a few minutes

 

This is all the information that cpu-z gives me for the motherboard.

Manufacturer: Wistron
Model: 30d6 81.51
Chipset: Nvidia nForce 560 rev. A2
Southbridge Nvidia nForce 560

Then some BIOS Info
Version F.21

 

Try this: http://www.nvidia.com/object/nforce_nf520_winVista_15.01.html

or this http://majorgeeks.com/NVIDIA_nForce_Unified_Driver_Windows_Vista_d5973.html (more updated)

* Ethernet Driver (v65.74) WHQL
* SMBus Driver (v4.60) WHQL
* Installer (v5.52)
* IDE SataRAID Driver (v9.92) WHQL
* IDE SataIDE Driver (v9.92) WHQL
* RAIDTOOL Application (v9.83)
* SMU (v1.31) WHQL

 

thanks will do, i will post back, and the fingerprint reader was not the missing device.

 

ok, i installed that, ethernet still does not work, sound through headphones still does not work, and there is still an unkown device. so getting close.

EDIT: ETHERnet works.

EDIT #2: Unknown device still there, and sound driver still does not install.

 

I usually find that installing the nForce drivers fix the coprocessor driver problem. I use one of the performance packs here (this is the Vista page): http://www.nforcershq.com/forum/actual-vista-32-64bit-driver-packs-for-nf4-7-chipsets-vt70915.html
