My inbuilt webcam isnt working

Hi,

Installing XP on this C785tu is not recommended by HP as these notebooks are designed for Vista.

HP don't have the Xp drivers for this notebook. Anyhow, I will provide some work around XP drivers for this model, that may work.

List may looks long, don't worry:


Your model of Presario has an audio controller that supports the high definition audio. You
need to have Microsoft Universal Audio Architecture (UAA) Bus Driver for High Definition
Audio installed on the computer before installing the audio driver.

Here is the link for the Microsoft Universal Audio Architecture driver that need to be
installed before installing the audio driver:

ftp://ftp.hp.com/pub/softpaq/sp33501-34000/sp33867.exe

Note: Please copy the entire link starting from "ftp" to "exe" and paste it in the address

bar of the browser in your computer and press enter.

After installing UAA driver please restart your notebook and install audio dirvers
Conexant CX20549-12 High Definition Audio driver:
ftp://ftp.hp.com/pub/softpaq/sp36001-36500/sp36090.exe


Note: Please copy the entire link starting from "ftp" to "exe" and paste it in the address

bar of the browser in your computer and press enter.
Installing this driver may result in an error. But continue with the following steps to get the audio driver installed correctly.

1. Click on Start and select Run. Now type devmgmt.msc and press enter.
2. In the Sound, Audio and game controllers options Right click on "Audio device on High Definition Audio Bus" and click Update driver.
3. Select "Install from a list or specific location"
4. Click Next. Then select "Don't search, I will choose the driver to install"
5. Click Next and then select "Sound, video and game controller" from the list.
6. Click Next and then click Have Disk.
7. Click Browse C:\swsetup\sp36090 or C:\sp36090 folder and the double click the XP32 folder. Select the
.inf file, click open and Continue with the onscreen instructions.
If the above provided driver for Audio not works then go with the below link.
