I have a HP Pavilion DV9700 laptop running Vista which was fine until yesterday when I decided to install some windows updates. 3 out of the 4 installed successfully. Since then the sound doesn't work & the little touchpad mute button no longer turns orange when touched.
I tried system restore several times but on restart the message "System restore was unsuccessful & your files have not been changed" (or similar) I tried to roll back the Conexant driver to see if that would work, it didn't. I did a search & downloaded & installed the driver again...nothing.
I did the diagnostic check & it says everything is working. I've done a little browsing around & it seems there are a few similar problems with this. Any ideas please?
I'm a novice too so that doesn't help much.
