Wow, I'm really grateful you're taking the time to help me out. Thank you!
OK, you're right on about the chip sets. A year or two back, I went to ATI to check for updates. It took some prodding, but finally was informed that DELL was the only source for updating ATI products in Dell Laptops. I still have the same install that came with my laptop, EXCEPT this laptop came installed w/ VISTA Pro/32-bit/2 GB RAM/140 GB HDD.
I've since upgraded to Win 7 Ultimate/64-bit/4 GB RAM/120 GB SSD. I Can't seem to break through the barrier on Dell's website because they won't let me put my specs in my present laptop even when I allow them to scan my laptop, it (they/Dell) shows my current specs, but still refers me to the drivers page for the original VISTA configuration. Their is probably a way in, but I haven't figured it out yet.
My audio/microphone is still not working, headset headphones are working, but the device mgr. won't allow me to override the default MS HD Audio drivers with Realtecs HD AC'97 drivers. I had the same problem with my desktop, but was able to install Realtecs drivers there and all of my audio is now working.
Sorry I'm dragging this out, but going to Device Mgr to get the device instance ID for both Base System Device and Audio Device. I couldn't find on either that exact wording. The closest I could come was Device Instance Path & a few more descriptions with the Device word, but nothing close to Device Instance ID.
This is alot to deal with. Wouldn't blame you for blowing it all off. I have tried many ways, many days on this. Want to give up myself, but not there yet.
Again, thank you for any & all time you've spent. I'll keep trying & if I come up w/ anything, I'll let you know.
