Hello,  I've been on the phone half-a-dozen-times with Dell and have come to no good conclusion. I purchased a Hardware & Software warranty- but Dell won't take back the computer so they can re-install the correct driver to make it work. They've sent me a few different drivers and they didn't work. I've saved everything to a 'Click-Free' hard drive and reformatted the hard drive with the USB stick I made when I first got the Dell. That still didn't work- and Dell has no comment.  So, I'm cutting my losses and am eBaying the Dell Inspiron 17R SE 7720. I've spent too much time trying to get this piece of garbage working. I still enjoying my Dell Latitude D630- even though it is a Core 2 Duo 2ghz machine and it runs Windows XP. I really can't say many good things for Dell's Tech support... If I knew how to speak Hindi (everyone is in India) I'd be able to get good service. The best thing I can tell you is GET A MAC! My MacBook Pro and iMac is way more stable and Apple's Tech support is the best! Regards!
Hi DELL--Rajath N & Kiran; I saw your very excellent support you've given to many users here on the Dell Support Forum. I've been on the phone several times with many good Dell Technicians.. but nobody can seem to figure out how to get my MIDDLE Waves MaxxAudio button to work. I have a great machine- a Inspiron 17R SE 7720 running Windows 7 with 8gb of ram, 1tb hard, and a 2gb nVidia GeForce 650M video card. Initially the MIDDLE Waves MaxxAudio button worked but stopped! The BIOS is still A01 (even though the latest BIOS is A11- I was told today by Dell NOT TO UPDATE the BIOS). I did indicate I tried to update the BIOS, but like I said the Dell Tech said I wouldn't be able to apply the update to this machine! How do I get the MIDDLE WavesMaxx Audio button to work? When I select Dell Audio in the ControlPanel- it does nothing! Please help me!
