On my Dell Studio XPS 16, there are digital buttons which control wireless (on & off), volume (up & down), mute, eject, etc.

Currently, these digital buttons become glitchy and get triggered even though I didn't touch it at all. Because of this, sometimes it mutes itself, randomly adjusts the sound, and turns off the wireless connection.

I don't want to go to the service center to fix the buttons since it will cost me (my warranty is over).

Can I disable these buttons through software? I am using Windows 7.

Not an answer to your actual question, but I had exactly the same issue, and it turned out to be a hardware problem. I was under warranty, and dell replaced the palmrest (the entire plastic facade including the media buttons). You might be able to buy the part second-hand? I never found a way to disable these. –  Geoff Apr 27 '12 at 13:18

Sorry - someone might still have an answer about disabling the buttons through software, though –  Geoff Apr 27 '12 at 14:49
