Don't kill it yet, see what happens. I took great pleasure in smashing my old Xbox 360 on my front walk, but only after I was sure it was dead and had a replacement.
Edit: My wife's laptop charging cable died on her last laptop and Acer wanted like $110 for a replacement. I found a Universal one on E-bay for $7.50 and that fixed it. Hope it's that simple a fix for you NDX.
