HP PAVILION DV7 3000 CTO Entertainment Notebook NQ339AV

I have had this notebook for a year without any problems. But starting Feb 2011 the touch panel above the keyboard have been a pain in the ass. Similar to the symptoms of the post above, its sound goes louder or softer at its own will, then the wireless light will turn amber from blue by itself and vice versa. When it is stuck on amber for a long time then it is very very frustrating because I could not access the internet.

Had updated the sound and wireless drivers but did not help a bit. The warranty is out already because manufacturer's warranty lasts only a year.
