More information about the problem:
If I remove the front bezel of that cover the screen edges, this problem 
appear to go away. While the front bezel is off, I look for any switches (or 
sensors) where the front bezel goes in, especially at the bottom near the 
hinge area and could not find any. Now I am really puzzeled, what could 
cause such problem with front bezel installed?
