Hi Reality,
has this problem appeared suddenly or has it done it since purchase? Also as it doesn't appear to hinder you in any way I just wonder if it's much to be worried about. I guess the only way to find would be to ask another owner of the same lappie and see if they have the same 'problem'.
If your really concerned about this issue it might be worth contacting Gateway support which can be found here:
