Hi Scott, I have the same issue with my power button on my Gateway 200X (which I think is roughly the same machine as the Dell X200). It appears to be an issue with fixed-feature power buttons. I opened bug 1920 to address the problem. You can check it out here: http://bugzilla.kernel.org/show_bug.cgi?id=1920 Thanks, Greg On Thu, 2004-02-05 at 21:55, Scott T.
