I use Lenovo Thinkpad T500. It has a power button that is not registered when pressed. When I run xev and press the button, nothing happens. The button works when held for about ten seconds - it then turns the computer of (with no shutdown procedure).
I think it might be related to this bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/281732
I the ubuntu kernal crew will not fix this, could you please forward it upstream?
