Public bug reported:
When I close the lid of my laptop everything seems to be fine on the
suspend procedures. BUT the laptop eats all the battery in few hours.
This is an exerpt of the syslog in which you can see that the suspend
procedures are interrupted before the complete suspend, then go on after
I open the lid to be immediately followed by the resuming

Very interesting is that there are error messages on the screen that
appear before the login screen appears, but it is too fast to read
anything and I did not find a way to capture that screen.
