[...] Incidentally I use NFS to a file server on my laptop, over wifi, and I close the lid for the night. It's NFS mounted soft. If it was mounted hard I wouldn't expect the lid close event to result in a successful suspend if wifi went down - but with soft I would be pretty sad in the morning if batteries drained if I closed the lid after there's a power outage which took down both wifi and the laptop power supply. Closing the lid while on battery is a pretty strong command from the user. Arguably this is a special case on several levels as on desktop distros it's not at all easy mount NFS shares (all point & click automation goes to Samba shares), just wanted to mention it. Thanks, Ingo
