critical low power action after removing power cord

Binary package hint: acpid

The system performs the configured critical low power action after removing the power cord even if the battery if fully charged.

My current work around is simply to configure hibernate instead of suspend to disk as the critical low power action.

But nevertheless IMHO Lucid Lynx is a great release.
