On my Lenovo 3000 N200 laptop, the suspend and hibernate functions work when I invoke them from the KDE4 logout dialog. However, the Sleep and Hibernate keys (Fn-F4 and Fn-F12) do nothing when pressed. They don't seem to generate ACPI events - the system log shows nothing when they are pressed. How can I set up these keys to work? I'm running lenny. -- David Jarvie
