This sounds like a permissions issue. What distro are you running?
What's the relevant output from:

killall gnome-power-manager
gnome-power-manager --verbose --no-daemon

You might want to look at the suspend failed message. 

Also, as a user (rather than root) can you try:

dbus-send --system --print-reply --dest=org.freedesktop.Hal \
/org/freedesktop/Hal/devices/computer \
org.freedesktop.Hal.Device.SystemPowerManagement.Suspend \
int32:0

As this might help debug the problem. 

Thanks,

Richard.
