>Description:
The suspend state on my laptop (HP Probook 4510s) works, the computer is suspended and the power led starts to blink.

When trying to resume, the screen does not wake up and stays at the powered off state (not black) completely off. I can hear the speaker noise (when my snd_hda(4) attach it makes a little sound). And then the system seems completely freezed because even pressing the power button does not power off. Only hard reboot can solve.
>How-To-Repeat:
acpiconf -s 3 (probably) on a HP Probook 4510s, or try gnome-power-manager.
