The 'Suspend' function might, and I stress, only _might_ be affected as far as waking. This is done by the BIOS, so OS configs won't affect it. That's when you press and hold the power button for 10-15 seconds and it shuts down your PC by force. You'll still be able to use the 'hard' Power button.
You'll need to click 'Power Off' or whatever to power down.
