Stupid question of the evening:

It's 5am here and I've just spent about the whole night playing witch ACPI, 
DSDTs etc...

The notebook I have can only resume from standby by pressing the power button. 
Could it be, that when the power button is pressed, the system starts to wake 
up, but the "power button event" is not intercepted by ACPI and passes 
through to "the hardware", causing the notebook to shut down for good?

I know thats in very rough laymans terms, but I hope it's enough for you guys 
to tell me just how wrong I am ;).

Here's a rought flowchart of what's happening on my notebook (afer 6. is the 
problem):

1. echo 3 > proc/acpi/sleep
2. PM: Preparing system for suspend
3. Stopping tasks: ==================|

4. --> Notebook enters standby. HD quiet, LCD off, fans off, On/Off LED pulses 
slowly

5. Press power button to wake notebok

6. --> Notebook tries to leave standby. HD spins up, LCD light on but no text, 
fans start...
7. --> Not even 1/2 second later, all off. Notebook is off. On/Off LED off

8. Press power button again.
9. --> Normal boot...

Could it be that there's some magic power-off event queued up when you press 
the button?

Thanks,
    André
