The notebook I have can only resume from standby by pressing the power butt= on.=20 Could it be, that when the power button is pressed, the system starts to wa= ke=20 up, but the "power button event" is not intercepted by ACPI and passes=20 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 gu= ys=20 to tell me just how wrong I am ;). Here's a rought flowchart of what's happening on my notebook (afer 6. is th= e=20 problem): 1. echo 3 > proc/acpi/sleep 2. PM: Preparing system for suspend 3. Stopping tasks: =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D| 4. --> Notebook enters standby. HD quiet, LCD off, fans off, On/Off LED pul= ses=20 slowly 5. Press power button to wake notebok 6. --> Notebook tries to leave standby. HD spins up, LCD light on but no te= xt,=20 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 pres= s=20 the button?
