how to back from suspend without shutdown

how to back from suspend without shutdown

[Sergio Monteiro Basto]

Hi everybody,
I have a new laptop one HP Compaq NX6110 , that works quite well with
suspend and hibernation.

But after suspend , how I bring back computer ?, the only key that I
know is power button, but after press power button and laptop wake-up,
Begins the shutdown process because is triggered the power button
shutdown .
any ideas ?

Other question klaptop let me choose performance profile:
 userspace or performance, which one is better ? and why ?

Klaptop allows also to define CPU throttling which is in 00% but I can
choose 0,12 25, 37, 50, 62, 75 and 87. What is the propose of this
settings ? 

thanks in advance ,

Try building acpi button support as a module and unloading it during the 
cycle.

Hi,
unload acpid (service acipd stop)  before suspend is more easy and
works.

thanks,

Maybe you need to write a patch:

acpi_button_notify:
	if(acpi_during_suspend_resume)
		don't generate power button event to confuse user space
daemon,

for acpi_during_suspend_ruesme definition please search title 
"Power-button event after resume from S3" in acpi ML archive.

Thanks,
Luming

I agree 100% , just  more simply  and more specific 
acpi_button_notify:
	if (acpi_during_suspend_resume && power_button_event)
		don't generate event to confuse user space daemon

so the patch is this
http://marc.theaimsgroup.com/?l=linux-acpi&m=114472292910442&w=2

I don't agree with not sending other events than power_button_event. 

On my point of view, the perfect way, is have user space daemon
receiving all events after suspend less the power_button_event, because
this one was used to make machine wake up, simply like that.

Hmm,  it is an easy and ugly workaround. I bet this kind of question
would be
raised again and again on this mailing list, if no code fix exists.

I ran into that problem, too. Since the acpid stop/resume workaround
is so obvious I didn't make a lot of noise about it. But it would be good
if it worked automatically.
