eeepc + rtcwake = alarm clock

pmate · 02-17-2009, 06:05 AM

Hi all,
i wish to turn my eeepc 701 (Gnu/Linux Debian Lenny) into an alarm clock.
So i thought that this worked:

Code:

# rtcwake -s 20 && pm-suspend

but nothing happened...

So i tried whith wakealarm too but got the same result:
eeepc goes on suspend-mode (obviously) but doesn't wake up. It needs that (manually) the power button is pressed to wake up from suspension.

Anyone got some experience on it?

Thanks

I'm running Debian 5.0, and I was able to put my laptop (dell xps m1330) to sleep for thirty seconds with

Code:

# rtcwake -m mem -s 30

The rtcwake command issues the sleep instruction itself. There is no need to run pm-suspend.

That's a pretty cool command. Thanks for showing it to me.

thanks for your answer,
you're totally right: there's non need to run pm-suspend.
But the problem remains: it goes in suspension and resume not after x seconds but only if i press power button. This happens only in X, in console instead, it doesn't wake up at all. I have to power off...

p.s. happy to have been useful... ;-)

That's a stinker. What kernel are you running? Is it hand rolled or did you apt-get it?

pmate · 02-19-2009, 02:30 AM

no it isn't hand rolled, it is the default kernel of debian for eeepc.
Can it be that the problem is in some of the eeepc-acpi-scripts?
Or it can depend on bios?

Well, to answer your questions, yes and yes. It sounds like your linux isn't listening to acpi events. That could be a scripts or a bios issue. I don't have any experience with an eeepc so I don't think I can offer anything more. Good luck!

I just tried this on an HP DV5020us laptop and it looks like it is a bios limitation. Same here, no wake up.
Tried it on a couple desktops that have a wake time settable in the bios and it works great from a terminal. Looks like it has to be settable in the bios (but you don't need to set it like that) to be function-able.

ok got it working try using the -u option for utc time and not local time , works on every thing i've tried around here so far!

rtcwake -d rtc0 -m mem -s 60 -u -v

no way, even with geesh's suggestions.
At this point i think it's a matter of acpi-scripts.
I will check in these days.
Thanks a lot
