Howto put linux in sleep mode at 1 am and wake up at 6 am automatically

Geert86 · 01-04-2010, 03:42 PM

Well, my question is pretty simple, the answer is not I think.

Is it possible to let a Linux PC put itself into sleep mode at 1 am, and wake up, by itself at 6 am?

Best regards,

Geert

You can set the machine to sleep at a particular time, but it needs an external event to wake it.

use the command "at" to schedule time to sleep

at 0100
>pm-suspend
<ctrl-D>

as for waking up:
tie a weight on a string above the power button
position strong magnifying glass to focus the morning sun's energy onto the string

lol

usually when I see a request like this it is because of some Windows program which claims to perform the task.

I've got a Dell Optiplex 740. I suspend it to disk as & when I'm finished with it for the day & a bios setting powers it up at 0600.

Thanks for the help. My Bios does support Wake On Timer, so am gonna try that combined with sleep in cron file

What is the sleep command. pm-suspend does not work (it gives no error, but also no action, did it as root user)

Best regards,

[PS. it is to save power during the night automatically, because the server is only used for file sharing and showing pictures in our hal)

I now put PM_DEBUG = true pm-suspend, and it ouputs now:

Code:

++ '[' -f /etc/pm/config.d/pm.conf ']'
++ '[' '' ']'
++ '[' '' ']'
++ '[' '' ']'
++ '[' '' ']'
++ set -a
++ . /etc/pm/config.d/pm.conf
+++ SLEEP_MODULE=kernel
+++ PM_DEBUG=true
+++ pm-suspend
++ set -a

++ '[' -f /usr/lib/pm-utils/defaults ']'
++ . /usr/lib/pm-utils/defaults
++ set +a
++ for cfg in '"${PM_UTILS_ETCDIR}"/config.d/*[!~]'

This seems to repeat forever, so I closed the process.

I have no idea what can be wrong...

rich_c · 01-05-2010, 02:35 PM

The thought of automating the suspend never crossed my mind. As I mentioned, I just suspend it manually when the family are finished with it for the night.

man rtcwake
This program is used to enter a system sleep state until specified
wakeup time.

This uses cross-platform Linux interfaces to enter a system sleep
state, and leave it no later than a specified time. It uses any RTC
framework driver that supports standard driver model wakeup flags.

This is normally used like the old apmsleep utility, to wake from a
suspend state like ACPI S1 (standby) or S3 (suspend-to-RAM). Most
platforms can implement those without analogues of BIOS, APM, or ACPI.

On some systems, this can also be used like nvram-wakeup, waking from
states like ACPI S4 (suspend to disk). Not all systems have persistent
media that are appropriate for such suspend modes.

In Ubuntu 9.10

pm-suspend is part of "pm-utils", and you may need to configure it first.

Look in /etc/pm/
man page gives some info about these files.

pm-suspend
# sleep to ram
pm-hibernate
# suspends to hard-disk

suspend wake up quicker
hibernate will save more power

Geert86 · 01-06-2010, 07:09 AM

I have 3 folders in /etc/pmp/:

config.d/
power.d/
sleep.d/

They are all empty. So what to do know?

Best regards, Geert

what is wrong with rtcwake?
what is your distro?

do you have acpi enabled? (you can sleep etc right?)

Geert86 · 01-07-2010, 04:17 AM

Through BIOS I have ACPI enabled. I can choose for the suspend mode between:
- suspend to disk
- power on suspend (or something like that)
So it seems my bios does not suspend to ram

I have never succeeded to put my computer into sleep mode, or hibernate mode

My distro: Debian Lenny

When using rtcwake:
razer:/home/hurman# rtcwake -s 3700
rtcwake: wakeup from "suspend" using /dev/rtc0 at Thu Jan 7 11:15:58 2010

And than it does nothing... strangely enough the rtc wake time seems to be in GMT time, while, I am in +1 Amsterdam time. But it does nothing when I do this command.

The same for
pm-is-supported --suspend
It does absolutely nothing

Hibernate is available from the menu, but everytime I do it, it fails... (so it hibernates, but when I want to turn it on again, the first time I press the power button it does load, but not fully. The second time i do a hard reset and it works.

So any ideas ?

Interesting

also see
http://ubuntuforums.org/showthread.php?t=938533

acpi handles sleep etc.

dmesg | grep -i acpi

debian lenny? - and machine?

Because software suspend is still experimental, it is not enabled by default on most machines. Depending on your system, a few more steps are needed to get suspend partially or fully working.

Hi,
