I get this message when I execute powerdown

[powerdown] cannot write powersave to /sys/module/pcie_aspm/parameters/policy
[powerdown] cannot write 1 to /sys/module/i915/parameters/i915_enable_rc6

Same for me. I also have Core i3 cpu -- ThinkPad E430.

hazote: I'm also experiencing this.

Hi, this new version freezes my Gnome when not connected to AC or when I run 'sudo powerdown'. I can move cursor, but everything else is freezed.
I tried to find out which part of the script caused this so I commented all the lines out thinking I will uncommented them one by one and test it. But it freezed even with all lines commented out. When I unistall powerdown and install pm-utils instead, it work as it is supposed to.

I've installed it again and now it does not freeze. So consider it fixed, I guess
But I'm getting this, not sure how to deal with it. First line means "Write error: Operation not permitted" and sda4 is NTFS partition.

And: Is it normal that most of the watts are consumed by backlight? It sounds reasonable, but really that much?

Using the AUR or ABS, you should probably have the 'base-devel' group installed to ensure that you always have the required packages for building stuffs.

Is there any easy way to poll the current battery capacity (percentage) and run automatically the suspend-to-disk script if it is too low?

sekret · 2013-10-15 16:45:11

I have something like this in my dwm status script. Here's how it can be done:

INTERVAL=10 #seconds
BATTERY_THRESHOLD=10 #percent
BATTERY_PATH="/sys/class/power_supply/BAT0"
BATTERY_STATUS="$BATTERY_PATH/status"
BATTERY_CAPACITY="$BATTERY_PATH/capacity"
while true;do
  if [ -d "$BATTERY_PATH" ];then #check if the battery is actually in the laptop
    if [ "$(cat "$BATTERY_STATUS")" = "Discharging" ];then #we don't want the system to suspend in case the battery loads and is still <10%
      if [ "$(cat "$BATTERY_CAPACITY")" -le "$BATTERY_THRESHOLD" ];then sync;sudo systemctl suspend;fi #you'll need to allow sudo tu run systemctl without a password, or if you run the script as root, just erase sudo from the commandline
    fi
  fi
  sleep $INTERVAL
done

I'm sure there are better ways and better codes, I'm not realls a talented hacker But it works.

Some batteries send a signal every time the battery load goes down 1%. In that case you can use a udev rule. I saw one here a few months back, but can't remember where. I deleted it, because it didn't work with my laptop.

Thanks a lot, sekret!

I have the same issue, my laptop battery isn't generating uevents while discharging, so I have to poll on my own for its current capacity.

taylorchu · 2013-10-18 03:42:45

powerdown is going to have a big update soon.

feature list:
1. remove its own suspend/hibernate with systemd suspend hibernate. it is a clean up but it will still "provide" pm-utils.
2. implement systemd pre/post suspend service
3. still provide powerdown/powerup when power supply is charging
4. auto-suspend when battery is low
5. providing sugguestion on your system config error

future of powerdown
it will try to behave like windows's powersave, and work optimally without config. stay tune.

I have it set by xfce4-power-manager and I use hybrid so, the defaults is used to respect the main power manager??

PD: powerdown try to call community/x86_energy_perf_policy in my system so that is a dep now right??

Hello!

Can the powerdown/up script command screen power saving? I would like to use screen power saving only when on battery and otherwise have my monitor always on. What I tried was to set these to powerup

xset s off
xset -dpms

and powerdown

xset s on
xset +dpms

but they are not working. They do work if set from terminal.

Edit: ok, fixed this with adding the following lines to both powerdown/up

export DISPLAY=:0.0
export XAUTHORITY=/home/<user>/.Xauthority

I ran the script as indicated in the first post and I get this message:

powerdown wrote:

[powerdown] cannot write powersave to /sys/module/pcie_aspm/parameters/policy
[powerdown] cannot run mount -o remount,noatime /dev/sda4

If required, /home is mounted in /dev/sda4, while / in /dev/sda3

Please, I need this script to work as I got just ~1,30 h battery life. I have to use my laptop to study and it gotta be able to work for some hours... I don't want to go back to Windows...

PS: This is my first post and I'm a noob Archlinux user, so please take this into account.

Thank you in advance and sorry about my basic English.

pcie_aspm isn't supported on every hardware. You could enforce it with a kernel parameter, but I don't recommend doing that! My laptop also doesn't support it and after forcibly enabling this, it consumed more power instead of less power. So it's best if you ignored it.
Why the remount doesn't work I don't know. Seems a bit odd imo.

But still, if you now only get ~1,3 h battery life, I guess it won't be possible to suddenly make it go up to "some hours" like you requested. How long does your laptop run when you use windows?

frank604 · 2014-01-23 00:08:34

Hi Taylor, I used this awhile back on my asus laptop and now I'm running a macbook air 6,2 13". Just wanted to say thanks and the udev rule is activating powerdown perfectly. I have a not-so-related-question in regards to keybinding a toggle for xset s off/on and dpms off/on. Anyone here have a script that I can bind to a key (F4) to toggle between them? That way, while on battery, if I want to watch a video, the screen doesn't blank out etc etc? And I can toggle it back to go to power saving?

sekret · 2014-01-23 07:48:09

Don't video players handle this? My screen turns off after 10 minutes of inactivity, but when I play a video in mpv, it stays on.

jakob · 2014-01-23 07:57:19

Video players yes, but flash streams no.

I just installed it as per the rules on the front page. grabbed the package, and added those parameters.

however, after doing a "ps aux | grep powerdown" i didn't see anything. i also noticed that there wasn't any need for a systemd enabling of a daemon. i am skeptical that it is working. how can i check that?

cris9288 · 2014-03-04 02:38:37

powerup and powerdown are scripts that live in /usr/bin and are triggered by a udev rule. Try running the scripts (/usr/bin/powerdown and /usr/bin/powerup) from the commandline, running /usr/bin/powernow inbetween to see the difference. Also test this by unplugging the power and running powernow.

Many thanks for your script. I was under a great dilemma, I use TLP on Ubuntu and it works quite good. However on my Arch laptop that has Optimus, TLP worked fine as long as I used Bumblebee, recently kernel 3.12 and above implemented GPU switching via PRIME that works really well with nouveau. Sadly TLP has some issues with that, as soon as I would install TLP and reboot, system would run hot as the discrete nvidia GPU gets turned on permanently regardless of load.
I was looking for an alternate desperately to squeeze out the five hours I get with this laptop. Powertop solved that issue for me well. Keep up the good work.

3xOSC · 2014-03-04 17:01:21

From running powerdown manually:
[powerdown] cannot run x86_energy_perf_policy powersave

was the message I received. the difference in wattage consumption isn't that big of a difference. it still uses 16-19 watts. is that normal?
