How do I prevent immediate wake up from suspend and/or hibernation?

Question

For a few days, my Ubuntu 12.04 desktop computer has mysteriously been waking up immediately after going to suspend mode.

Since installation, my Ubuntu 12.10 laptop computer has also been resuming immediately after suspend and hibernation.

How to prevent those?

Answer 1

This problem was probably caused by strange USB signals. gedit /proc/acpi/wakeup showed me, that wakeup was enabled for USB0 and USB2.

sudo -s
echo USB0 > /proc/acpi/wakeup
echo USB2 > /proc/acpi/wakeup

switched them to disabled (checked by gedit /proc/acpi/wakeup again or refreshing the file-view), and after that, the computer stays in suspend like it should. :-)

Answer 2

I recently had the same symptom on Asus Zenbook Pro UX501 on Ubuntu 15.04. Bazon's exact fix did not work but Vladimir Rutsky's variation did. Specifically:

If running from the terminal cat /proc/acpi/wakeup shows the following lines

EHC1      S3    *enabled  pci:0000:00:xx.x
EHC2      S3    *enabled  pci:0000:00:xx.x
XHC       S3    *enabled  pci:0000:00:xx.x

(pci addresses may be different)

then toggle these three to disabled by issuing the following commands:

sudo -s
echo EHC1 > /proc/acpi/wakeup
echo EHC2 > /proc/acpi/wakeup
echo XHC > /proc/acpi/wakeup

If you know which device wake up your PC go to first step to follow the guide. If you don't, then open terminal and do:

cat /var/log/syslog

And find which device is waking your PC.

So now:

1. hit in terminal:

   grep . /sys/bus/usb/devices/*/power/wakeup
   

To list all usb ports that wakeup our pc.

sudo su

we have now root privillages.

2.I have 8 USB ports and in this example let's say that I want to disable usb8 ,so:

echo disabled > /sys/bus/usb/devices/usb8/power/wakeup

Go ahead and test it. Now that specific device in USB port 8 won't wake up the PC.

Next step, to make the change permanent after each boot:

3.

sudo nano /etc/rc.local

And we paste the command from step 2. In there (before the exit 0 of course).

That's it.

optional Only if after sleep/wakeup process the USB 8 device , in my example , revert back to enabled.

4. Write a udev rule too to execute the command after every boot,sleep,wake up.

Open a terminal and do:

lsusb

At your keyboard device id information the 4 first digits are the vendor id and the 4 next digits are the product id

Next do:

sudo nano /etc/udev/rules.d/10-wakeup.rules

Where "wakeup" enter your desired name of the script. Number 10 is the priority in case you have many other udev rules, the lower the number the 'rule' will be executed before the others.

Copy paste this and replace the vendor id and product id with your own wireless keyboard vendor id and product id.

ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="062a", ATTRS{idProduct}=="4101" RUN+="/bin/sh -c 'echo disabled > /sys/bus/usb/devices/usb8/power/wakeup'"

*usb8 for me is my wireless keyboard (you can also see that in the screenshot (Bus 008)), replace it with your own.

Ctrl + O to save , Ctrl + X to exit and reboot.

To make the fix permanent

(I am compiling the solutions provided by Bazon, Ilikerobots, and Pavlos Theodorou - together they address my specific issue)

To fix the issue permanently, whether it is a USB port waking up the system or something else:

1. Find out what is allowed to wake up your system:

gedit /proc/acpi/wakeup

You might get these or similar lines:

EHC1 S3 *enabled pci:0000:00:xx.x

EHC2 S3 *enabled pci:0000:00:xx.x

XHC S3 *enabled pci:0000:00:xx.x

Then open:

sudo gedit /etc/rc.local

and add these lines (or similar, depending on the results above) before exit 0

echo EHC1 > /proc/acpi/wakeup

echo EHC2 > /proc/acpi/wakeup

echo XHC > /proc/acpi/wakeup

Answer 5

This is what worked for me on my Mac Book Pro 2015

I added the following to /lib/systemd/system-sleep/wakeup_disable

#!/bin/sh

# /lib/systemd/system-sleep/wakeup_disable
#
# Avoids that system wakes up immediately after suspend or hibernate
#
# Tested on MacBookPro 2015

case $1 in
  pre)
    if grep -qE '^XHC1.*enabled' /proc/acpi/wakeup; then
        echo XHC1 > /proc/acpi/wakeup
    fi
    if grep -qE '^LID0.*enabled' /proc/acpi/wakeup; then
        echo LID0 > /proc/acpi/wakeup
    fi
    ;;
esac

Note this will prevent waking up via the lid opening and via keyboard/mouse/USB device you have to push the power button.

Answer 6

I solved this problem in a simple way, writing the following lines in /etc/rc.local to enable only wakeup by PS2 keyboard:

for d in `cat /proc/acpi/wakeup |grep enabled|grep -v PS2K|cut -b -4`; do
    echo $d >/proc/acpi/wakeup ; 
done

When Linux boots, it executes the /etc/rc.local file disabling wakeup by USB or other devices.
