Laptop does not suspend when lid is closed

I'm a new Ubuntu 13.10 user. Closing the lid of my laptop does not result in the computer entering suspend mode, meaning each time I close my lid without manually suspending the computer the battery dies.

The proper settings are set in Power Management -- suspend the laptop on lid close for both AC and DC, but these do not have an effect on actual behavior.

It looks like this is a common problem for many users as far back as Ubuntu 11 -- the only solution I could find is the below. However, as a new linux user I'm not aware of how to actually execute the instructions. If someone could provide additional detail that would be tremendously helpful.

Thanks in advance.

/etc/acpi/events/lidbtn triggers /etc/acpi/lid.sh which triggers

 /etc/acpi/local/lid.sh.post at the end of the script.

 /etc/acpi/local/* allows you to add your own config (e.g. required for

 wmii).



 generate /etc/acpi/local/lid.sh.post

 make it executable and add:



 #!/bin/bash

 grep -q closed /proc/acpi/button/lid/*/state

 if [ $? = 0 ]

 then

 /usr/sbin/pm-suspend

 fi



 wmii will now go to suspend mode when closing the lid. It'll

 automatically wake up when opening the lid.

    #!/bin/bash



    load=$(cat /sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0A:00/power_supply/BAT0/capacity)

    min_load=20

    if [ $load <= min_load ]; then

        pm-suspend

    fi

(Note that # before a command indicates that it should be run by the superuser, so replace the # with sudo.)

Open logind.conf as root: # vim /etc/systemd/logind.conf and remove the # before HandleLidSwitch=suspend. You can also change the option suspend to hibernate or poweroff

Fix from Launchpad Bug #863834, comment #30:

Open a terminal: Ctrl + Alt + t

# mkdir /etc/acpi/local

# vim /etc/acpi/local/lid.sh.post

Copy this short script:

 #!/bin/bash

 if grep -q closed /proc/acpi/button/lid/*/state

 then

     /usr/sbin/pm-suspend

 fi

... and paste it into vim by typing: "+p

Save by typing ZZ (in capitals)

# chmod 755 /etc/acpi/local/lid.sh.post (so it works even when power management is handled under the logged-in user instead of root)
