Suspend on LID close

This article explains how to make your laptop go to Suspend when closing the LID.

This can be done via acpid with a hook in /etc/acpi/LID/00000080:

a) with pm-utils:

apk add pm-utils

Contents of /etc/acpi/LID/00000080

#!/bin/sh
exec pm-suspend

b) with this raw variant:

Contents of /etc/acpi/LID/00000080

#!/bin/sh
echo mem > /sys/power/state

Make the hook executable:

chmod +x /etc/acpi/LID/00000080

That should be it. To make sure that the acpid daemon is running, execute:

/etc/init.d/acpid start
