This article explains how to make your laptop go to Suspend when closing the LID.
acpid2
acpid2 (provided by package acpid) is a flexible and extensible daemon with Netlink support for delivering ACPI events. The default handler script (/etc/acpi/handler.sh) installed with the package provides support for suspend on LID close out of the box. We recommend installing zzz along with acpid to get support for pre/post suspend hooks etc.
- Install acpid and zzz:
# apk add acpid zzz
- Enable and start the acpid daemon:
# rc-update add acpid && rc-service acpid start
Busybox acpid
This can be done via Busybox acpid with a hook in /etc/acpi/LID/00000080:
- with zzz:
# apk add zzz
Contents of /etc/acpi/LID/00000080
#!/bin/sh exec zzz - or with pm-utils:
# apk add pm-utils
Contents of /etc/acpi/LID/00000080
#!/bin/sh exec pm-suspend - or with 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:
# rc-service acoud start
