# Power management ## ACPI During installation Busybox's `acpid` has already been replaced by the regular `acpid` which means that it has to be configured in `/etc/acpi/handler.sh`. The default configuration works but by default will not suspend the device if an AC adapter is connected even if the lid is closed. Therefore it is recommended in `button/lid:*:close:*` to change it to: ``` #power-supply-ac || suspend suspend ``` ## TLP To optimise device battery it is recommended to install `tlp` and activate its service: ``` # apk add tlp # rc-update add tlp default ``` `tlp` can be configured in `/etc/tlp.d` but the default configuration already works.
