Laptop Mode Tools 1.46 (Default branch)
Laptop Mode Tools allows you to control various power management settings based on AC/battery power state. Among other things, it controls Linux's "Laptop Mode" feature that allows your hard drive to spin down for extended periods. It can also control CPU frequency scaling and screen blanking timeouts (both terminal and X). It supports automatic hibernation when battery is low. License: GNU General Public License (GPL) Changes:
This release has support for USB autosuspend, iwlagn wireless power management, Intel HDA audio power saving, and pm-utils integration. It adds a new polling mode for batteries that don't send ACPI events. Image

acpi_asus_wmi

ACPI_ASUS_WMI(4)					   BSD Kernel Interfaces Manual 					  ACPI_ASUS_WMI(4)

NAME

     acpi_asus_wmi -- Asus Laptop WMI Extras

SYNOPSIS

     To compile this driver into the kernel, place the following line in your kernel configuration file:

	   device acpi_asus_wmi

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   acpi_asus_wmi_load="YES"

DESCRIPTION

     The acpi_asus_wmi driver provides support for the extra WMI-controlled gadgets, such as hotkeys and leds, found on Asus laptops.  It allows
     one to use the sysctl(8) interface to manipulate the brightness of the LCD panel and keyboard backlight, power on/off different internal com-
     ponents, such as WiFi, Bluetooth, camera, cardreader, etc, read some sensors.  Hotkey events are passed to devd(8) for easy handling in
     userspace with the default configuration in /etc/devd/asus.conf.  Some hotkey events, such as keyboard backlight and touchpad control, are
     handled inside the driver.

SYSCTL VARIABLES

     The following sysctls are currently implemented:

     dev.acpi_asus_wmi.0.handle_keys
	     Specifies whether driver should handle some harwdare keys, such as keyboard backlight, internally.

     Number of other variables under the same sysctl branch are model-specific.

     Defaults for these variables can be set in sysctl.conf(5), which is parsed at boot-time.
