 This section explains in detail the possible configurations of the power manager running on a laptop computer. Please note that the configurations are different when the power manager is running on a desktop computer, for example you will not have LCD brightness, etc.\\  This section explains in detail the possible configurations of the power manager running on a laptop computer.

 +=== Brightness buttons ===
 If you want to control screen brightness with the laptop function keys, enable the **Handle display brightness keys** option. When this options is unchecked, the brightness keys are not handled by the Power Manager but directly by the kernel (if supported). If you want to control screen brightness with the laptop function keys, enable the **Handle display brightness keys** option. When this options is unchecked, the brightness keys are not handled by the Power Manager but directly by the kernel (if supported).
  
 +=== Hidden setting: Minimum brightness value ===
 +Depending on your hardware and setup you may want to specify a minimum brightness level. On some hardware the brightness handling allows the display to be turned off completely, which can be problematic if the user does not know how to turn up the brightness again. To enable this setting run this command ("5" being an example minimum value).
 +
 +<file bash>
 +xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/brightness-slider-min-level -s 5
 +</file>
 +
 +Alternatively you can also create the property via xfce4-settings-editor.
 +
 +Note: the minimum value should be a value relevant to your backlight interface as shown (on Linux) in the /sys/class/backlight/INTERFACE/* files. For example, a "max_brightness" value of 10,000 means that to set the minimum value at 10%, you would use 1,000 as the brightness-slider-min-level value.

 Power Manager does assume that each of these options will work at the hardware level and so it attempts to prevent an illogical configuration; e.g., a **Blank after** period greater than a **Put to sleep after** one. In a setup like the one shown in the screenshot above, if you drag the //On battery// **Put to sleep after** slider down to, say, 5 minutes, the **Blank after** slider will automatically move to one minute less. Likewise, if you try to reduce the **Switch off after** period to less than the other two, it will move the other two sliders to one minute and two minutes less, respectively. Power Manager does assume that each of these options will work at the hardware level and so it attempts to prevent an illogical configuration; e.g., a **Blank after** period greater than a **Put to sleep after** one.
