+ | ==== System Power Saving ==== | ||
+ | * **System sleep mode:** --- Specifies the type of power saving mode to enter after a period of inactivity. On some distributions the only option available is **Suspend**. | ||
+ | * **Put system to sleep when inactive for** --- Sets the duration of inactivity before the specified sleep mode is entered. The minimum duration you can set with the slider is 15 minutes. | ||
+ | ==== Critical power ==== | ||
+ | * **Critical battery power level:** --- All batteries behave differently when it comes to discharge behavior. For some, it may take hours to go from 100% to 10% but then just minutes to discharge completely from 10%. This setting allows you to configure a higher or lower threshold before taking some kind of action for a low battery level. The range is from 1% to 20%. | ||
+ | * **On critical battery power:** --- Determines the action to take when the battery reaches the user-configured critical charge threshold. | ||
+ | ==== Security ==== | ||

- | ? Power is critical | + | |
- | ! With this option you can specify the action taken by the power manager in case the system is running on low power. If this option is disabled and the computer is running on low battery power, the power manager will display a warning message. | + | |
- | ? Prefer power savings over performance | + | |
- | ! This is the power profile when running on battery. With this option your battery will last more when running on battery power. Enabling this option is always a good idea. | + | |

- | ===== Hidden Options ===== | + | |
- | + | ||
- | Hidden options are the options that in normal situations one should not be changed, but these options are provided in case of misbehaviour of the backend that the power manager is relying on. | + | |
- | + | ||
- | Since xfce4-power-manager relies on xfconf to store and retreive configurations, | + | |
- | + | ||
- | ? LCD Brightness | + | |
- | ! The xfce4-power-manager detects brightness key events and interacts with the backend | + | |
- | ! < | + | |
- | ? Disabling Brightness popup | + | |
- | ! If you want for some reason to disable the brightness popup indicator (the one which popup to display the brightness level), just run the following command in your terminal. | + | |
- | ! < | + | |
+ | Power Manager does assume that each of these options will work at the hardware level and so it attempts to prevent an illogical configuration; | ||
+ | ==== Brightness reduction ==== | ||
+ | These settings allow you to be more or less aggressive with screen brightness reduction depending on whether the laptop is running on battery or plugged in. | ||
