+ | Here you can specify different results for pressing the specified laptop buttons. Note that not all laptops have dedicated buttons or function key combinations for sleep, suspend or hibernate. | ||

- | ! You can select the inactivity sleep action to be taken by the power manger when the system is idle for a interval of time set by you either on ac power or on battery power. Of course if you disable idle timeout those settings will have no effects. | + | |
- | ? Monitor sleep mode | + | |
- | ! DPMS sleep modes before switching off the monitor are either standby or suspend. They are technically different and provided for convenience. | + | |

+ | You can choose separate options to favor power saving (suspend), security (lock screen) or quick recovery (blank screen), depending on whether you are running on battery or plugged in. | ||
- | 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. | + | ==== Appearance ==== |
+ | By checking **Show notifications**, you enable informational popups for events like plugging and unplugging or low battery charge. | ||

+ | ==== 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. | ||
+ | |||

+ | ===== Display ===== | ||

+ | Check **Handle display power management** to allow Power Manager to manage the laptop' | ||
+ | |||
+ | The three options --- **Blank after**, **Put to sleep after** and **Switch off after** --- are theoretically in ascending order of power saving potential. However, not all laptop hardware is capable of making a distinction among these three modes and there is no direct indication on a laptop if the display is actually being turned off, suspended or just blanked. You may have to experiment to see which, if any, of these options yields the most power savings. | ||
+ | |||
+ | 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. | ||
