OpieUserManual/LightAndPower

= Light and Power =

The Light and Power settings application allows you to control the behaviour of the backlight and power saving features of your handheld device. These two items are related, as the brighter and longer the backlight is used, the faster the battery will be drained.

On Battery/AC
The first two tabs, "On Battery" and "On AC" are identical, and define the behaviour when the device is powered by batteries and connected to AC power respectively.

General settings
"Dim light after" sets the period of inactivity before the backlight will be dimmed. If the "Light off after" period is reached with no activity, the backlight will be turned off. Once the "Suspend after" period has elapsed, the device will be suspended (effectively powered down).

Backlight
The Backlight settings control the level of backlighting when the device is in normal use. You can either set a fixed backlight level, or (if your device has one) use the built-in light sensor to automatically adjust the light level (brighter when the sensor sees darkness, dimmer when it detects light).

Warnings
Opie can warn you when the battery in your device is running low. The "low power warning interval" is the time between warning messages when the low power level is reached. "very low battery warning at" and "critical power warning at" define the battery levels at which warning messages are shown.

If you wish, you may disable low power warnings by selecting "never" as the warning interval, however this is not recommended.
