Advanced Settings Screen • This screen allows you to set which devices to power on or off for each profile. It also provides other settings to help you save power. You can access this screen by clicking the Advanced button on the Main Settings Screen. • Of special note on the Advanced Settings screen are the following. Devices - When switching profiles, automatically power on/off specified devices If checked, devices specified in the list to the right will automatically be powered on or off as specified whenever the power profile is switched (either by the user, or if changing from plugged-in to battery). This list allows you to select which components of the system are powered on for each profile. Un-checking a device will power it off and render it temporarily unusable by the system. Powering off devices that are not being used can greatly increase your battery life. Some devices, such as radios and USB, can draw considerable power. Notes: 1) The power state of the devices you specify here will override any device enable/disable settings in Windows Device Manager. 2) This feature may be disabled on some platforms if stealth mode is enabled in BIOS setup. 2009.02.19.GD8000 Copyright © 2008-2009 General Dynamics Itronix 22
CPU Power Savings Specifies whether or not to use Aggressive power savings. Setting CPU Dynamic Throttle Policy Fan Throttle Tolerance*** Aggressive checked Aggressive not checked ADAPTIVE* (Plugged In) DEGRADE** (battery) ADAPTIVE* (Plugged In & battery) 0% (Plugged In & battery) 100% (Plugged In) 80% (battery) * ADAPTIVE - Attempts to match the performance of the processor to the current demand. This policy will use both high and low voltage and frequency states. This policy will lower the performance of the processor to the lowest voltage available whenever there is insufficient demand to justify a higher voltage. This policy will engage processor clock throttling if the C3 state is not being utilized, and in response to thermal events. ** DEGRADE - Does not allow the processor to use any high voltage performance states. This policy will engage processor clock throttling when the battery is below a certain threshold, if the C3 state is not being utilized, or in response to thermal events. *** Lower limit that the processor may be throttled down to prior to turning on system fans in response to a thermal event (%). For example, if this value is set to 80% then the processor cannot throttle down below 80% before turning on the fan. The fan uses more power while cooling the CPU, throttling saves power while cooling the CPU. Thermal Management Can set to Aggressive, Normal or Moderate. The CPU will throttle sooner when on Aggressive.
