Power Management

Power Saving Mode

Phenomenon

 

 

Standby Mode

The Sleep indicator lights up

Waiting time specified by the System Standby value

 

or the operating system elapses without any system

 

activity.

 

Or

 

When the computer is about to enter Hibernation

 

mode (e.g. during a battery-low condition), but the

 

Hibernation file is invalid or not present.

 

 

 

Hibernation Mode

All power shuts off

When customized functions for power management

 

are set to Hibernation and the corresponding action is

 

taken.

 

 

 

Display Standby Mode

The display shuts off

Keyboard, built-in touchpad, and an external PS/2

 

pointing device are idle for a specified period.
