Heuristic Power Management

There is one necessary condition for the computer to enter Standby mode:

Heuristic Power Management must be set to [ENABLED].

There are four ways to enter Standby mode:

Pressing the Standby hot key Fn-F3

If the waiting time determined by the computer’s HPM unit elapses without any system activity

Closing the display cover

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

Note: If the computer beeps but does not enter Standby mode after pressing the Standby hot key, it means the operating system will not allow the computer to enter the power-saving mode.

The following signals indicate that the computer is in Standby mode:

The buzzer beeps

The Standby indicator lights

Warning: Unstored data is lost when you turn off the computer power in Standby mode or when the battery is drained.

To leave Standby mode and return to normal mode:

Press any key

Move the active pointing device (internal or external, PS/ 2 or serial)

Have the Resume Timer set and let it be matched

Open the display cover
