Heuristic Power Management
This computer has a built-in heuristic power management unit that monitors 
system activity. System activity refers to any activity involving one or more of 
the following devices: keyboard, mouse, floppy drive, hard disk, peripherals 
connected to the serial and parallel ports, and video memory. If no activity is 
detected for a period of time (called an inactivity time-out), the computer 
stops some or all of these devices in order to conserve energy.
This computer employs an innovative power management technique called 
Heuristic Power Management or HPM. HPM allows the computer to provide 
maximum power conservation and maximum performance at the same time.
Power management methods used by most computers are timer-based. You 
set inactivity time-out values for the display, hard disk, and other devices. The 
computer then sleeps when these time-outs elapse. The problem with this is 
that no two users are alike. Each of us has his or her own habits when using 
the computer, which makes timer-based power management ineffective.
With HPM, your computer manages its power according to the way you use 
your computer. This means the computer delivers maximum power when you 
need it, and saves power when you don’t need the maximum — all without 
your intervention. There are no timers to set, because the HPM system 
figures out everything for you.
We recommend you enable heuristic power management to prolong your 
battery life.
Power Management Modes
Display Standby Mode
Screen activity is determined by the keyboard, the built-in touchpad, and an 
external PS/2 pointing device. If these devices are idle for the period 
700SG-2.fm  Page 8  Monday, June 8, 1998  1:26 PM 
						

							Chapter 2 2-9
determined by the computer’s HPM unit, the display shuts off until you press 
a key or move the touchpad or external mouse. 
Automatic Dim Feature
The computer has a unique automatic dim power-saving feature. When the 
computer is using AC power and you disconnect the AC adapter from the 
computer, it automatically dims the LCD backlight to save power. If you 
reconnect AC power to the computer, it automatically adjusts the LCD 
backlight user setting to a brighter level.
Hard Disk Standby Mode
The hard disk enters standby mode when there are no disk read/write 
operations within the period of time determined by the HPM unit. In this state, 
the power supplied to the hard disk is reduced to a minimum. The hard disk 
returns to normal once the computer accesses it.
Peripheral Standby Modes
The peripheral connections in your computer also power down to save power 
if there is no activity within the period of time specified by the computer’s 
HPM unit for these devices. These include audio, serial ports, floppy drive 
and parallel port.
Standby Mode
The computer consumes very low power in Standby mode. Data remain 
intact in the system memory until the battery is drained.
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:
700SG-2.fm  Page 9  Monday, June 8, 1998  1:26 PM 
						

							2-10 EXTENSA 700/710 Service Guide
•  The buzzer beeps
•  The Standby indicator lights
Note: 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
•  Experience an incoming PC card modem event
Hibernation Mode
In Hibernation mode, all power shuts off (the computer does not consume 
any power). The computer saves all system information onto the hard disk 
before it enters Hibernation mode. Once you turn on the power, the computer 
restores this information and resumes where you left off upon leaving 
Hibernation mode.
There are two necessary conditions for the computer to enter Hibernation 
mode:
•  The Hibernation file created by PhDISK must be present and valid. See 
“PhDISK” on page 73.
•  Heuristic Power Management must be set to [ENABLED].
In this situation, there are four ways to enter Hibernation mode: 
•  Pressing the Hibernation hot key 
Fn-F4
•  If the waiting time determined by the computer’s HPM unit elapses 
without any system activity
•  If a battery low condition occurs and the Battery Low Suspend 
parameter in Setup is set to [ENABLED].
•  Invoked by the operating system power saving modes
Note: If the computer beeps but does not enter Hibernation mode after 
pressing the Hibernation hot key, it means the operating system will 
not allow the computer to enter the power-saving mode.
