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 t ime-out valu es for the d isplay, hard disk, a nd other de vices. Th e
computer then "sleeps " when these ti me-outs elaps e. 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 th e com put er del iver s ma ximum pow er wh en yo u
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
2-8 EXTENSA 700/710 Servic e Gu ide
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 un iqu e "a uto mat ic dim " po w er-s av ing feat ure. 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 t he perio d of time dete rmi ned by the HP M unit. In thi s stat e,
the power supplied to the hard disk is reduced to a minimum. The hard disk
returns to n ormal once the computer accesses it.
Peripheral Standby Modes
The peripheral co nnecti ons i n your comp uter als o pow er do wn to sa ve 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
•
If the waiting time determined by the computer’s HPM unit elapses
Fn-F3
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 ho t key, it means the operating s ystem wi ll not
allow the computer to enter the power-saving mode.
The following signals indicate that the computer is in Standby mode:
Chapter 2 2-9
•
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 Hibernatio n mode . Once yo u 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 creat ed by PhD ISK must b e present and vali d. 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
•
If the waiting time determined by the computer’s HPM unit elapses
Fn-F4
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 Hibernatio n hot key, it means the oper ating sy stem wi ll
not allow the computer to enter the power-saving mode.
