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.

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:
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 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.
2-10
EXTENSA 700/710 Service Guide
To exit Hibernation mode, press the power switch. The computer also resumes from Hibernation mode if the resume timer is set and matched. The computer also resumes via the network if the Wake On LAN parameter is enabled.
Note: Do not change any devices (such as add memory or swap hard disks) when the computer is in Hibernation mode.

Advanced Power Management
This computer supports the APM standard designed to further reduce power consumption. APM is a power-management approach defined jointly by Microsoft and Intel. An increasing number of software packages support APM to take advantage of its power-saving features and allows greater system availability without degrading performance. For more information about APM under Windows 95, refer to your Windows 95 user's manual.
Note: If you enable heuristic power management in Setup without APM installed and enabled (true by default), the system time and date do not display the correct settings after the computer returns to normal operation from Standby or Hibernation mode. To update the time and date, reboot the computer. APM should be enabled to avoid this problem. Advanced Power Management greatly prolongs battery life. Use APM whenever possible.

PhDISK
The PhDISK utility allows your computer to enter hibernation mode. Before entering hibernation mode, your computer saves all necessary computer information into a file or partition created by PhDISK, then shuts off power to all system components. On the next startup, the computer reloads the information from the PhDISK file or partition and resumes from where you left off.
Note: By default, this program is automatically loaded and set up on your computer so you do not need to run this program by yourself. You only need to run this if you upgrade your memory. You can find PhDISK in the \windows\command\ directory.
The program accepts the following parameters: Syntax PHDISK [options] where options:
· /CREATE (/FILE or /PARTITION) creates the hibernation file or
partition
· /DELETE (/FILE or /PARTITION) deletes the hibernation file or partition · /INFO displays information on the hibernation file or partition · /REFORMAT PARTITION reformats the existing hibernation file or
partition Note: The Hibernation file is a hidden file named SAVE2DSK.BIN; DO NOT delete or alter this file in any way except by using the PHDISK utility. Improper deletion or alteration of this file could cause you to lose all access to your computer. Example:
· C:/phdisk/create/file · C:/phdisk/create/partition

Power System Checkout
To verify the symptom of the problem, power on the computer using each of the following power sources: 1. Remove the battery pack and diskette drive. 2. Connect the AC Adapter and check that power is supplied. 3. Disconnect the AC Adapter and install the charged battery pack; then check that power is supplied by the battery pack. If you suspect a power problem, see the appropriate power supply checkout in the following list:
· "Checking the AC Adapter" · "Checking Operational Charging" · "Checking the Battery Pack"
Checking the AC Adapter:
· You are here because the computer fails only when the AC Adapter is
used:
· If the power problem occurs only when the port replicator is used,
replace the port replicator.
· If the power-on indicator does not turn on, check the power cord of the
AC Adapter for correct continuity and installation.
· If the operational charge does not work, go to "Checking Operational
Charging." 1. Unplug the AC Adapter cable from the computer and measure the output voltage at the plug of the AC Adapter cable. See the following figure
Chapter 4

:
Pin 1 2
Voltage (Vdc) +19 to +20.5 Ground
If the voltage is not correct, replace the AC Adapter. If the voltage is within the range, do the following:
· Replace the Main board. · If the problem is not corrected, go to "Undetermined Problems". · If the voltage is not correct, go to the next step. Note: An audible noise from the AC Adapter does not always indicate a defect.
Checking Operational Charging: To check operational charging, use a discharged battery pack or a battery pack that has less than 50% of the total power remaining when installed in the computer. Perform operational charging. If the battery status indicator does not turn on, remove the battery pack and let it return to room temperature. Reinstall the battery pack. If the charge indicator still does not turn on, replace the battery pack. If the charge indicator still does not turn on, replace the Main board. Then reinstall the battery pack. If the reinstalled battery pack is not charged, go to the next section.
Checking the Battery Pack:
Battery charging will not start until the Fuel-Gauge shows that less than 95% of the total power remains; with this condition the battery pack can charge to 100% of its capacity. This protects the battery pack from being overcharged or having a shortened life. Do the following:

EXTENSA 700/710 Service Guide
1. Power off the computer. 2. Remove the battery pack and measure the voltage between battery terminals 1 (+) and 7. See the following figure:
If the voltage is still less than +10.0 Vdc after recharging, replace the battery.
TouchPad Checkout
If the TouchPad does not work, check the configuration in the ThinkPad BIOS program. If the configuration of the TouchPad is disabled, select Enable to enable it. If this does not correct the TouchPad problem, continue with the following. After you use the TouchPad, the pointer drifts on the screen for a short time. This self-acting pointer movement can occur when a slight, steady pressure is applied to the TouchPad pointer. This symptom is not a hardware problem. No service actions are necessary if the pointer movement stops in a short period of time. If a click button problem or the pointing stick problem occurs, do the following: 1. Boot from the diagnostics diskette and start the PQA program (please refer to "Running PQA Diagnostics Program". 2. Go to the diagnostic Pointing Dev. in the test items. 3. Press F2 in the test items. 4. Follow the instructions in the message window. If either the pointing stick or the click button do not work, do the following actions one at a time to correct the problem. Do not replace a nondefective Spare Part: 1.

Intermittent Problems
Intermittent system hang problems can be caused by a variety of reasons that have nothing to do with a hardware defect, such as: cosmic radiation,

electrostatic discharge, or software errors. Spare Part replacement should be considered only when a recurring problem exists. When analyzing an intermittent problem, do the following: 1. Run the advanced diagnostic test for the Main board in loop mode at least 10 times. 2. If no error is detected, do not replace any Spare Part. 3. If any error is detected, replace the Spare Part shown by the Spare Part code. Rerun the test to verify that no more errors exist.
Undetermined Problems
You are here because the diagnostic tests did not identify which adapter or device failed, installed devices are incorrect, a short circuit is suspected, or the system is inoperative. Follow these procedures to isolate the failing Spare Part (do not isolate nondefective Spare Part).
Note: Verify that all attached devices are supported by the computer. Note: Verify that the power supply being used at the time of the failure is operating correctly. (See "Power Systems Checkout"): 1. Power off the computer. 2. Visually check them for damage. If any problems are found, replace the Spare Part. 3. Remove or disconnect all of the following devices:
a. Non-Acer devices b. Devices attached to the port replicator c. Printer, mouse, and other external devices d. Battery pack e. Hard disk drive f. DIMM g. CD-ROM h. Diskette drive i. PC Cards
4. Power on the computer. 5. Determine if the problem has changed. 6. If the problem does not recur, reconnect the removed devices one at a time until you find the failing Spare Part. 7. If the problem remains, replace the following Spare Part one at a time. Do not replace a nondefective Spare Part:
a. Main board b. LCD assembly c. CPU card

Setting LCD Panel ID
There is an EEPROM in the inverter which stores its supported LCD type ID code. If you replace a LCD with one of a different brand or use a new inverter, the ID information in the inverter EEPROM should be updated. Follow the steps blew to see the LCD Panel ID: 1. Follow the instruction on screen to read current or to set new LCD Panel ID code. Note: When you set a new LCD Panel ID and the new LCD is not yet enabled (to function), so connect an external CRT to see the program execution process. Note: Make sure the new ID code you choose corresponds with the LCD brand and type. If you write a wrong ID into inverter, just reboot and re-execute the program and input the correct ID code. 2. Restart computer - the new LCD should work normally. Note: If LCD cannot display after change ID code, make sure you write the correct ID code, or try reseating the LCD FPC cable connectors.
Setting Thermal Sensor Utility
The system is equipped with sensors to protect against system overheating. By setting System and processor thermal thresholds, the system can turn on the cooling fan or shut down automatically when temperatures reach the defined threshold parameters.
