Power Saving Modes
Power Savings Options
Your Extensa system offers several options for you to extend your battery life while you are not actively using your computer. These options turn off different sections of the computer that are not currently being used.
These options are listed in the POWER
MANAGEMENT page of the System Setup screen
(accessed via Fn+F1 anytime or F2 during boot up). They are described below:
Power Management
Standby Timeout
5V Suspend Timeout
This option sets when you want the time outs to take effect.
ALWAYS: Enables the time out settings regardless of whether the computer is on AC or battery power.
BATTERY ONLY: Only enables the time outs when the computer is running off the battery power.
DISABLE: Disables all power time out settings.
The length of time the computer needs to be idle before the computer enters Standby mode.
The length of time the computer needs to be idle before the computer enters 5V Suspend.
1-9
Power Saving Modes
0V Suspend Timeout
Hard Disk Timeout
Display Timeout
The length of time the computer needs to be idle before the computer enters 0V Suspend.
The length of time the computer needs to be idle before the hard disk drive’s motor is turned off.
The length of time the computer needs to be idle before the display back light is turned off.
The computer will not enter any of the power management time-out modes if the hard disk drive, floppy disk drive (or CD-ROM drive in the optional MPB docking module) is active.
Note: If the “Auto Insert Notification” option is enabled in the CD ROM setting, the computer will not time out on any of the power management time-outs because Windows 95 will constantly be looking for a new CD to be inserted. This option is set to a default of DISABLED by Texas Instruments.
1-10
0V Suspend Mode
0V Suspend mode saves the exact spot you are at on your computer, then shuts off all power without losing any data.
Power Saving Modes
In 0V Suspend mode, the computer saves the current computer state onto your hard disk drive then shuts off. When you turn the computer on again, it restores the computer to the saved state within about a minute.
Press the 0V Suspend hot key (Fn+F2) to enter 0V Suspend mode. To resume normal operation, press the power switch. 0V Suspend mode occurs automatically if the 0 VOLT SUSPEND
TIMEOUT parameter in Setup is enabled and
times out or if the BATTERY LOW SUSPEND option is enabled and your battery runs down to a critically low level.
Note: Your computer will not enter 0V Suspend mode if the 0V Suspend file is missing or is the incorrect size. Refer to Chapter 2, the Adding Memory section for further information.
5V Suspend Mode
5V Suspend mode consumes very little power when you are not using your computer, yet still resumes quickly. With a fully charged battery, your computer can remain in 5V Suspend mode for days.
Caution: If your computer loses power while
!
in 5V Suspend, you will lose all of your unsaved data.
1-11
Power Saving Modes
In 5V Suspend mode, the computer saves the current computer state onto your system memory then shuts off power to most of the devices except the system memory. The standby indicator flashes to indicate the computer is in 5V Suspend mode. When the computer resumes from 5V Suspend mode, it restores the computer to the saved state.
Press the 5V Suspend hot key (Fn+F3) or close the display cover to enter 5V Suspend mode. The computer also enters 5V Suspend mode if the 5V SUSPEND TIMEOUT parameter in Setup is enabled and times out.
To resume normal operation, press any key on the internal keyboard or press the power switch. The computer also resumes from 5V Suspend if the RESUME ON MODEM RING or RESUME ON ALARM options are enabled in the System Setup and a modem ring or alarm occurs.
1-12
Note: It takes the computer a few seconds to
resume from a 5V Suspend. You may see the screen blank a few times while the computer restores all of the system states.
Standby Mode
Standby mode saves some computer power by turning off a few of the unused devices and still allows you to resume your work instantly. The standby indicator lights up in Standby mode.
Power Saving Modes
Press the Standby hot key (Fn+F4) to enter Standby mode. The computer also enters Standby mode if the STANDBY TIMEOUT parameter in Setup is enabled and times out.
To resume from Standby mode, press any key or touch the touchpad. The computer also resumes from Standby if the RESUME ON MODEM
RING or RESUME ON ALARM options are enabled in
the System Setup and a modem ring or alarm occurs.
Note: The computer acts on the key you press. To prevent unintended results, press a non­printing character such as Shift, Ctrl or Alt.
Refer to Chapter 3, Responding to Low Battery Conditions, for more ideas on how to conserve power.

3-1
Guidelines for Battery Use
Caution: Never dispose of exhausted batteries
!
in a fire. Observe applicable environmental regulations and recycle if possible.
The battery should be handled carefully to ensure maximum life. In particular:
q Do not drop the battery or subject it to
shocks. q Do not expose the battery to direct sunlight,
moisture, chemicals, or temperature
extremes. q Do not short the battery leads or insert the
battery upside down. q Charge the battery after several days of
disuse to keep it fully charged. If your
computer is idle for an extended period of
time, charge the battery every three (3)
months. q Never use the battery to power other
products. q The battery pack has thermal fuses to
prevent unsafe computer operation. The
computer may not operate on battery power
after storage in a very warm place until the
thermal fuses cool. q This computer is designed to only work with
the smart battery packs. Only use the
authorized packs with this computer.
3-2
Switching to Battery Power
To use battery power, install batteries as described in Installing the Battery Pack later in this section.
As long as the battery has charge remaining, you can switch to battery power by removing the connection to the AC adapter, even if the computer is already on.
Your computer switches back to AC power when an AC adapter is plugged into the computer, even if the computer is already on.
To maintain a full charge on your battery, always reconnect the computer to the AC adapter whenever possible.
3-3
Responding to Low Battery Conditions
There are two battery low stages in this computer. When the battery capacity reaches 7% (about 10 minutes remaining), the computer enters the first stage of battery-low warning. At this time the battery-low LED, found on the LCD center hinge, flashes and an audible warning sounds. You can keep the battery audible warning from ever sounding by disabling the
BATTERY LOW WARNING BEEP option in Setup. If the BATTERY LOW SUSPEND option is enabled in Setup,
the computer enters 0V Suspend mode after 1 minute of system inactivity if no AC is plugged in.
When the battery capacity reaches 4% capacity (about 2 minutes remaining), a second audible warning sounds. If the BATTERY LOW SUSPEND option is enabled in Setup, the computer enters 0V Suspend mode after 10 seconds of system inactivity if no AC is plugged in.
3-4
The following actions can maximize the time before the battery is depleted and minimize the effect of losing power:
q Set the screen brightness and contrast
control to the lowest possible setting. q Save your work in progress to minimize the
danger of losing data. q If you are using a RAM disk, save the
contents of the RAM disk to the hard disk
drive.
Responding to
Low Battery Conditions
q Whenever you are not actively using the
computer, press the 5V Suspend hot key
(Fn+F3) or Standby hot key (Fn+F4) to put
the computer into 5V Suspend mode or
Standby mode respectively. q Turn off the computer or put it in 0V
Suspend mode (Fn+F2) if it does not need to
be active. The computer does not consume
power in 0V Suspend mode. Once your computer enters 0V Suspend mode,
you can install a fully-charged battery and then resume from 0V Suspend mode. AC power can be connected at any time.
3-5
Recharging the Battery
Caution: Never recharge the battery differently
!
from the procedure described in this manual.
The following procedure is acceptable under most circumstances:
1. Install the battery pack into your computer (if
not already installed).
2. Connect the AC adapter. To maintain a full charge, leave the computer
connected to the AC adapter except when transporting the computer.
The battery is charged whether the computer is on or off, as long as the AC is plugged in. However, the battery charges faster when the computer is off.
3-6
Calibrating the Battery
The Extensa system uses a smart Lithium-Ion (Li-Ion) rechargeable battery. Your new smart batteries keep extremely accurate track of the battery capacity. However, all rechargeable batteries lose capacity over time due to different charging and discharging conditions, as well as general wear and usage. In order to keep accurate track of the true capacity, the battery must be calibrated every once in awhile.
Caution: If the battery loses track of the true
!
capacity, it will not correctly predict low battery conditions and can cause the system to shut off prematurely and without warning.
The battery itself keeps track of when it needs to be calibrated. The computer will post a warning when you boot up the system when it is time to re-calibrate. To calibrate the battery, you must first fully charge the battery, then fully discharge the battery.
Use the following instructions to calibrate your battery.
1. Charge the battery by leaving the battery in
the computer and having the AC adapter plugged into the computer. The battery is fully charged when the charging LED turns off.
2. Disconnect the AC adapter from the
computer.
3-7

Overview of Mobility
Disconnecting from the Desktop
No matter where you are taking your computer, you need to disconnect it from your desktop accessories.
Moving Around
“Moving around” refers to using your computer at different locations within the same building, for example, taking it with you to meetings.
Taking the Computer Home
Since you are taking the computer to the same place every night, you can save yourself time and effort by setting up a home desktop.
6-2
Traveling with the Computer
The farther you get away from home or office, the more important it is to bring the necessary equipment and supplies with you.
Traveling Internationally with the Computer
Traveling internationally with your computer creates special concerns you need to address before you leave the country.
Disconnecting from the Desktop
Follow these steps to disconnect your computer from external accessories.
1. Save your work in progress.
2. Shut down the operating system.
3. Turn off the computer.
4. Disconnect the cord from the AC adapter.
5. Disconnect the keyboard, pointing device,
printer, external monitor, and other external devices.
If your external devices are connected to an
optional docking module, just disconnect the notebook from the docking module. You do not need to disconnect the external devices from the docking module.
6. Disconnect the Kensington lock if you are using one to secure the computer.
6-3
Moving Around
Preparing the Computer
Before moving the computer, press Fn+F3 to place it in 5V Suspend mode. After placing the computer in 5V Suspend mode, close and latch the cover. You can now safely take the computer anywhere you go within the building.
To bring the computer out of 5V Suspend mode, press a key or touch the touchpad.
What To Bring to Short Meetings
A fully charged battery runs the computer for 2­3 hours under most circumstances. If your meeting is shorter than that, you probably do not need to bring anything with you other than the computer.
6-4
What To Bring to Long Meetings
If your meeting will last longer than 3 hours or if your battery is not fully charged, you may want to bring the AC adapter with you to plug in your computer in the meeting room.
If the meeting room does not have an electrical outlet, reduce the drain on the battery by putting the computer in 5V Suspend mode (Fn+F3) or Standby mode (Fn+F4) whenever you are not actively using the computer.
Taking the Computer Home
Preparing the Computer
After disconnecting the computer from your desktop, follow these steps to prepare the computer for the trip home.
1. Remove all media from the drives. Failure to remove the media can damage the drive head.
