Ergonomics Information

This is important information to read before using your ThinkPad
computer in the virtual office.

Working in the Virtual Office may mean adapting to frequent
changes in your environment. Following some simple “rules of the
road” will make things easier and bring you the maximum benefits of
your ThinkPad computer. Keeping in mind such basics as good
lighting and proper seating, for example, can go a long way in
helping you enhance your performance and achieve greater comfort
wherever you are.

Note: The example shown here of someone in a traditional setting. Even
when not in such a setting, you can follow many of these tips. Develop
good habits and they will serve you well.

ix

Chair

Use a chair that gives you
good back support.

Arms

Keep your forearms, wrists,
and hands in a relaxed and
neutral position. Don’t
pound the keys; type with a
soft touch.

Thighs

Keep your thighs parallel to
the floor and your feet flat on
the floor or on a footrest.

What if I am traveling?

It may not be possible to observe the best ergonomic practices when
you are using the ThinkPad computer while on the move or in a
“casual” setting, such as the seashore or on a mountaintop.
Sometimes, your lap may be the only “desk” around. Regardless of
the setting, try to observe as many of the tips for proper usage as
possible. Sitting properly and using adequate lighting, for example,
will help you maintain desirable comfort and performance levels.

Head

Keep your head in a
comfortable and vertical
position.

View

Maintain a comfortable
viewing distance of 20-30
inches.

Display

Position the display to avoid
glare or reflections from
overhead lighting or outside
sources of light.
Keep the display screen
clean and set the contrast
and brightness to levels that
allow you to see the screen
clearly.

Questions about vision?

IBM’s visual display screens are designed to meet the highest
standards and to provide you with clear, crisp images and large,
bright displays that are easy to see, yet easy on the eyes. Of
course, any concentrated and sustained visual activity can be tiring.
If you have questions on eye fatigue or visual discomfort, consult a
vision care specialist for advice.

Attention:

Always use the AC Adapter certified
by IBM in the country where you will
be using the computer. Operating the
computer with an incorrect AC Adapter
can cause damage to the battery pack
and to the computer.

You can use your computer almost anywhere: at home, in the office,
or on the road. Different power sources can be used for different
conditions: the AC Adapter, or the battery pack. When you have
access to an electrical outlet, you can use the AC Adapter for
continuous power. Otherwise, you can use the battery pack.

AC Adapter

The AC Adapter is an alternating current (ac) to direct current (dc)
converter that supplies power for the computer. The AC Adapter
also charges the battery pack when it is installed in the computer.

The input voltage is 100 — 240 V ac, 50/60 Hz. Refer to the label
on your AC Adapter for the input voltage, and make sure you use
the AC Adapter with the stated input voltage.

Do not attempt to open the AC Adapter case. The AC Adapter is
permanently sealed and cannot be repaired.

DANGER

Providing Power

Battery Pack

The battery pack is an internal power source for the computer when
no electrical outlets are available. The battery pack can be
recharged with the AC Adapter.

The approximate operating time of the computer with a fully charged
battery pack depends on the applications used, whether power
management is used, the frequency of keystrokes, and the
configuration of the system.

To ensure the longest possible battery life, in terms of both length of
use per charge and number of charge and discharge cycles before
wearing out, please observe these guidelines:

• Battery packs shipped from the factory are in an almost­discharged state, so you must charge them fully before use.

• When charging, always charge the battery pack fully. Even if
you only need to run on battery power for a fraction of the
battery’s capacity, you should not try to give the battery a partial
charge.

• Normal charging causes the battery pack to heat up slightly. Let
it cool for 15 minutes before you use it.

• Immediately after the battery pack has been drained of power, it
may be warm to the touch. This is normal. However it should
be set aside to cool for 15 minutes before recharging.

Operating the TrackPoint III Pointing Device

Operating the TrackPoint III Pointing Device

Note:

No other software is required for the
TrackPoint III; it works with the PS/2
mouse driver.

The keyboard contains a unique cursor-pointing device called
TrackPoint III. Pointing, selecting, and dragging all become part of
a single process, so you need not move your fingers from their
normal typing position.

The TrackPoint III consists of a stick on the keyboard and a pair
of click buttons in front of the keyboard. The motion of the
cursor is controlled by pressure applied to the stick in any direction
within the plane of the keyboard; the stick does not move. The
speed at which the cursor moves corresponds to the amount of
pressure on the stick. The click buttons are similar in function to
those on other pointing devices; what they do depends on the
software that is used.

2-10 IBM ThinkPad 310E/310ED: User’s Guide

Operating the TrackPoint III

If you are new to the TrackPoint III, these instructions will help you
get started.

Note:

Remember that the stick does not
move.

Note:

The mouse pointer may drift. This is
not a defect. Do not use the
TrackPoint III until the pointer stops
moving.

Note:

Either thumb can be used.

1 Place your hands in the typing position and press gently with

either index finger in the direction in which you want the cursor
to move.

Pressing the stick away from you moves the cursor up the
screen; pressing it toward you moves the cursor down the
screen.

2 Use the click buttons to select and drag as required by your

software, in the same way as for any other pointing device.

Using the Computer LCD or the External Monitor

This section provides information about using the computer display
and an external monitor. It also provides tips to consider when using
DOS applications.

The LCD in your computer displays computer output with SVGA
(800-by-600 resolution). On some models, thin-film-transistor (TFT)
technology is used, providing up to 65,536 colors. On some models,
dual-scan super twisted nematic (DSTN) technology is used,
providing up to 256 colors.

Display Output Type

To attach an external monitor:

+ Page 3-16

When you attach an external monitor that supports higher resolution
than VGA mode, you can get a maximum of 1024x768 video
resolution.

To display your computer output on an external monitor, you need to
set the appropriate display output type (where to display the
computer output). You can select one of the following display out
types:

• LCD: The computer output is displayed only on the LCD of the
computer.

• CRT: The computer output is displayed only on the attached
external monitor.

If no external monitor is attached to the computer and the display
output type is set to CRT, the output is displayed on the LCD.

• Both: The computer output is displayed on both the LCD and the
external monitor.

an external monitor that supports only
VGA mode (640-by-480 resolution).
Otherwise, the external monitor
screen will be scrambled and the
output will not be displayed, or the
screen might be damaged.

Note:

Refer to the specifications for your
external monitor to determine its
supported resolutions and refresh
rates.

To attach an external monitor:

1 Change the display output type to CRT or Both. (See “Display

Charging the Battery Pack

Charging the Battery Pack

Note:

For more information on maintaining
your battery packs, see page 4-4.

Charging with the AC Adapter

Note:

Battery packs shipped from the
factory are in an almost-discharged
state, so you must charge them fully
before use.

If the battery pack is new or has not been used for a long period of
time, it does not reach full charge with only one charging. This is
normal. When used regularly (at least once per week) and properly
(as described on page 4-4), the battery pack will work its way back
up to full capacity within five or six charge and discharge cycles.

The battery pack can be charged with the AC Adapter. You must
charge the battery pack in any of the following situations:

• A new battery pack was purchased.

• The battery status indicator (orange) is blinking, and the

computer beeps four times.

• The battery status indicator (orange) blinks for less than 1
minute.

The following table shows the approximate charging times for the
battery pack:

Conditions Charging Time

Operational charging 6 to 8 hours
Power-off charging 2 hours

4-2 IBM ThinkPad 310E/310ED: User’s Guide

Charging the Battery Pack

The following procedure describes how to recharge the battery pack
with the AC Adapter when the computer is turned off.

1 Turn off the computer; open the battery cover; and install the

new or discharged battery pack into the computer.

2 Close the battery cover.
3 Connect the AC Adapter to the computer.

The system status indicators show the following:

Chapter 4. Using Battery Power 4-3

Charging the Battery Pack

Battery Pack Maintenance

Many users are familiar with the phenomenon known as battery
memory, where after repeated partial charging and discharging the

battery pack appears to lose some of all of its original capacity. The
nickel/metal-hydride (NiMH) battery packs used by the ThinkPad are
less susceptible to memory development than are the more
common nickel/cadmium (NiCd) batteries. However, to ensure the
longest possible battery life, in terms of both length of use per
charge and number of charge and number of charge and discharge
cycles before wearing out, please observe the following guidelines:

• Battery packs shipped from the factory are in an almost
discharged state, so you must charge them fully before use.

• When charging, always charge the battery pack fully. Even if
you only need to run on battery power for a fraction of the
battery’s capacity, you should not try to give the battery a partial
charge.

• Normal charging causes the battery pack to heat up slightly. Let
it cool for 15 minutes before you use it.

• Immediately after the battery pack has been drained of power, it

4-4 IBM ThinkPad 310E/310ED: User’s Guide

may be warm to the touch. This is normal. However, for longer
battery life, it should be set aside to cool for 15 minutes before
recharging.

Replacing the Battery Pack

When the AC Adapter is connected, you can replace the battery
pack whenever it is low in power. Without the AC Adapter, the
battery pack can be replaced when the computer power is off, or
when the computer is in hibernation mode. To replace the battery
pack during hibernation mode and without turning off the computer,
follow these instructions.

Important!

• If you are using PC Cards, either connect the AC Adapter or

Preserving Battery-Pack Life

To preserve the life of the battery pack:

Maximizing Battery-Powered Operation

Attention:

Make sure the battery pack power is
completely used before you recharge
it. Recharging a battery pack that is
not completely discharged can
shorten battery life.

• Do not charge the battery pack until all of its power is used.

• Once you have started charging the battery pack, do not use

it until it is fully charged.

• Discharge the battery pack occasionally.

• Turn off the computer whenever it is not in use.

Maximizing Battery-Powered Operation

To save battery power:

• Use Advanced Power Management (APM)

• Decrease the LCD brightness

• Use the Battery Power-Management function

Using Advanced Power Management

Note:

If you have purchase this computer
with a preinstalled operating system,
APM is already installed correctly.

The computer has power-management functions built in. No special
power-management drivers have to be installed before you use the
computer. However, the computer is able to conserve more power
when Advanced Power Management (APM) is used.

APM allows you to reduce power consumption when your
applications and devices are idle. Each operating system comes
with its own APM.

Chapter 4. Using Battery Power 4-9

Note:

Sleep Manager needs to be installed
to use Hibernation. If Sleep Manager
is not yet installed on your computer,
see page 7-8 and 7-19 for
instructions on how to install Sleep
Manager.

Your computer has built-in battery power-saving functions to save
power when you use the battery pack or AC Adapter.

When resuming normal operation from one of the modes, use the
resume function to return to where you were when you entered that
mode. Because the operating system is already loaded, the resume
function is faster than turning on the power.

The following are the two power-saving modes:

• Standby mode (Fn+F7). You can enter standby mode for short
idle times, such as when you are taking a short break from work.

• Hibernation mode (Fn+F8). You can enter hibernation mode
when you leave your office for the day.

It takes more time to return to normal operation from hibernation
mode than to return from standby mode, but the computer does not
use power.

4-12 IBM ThinkPad 310E/310ED: User’s Guide

Using Power Management

The following figure shows the operations required when the
computer moves from a power-off condition to operation mode, and
vice versa.

Chapter 4. Using Battery Power 4-13

Using Power Management

Display Standby Mode In display standby mode, the computer shuts off the LCD backlight

and turns off the CRT video as well, if there is no activity from the
keyboard, TrackPoint III or external mouse within the period
specified by the Display Standby Timer. To turn the display back
on, press a key, move the TrackPoint or external mouse.

Hard Disk Standby Mode In this mode, the hard disk drive spins down and enters a standby

state if there are no disk read/write operations within the period
specified by the Hard Disk Standby Timer. The hard disk drive
automatically powers back on when accessed.

Standby Mode In standby mode, the hard disk drive stops and the LCD turns off.

The computer immediately resumes normal operation when you
press any key or use any pointing device. Also, if a power-saving
monitor (Energy Star monitor) is in use when the computer enters
standby mode, the computer activates the monitor’s low-power
mode.

Points to Consider When Using Standby Mode

Consider the following before using standby mode:

• The computer enters standby mode if the LCD is closed.

• Pressing the power switch when the computer is in standby

• When entering standby mode or resuming normal operation with

• When a PC Card is installed, the computer may not enter

standby mode.

Hibernation Mode

Using Power Management

Notes:

1. Before using hibernation, Sleep
Manager (the hibernation utility)
must be installed and run.

2. Using a particular PC card can
disable hibernation mode.

3. With a base memory of 16MB, it
takes approximately 20 seconds
to enter hibernation mode and
36 seconds to resume normal
operation. (The time to enter or
exit hibernation mode depends
on the computer memory size.)

Attention:

The hibernation file must not be
created in a compressed data area of
the hard disk.

In hibernation mode, all tasks are stopped and memory data and the
current status of the computer are stored on the hard disk drive;
then power is turned off. No battery power is used. When power is
turned on again, the computer automatically restores the tasks and
resumes normal operation. When the computer enters hibernation
mode, you hear one short beep. A graphical message appears;
then a short beep sounds again to inform you that the computer has
entered hibernation mode.

Creating the Hibernation File

When installing an operating system or installing additional
computer memory, you must create a hibernation file on the hard
disk drive to use the hibernation mode. (You only need to create
the hibernation file once after installing an operating system or
additional memory.)

The Sleep Manager program, once installed, automatically creates
and manages the hibernation file for you.

The size of the hibernation file will be greater than total memory.
For example, if base memory is 16MB and you have installed an
optional 16MB memory module (DIMM), the hibernation file is
33MB:

(16MB + 16MB) + 1MB = 33MB
The following describes how to create a hibernation file for your

operating system.

Chapter 4. Using Battery Power 4-15

Using Power Management

Note:

To verify if the hibernation file is
valid, you can rest your cursor on the
Sleep Manager icon on the taskbar.

If the file is valid, the icon displays
Save-to-disk feature valid. If the
file is invalid, you need to create the
hibernation file again.

If you using Windows 95

1 Turn on the computer.
2 Click on the Start button.
3 Select the Programs folder.
4 Select Sleep Manager icon.
5 Click on the Create button.

The computer can now enter hibernation mode.

reinstall the PC Card before
restarting the system or application
program.

1 Turn on the computer.
2 Type SLEEPMGR /C at the command prompt; then press

Enter.

The hibernation file is created on drive C.

Points to Consider When Using Hibernation Mode

Consider the following before using hibernation mode:

• Do not turn off the computer while the hibernation file is being
created.

• Create the hibernation file only on the hard disk drive installed in
the computer. The hibernation file is read-only.

• The computer reserves some battery power when it is set to
enter hibernation mode when a low-battery condition occurs.
This can cause the battery operating time to be reduced.

• When entering hibernation mode or resuming normal operation
with a PC Card, if the application or the computer does not
operate, restart the application or the computer.

• When a PC Card is installed, the computer may not enter
hibernation mode.

Installing PC Cards

Installing PC Cards

Your computer has two slots that allow you to plug in credit-card-size
PCMCIA cards (called PC cards) that support the PCMCIA Standard
release 2.01 or later..

There are different types of PC Cards. Your ThinkPad 310E/310ED
supports Type I, Type II, and Type III cards. The PCMCIA slots can
be used for the following combinations:

• One or two Type I

• One or two Type II

• One Type I and one Type II

• One Type III

Before Installing PC Cards

Be sure to read “Using PC Cards” on page 3-18.

For information about the type of PC Cards to install, see Appendix
B, “Advanced Information for PC Cards”.

To install a PC Card in your computer, follow these steps:

1 Insert the PC Card into one of the available slots. There is a

gentle click when the PC Card has been fully inserted.

Installing PC Cards

Insert the PC Card with the long row of pin sockets facing the

computer and the label on the PC Card facing up. If the PC

Card will not fit into the slot, turn the card over. The PC Card

can fit into the slot only when inserted the correct way. Do not

try to force the card into the slot.

You can insert a Type I or Type II PC Card into either available

slot. A Type III PC Card occupies both slots. However, when

you insert a Type III card, aim its bottom ridges at the lower PC

Card slot.

2 You can now attach the appropriate devices and cables to your

installed PC Card.
To insert an additional Type I or Type II card when one is already

installed, follow the same direction, placing the new card into the
available slot.

Once you have installed the PC Card, Windows 95 recognizes that a
card has been installed and beeps or displays the PC Card window
on your screen. From the PC Card icon in the Control Panel, you
can configure your PC Card by choosing various settings to be used
each time you insert any PC Card or use this particular PC Card.
For more information about configuring your PC Card, see “Using
PC Cards” on page 3-18.
