Providing Power

Your computer can be used both inside and outside your office area. Different power sources for the computer are available for different conditions: the AC Adapter, battery pack, or Car Battery Adapter. When you are using the computer as a desktop computer, you can use the AC Adapter which provides continuous power. When traveling outside your office area, you can use the charged battery pack. A Car Battery Adapter is available (an option) for you to charge the battery pack in your car when it is low in power.

AC Adapter

Warning:

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.

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 or 100–125 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.

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

If you turn on the computer when the battery pack is installed, you will hear a short beep when you connect or disconnect the AC adapter from the computer. This short beep means that the power source has been changed.

When you disconnect the AC Adapter from the computer with a battery pack installed, the LCD brightness becomes slightly dimmer to conserve battery power.

Chapter 2. Getting Familiar with Your Computer 21

Providing Power

Battery Pack

The battery pack is an internal power source for the computer when the AC Adapter is not available. The battery pack is rechargeable with the AC Adapter or the Quick Charger (an option).

The following table shows the operating time, in hours, of the computer with a fully-charged battery pack.

The operating time depends on the applications and the configuration of the system. The actual battery operating hours might be shorter or longer than the time indicated, especially when using the CD-ROM drive.

Operating with the TrackPoint III

Notes:

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

2. Drifting is a characteristic of the TrackPoint III and is not a defect. Do not use the TrackPoint III until the pointer stops moving.

The keyboard contains a unique cursor-pointing device called the 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 adds a stick 1 to the keyboard and a pair of click buttons 2 below the keyboard. The motion of the cursor is controlled by pressure applied to the stick in any horizontal direction; the stick does

not

move. The speed at which the cursor moves corresponds to the amount of pressure on the stick. The function of the click buttons is similar to those on other pointing devices; what they do depends on the software that is used.

Trademark of the IBM Corporation.

24 IBM ThinkPad 755CD User's Guide

Operating with 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:

Either thumb can be used.

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.

Use the click buttons to select and drag as required by your software, in the same way as for any other pointing device.

You can easily drag an item across the screen without having to continually press the click buttons of the TrackPoint III. To drag-and-drop an item, press; then slide the click button toward the front of the computer. The click button locks into place so you can drag an item across the screen using the TrackPoint III without holding down the click button.

To release the latch, press the side of the click button.

Operating with the TrackPoint III

Cleaning the Cap

The cap 1 on the end of the TrackPoint III is removable. You can replace it with one of the spares shipped with your computer when the cap is worn out.

To maintain a smooth pointing operation, occasionally clean the cap with a soft cloth moistened with non-alkaline detergent.

page 202.

Operational modes:

page 38.

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

Operational Modes

The operational modes set the computer to control the processor speed or to set timers for saving power.

Power-Saving Modes

The power-saving modes set the computer to stop all tasks when the computer is not used for a specified time to save power.

When resuming normal operation from one of the modes, the resume function sets the computer to return to where it was when it entered that mode. Because the operating system is already loaded, the resume function is faster than power-on.

For more information about the operational modes, see page 38.

The following are the three power-saving modes:

Standby Mode Enter standby mode for short idle times. Suspend Mode Enter suspend mode for short times away from

your desk.

Hibernation Mode Enter hibernation mode when you leave your

office for the day.

It takes more time to return to normal operation from hibernation mode than from suspend or standby mode, but the computer does not use any power during hibernation mode. On the other hand, it takes only a short time to return from standby mode, but the amount of power saved in standby mode is less than in suspend or hibernation mode.

A comparison of the power conserved and the time required to return to operational mode is shown in the following figure.

Considerations for Hibernation Mode

Consider the following before using hibernation mode.

Do not run any tasks 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 hidden and cannot be accessed.

The computer uses battery power to enter hibernation mode. Therefore, it reserves some battery power when it is set to enter hibernation mode at a low-battery condition. This can cause the battery operating time to be shorter than the time shown on page 22.

When you enter hibernation mode while playing musical compact discs or multisession Photo CDs, you will not return to where you left off after resuming normal operation.

When the computer is powered with ac power and is using one of the following IBM PC Cards, it does not enter hibernation mode.

– IBM PCMCIA Data/FAX Modem – IBM High Speed PCMCIA Data/FAX Modem – IBM 3270 Emulation Credit Card Adapter – IBM Token-Ring 16/4 Credit Card Adapter – IBM Credit Card Adapter for Ethernet – IBM 5250 Emulation Credit Card Adapter

This prevents possible problems from occurring with communication application programs after the computer returns to normal operation.

Note:

If the communication is still not reestablish, remove; then reinstall the PC Card before restarting the system or application program.

‡

When the computer returns to normal operation, remove the PC Card from the computer and reinstall it. Communication returns automatically.

When the computer is powered with battery power, the computer turns power off to the PC Card. When resuming normal operation, if the PC Card or computer does not operate, restart the application or computer.

Using the Infrared Communication

Communicating with IR

Note:

When installing an operating system, you must install the infrared device driver to use the ThinkPad mode.

To install IR device driver:

Page 215.

Your computer is equipped with an infrared (IR) communication feature that allows point-to-point communication with other ThinkPad computers or systems equipped with an infrared port. There are two IR ports, one in the front of the computer below the CD-ROM drive and the other on the rear of the computer.

The IR feature supports three different modes with the following communication speed in bits per second (bps):

ThinkPad (1.15 Mbps)

This mode is used when communicating with another 755 series computer with an infrared port or other systems supporting ThinkPad mode.

Generic (up to 115 Kbps)

This mode is used when communicating with other IBM ThinkPad computers, a Hewlett Packard** 100LX**, Omnibook**, or other systems with infrared ports supporting Generic mode.

Sharp (9600 bps)

This mode is used when communicating with the Sharp

Wizard** or other systems with infrared ports supporting Sharp mode.

The ThinkPad Features program contains a utility program that enables the front or rear IR port and the communication speed.

If you are using OS/2 or Windows: If you are using DOS:

Type PS2 ? at the command prompt;

Communicating with IR

When communicating with rear IR ports

directly with each other at a communicating distance.

It is recommended that the communicating ThinkPad computers use their rear infrared port to communicate with each other.

, the IR ports must face

When communicating between a front IR port and an IR port on another computer

with each other at a communicating distance.

, the IR ports on the computers must face directly

76 IBM ThinkPad 755CD User's Guide

Communication can be affected by the light from the LCD of the computer. To avoid this, open the LCD of the computer to a wide angle.

[Viewed from the sides of the computers.]

Considerations for Communication

Consider the following when communicating with the IR ports.

Communicating with IR

ThinkPad Features program:

Page 36.

You need to run the same communication application to communicate between your computer and the other computer or device. Refer to the application manuals for more information.

Run only one application at a time to communicate with the IR ports.

When using applications that use a conventional serial port and serial cable to exchange data, your computer IR ports are used as a replacement for the serial port and cable. In this case, the ThinkPad mode cannot be used.

The communicating distance might be shorter if:

– The other system is not the same model as your computer. – There is interference from the ambient light. It is

recommended not to use IR communication during bright sunshine or artificial light conditions.

– The IR port is not directly facing the other communicating

port.

Using Mwave DSP Audio Features

OS/2

Note:

When you use the WIN-OS/2 environment, see“Using for Windows or WIN-OS/2” on page 83 .

Using the Function for OS/2

Mwave supports the audio function in the OS/2 environment through Multimedia Presentation Manager/2* (MMPM/2*). To use the Mwave audio functions with OS/2, refer to the MMPM/2 manuals.

For Your Information

When you play the wave audio files, select the DIGITAL

AUDIO icon.

When you play the MIDI sequencer files, select the MIDI

icon.

Considerations for WIN-OS/2 Environment

The following are considerations when playing MIDI files in the WIN-OS/2 environment.

To play MIDI files in the WIN-OS/2 environment from the OS/2 desktop, the Audio Mode in the Mwave Audio Options menu must be set to Normal (not Audio/Image Synch).

The MWS.EXE program must be running in the same session as the program that runs the MIDI file. If you use multiple WIN-OS/2 sessions, MWS.EXE must be started in each session. To run MWS.EXE, migrate it to the OS/2 desktop and start it before starting the MIDI application programs. To migrate MWS.EXE to the OS/2 desktop, refer to the OS/2 manuals.
