DANGER

Do not disassemble, incinerate, or short-circuit the rechargeable battery pack. Do not put it in trash that is disposed of in landfills. Dispose of it as required by local ordinances or regulations. In the United States, call IBM at 1-800-IBM-4333 for information on disposal.

DANGER

The lithium battery (IBM P/N 12J0453 UL-recognized component—File No. MH12210) can be replaced only by your dealer or an IBM service representative. It contains lithium and can explode if not properly used, handled, or disposed of. Do not: (1) throw or immerse into water, (2) heat to more than 100°C (212°F), or (3) repair or disassemble. Dispose of it as required by local ordinances or regulations.

CAUTION: The fluorescent lamp in the liquid crystal display (LCD) contains mercury. Do not put it in trash that is disposed of in landfills. Dispose of it as required by local ordinances or regulations.

The LCD is made of glass, and rough handling or dropping the computer can cause the LCD to break. If the LCD breaks and the internal fluid gets into your eyes or on your hands, immediately wash the affected areas with water for at least 15 minutes; then get medical care if any symptoms are present after washing.

Laser Compliance Statement

The CD-ROM or DVD-ROM drive in the IBM ThinkPad 770X computer is a laser product. The drive's classification label (shown below) is located on the top of the drive.

CLASS 1 LASER PRODUCT LASER KLASSE 1 LUOKAN 1 LASERLAITE APPAREIL A LASER DE CLASSE 1 KLASS 1 LASER APPARAT

The drive is certified in the U.S. to conform to the requirements of the Department of Health and Human Services 21 Code of Federal Regulations (DHHS 21 CFR) Subchapter J for Class I laser products.

In other countries, the drive is certified to conform to the requirements of EN60825.

DANGER

Do not open the CD-ROM or DVD-ROM drive; no user adjustments or serviceable parts are inside.

Use of controls, adjustments, or the performance of procedures other than those specified might result in hazardous radiation exposure.

Class 1 laser products are not considered to be hazardous. The CD-ROM or DVD-ROM drive has an internal, Class 1, 0.5-milliwatt, aluminum gallium-arsenide laser that operates at a wavelength of 760 to 810 nanometers. The design of the laser system and the CD-ROM or DVD-ROM drive ensures that there is no exposure to laser radiation above a Class 1 level during normal operation, user maintenance, or servicing conditions.

xiv IBM ThinkPad 770X User's Reference

This chapter provides basic information about your computer.

To power off the computer, hold the power switch for just a second and release it. Wait at least 5 seconds before powering on again (or resuming normal operation from suspend or hibernation mode).

The TrackPoint consists of a stick on the keyboard and three click buttons below the keyboard. Movement of the cursor on the screen

is controlled by the amount of pressure that you apply to the nonslip cap on the stick in any direction parallel to the keyboard; the stick itself does corresponds to the pressure you apply to the stick. The functions of the left and right click buttons correspond to those of the left and right mouse buttons on a traditional mouse; these functions depend on the software you are using.

If you are not familiar with using the TrackPoint, these instructions will help you get started:

Place your hands in the typing position and press gently with either index finger on the stick in the direction 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. You can also move the cursor side to side by pressing sideways.

The cursor might drift. This is not a defect. Do not use the TrackPoint until the cursor stops moving.

Screen expansion

Key Combination Meaning

The LCD screen image size switches between expanded and normal mode if the size of your LCD image is smaller than that of the physical LCD.

If your computer is equipped with a 13.7-inch SXGA display used in standard VGA mode, such as MS-DOS full screen mode or the safe mode screen of Windows 98 or Windows 95, computer output is displayed in expansion mode. In this case, you cannot switch the LCD screen image size.

If the computer is in suspend mode and you press the Fn key independently without any function key, the computer returns to normal operation.
