2.4 Identifying the Computer Features

This section identifies and describes each computer feature.

PICTURE 39

# 1 Display (LCD, liquid crystal display) displays output. You can also | use an external PS/2 (*) display by connecting it to the external PS/2 display connector at the rear of the computer.

2 Release Buttons are located on both sides of the computer. Pushing these buttons causes the upper part of the computer to pop-up slightly so that you can easily open the computer.

3 Contrast Control adjusts the contrast of the display.

4 Brightness Control adjusts the brightness of the display.

5 Power Switch turns the computer on (I) and off (O).

6 Diskette-Eject Button releases a diskette from the drive. 1.44 is printed on the button to indicate that it is a 1.44MB diskette drive (see page A.1 for more information).

7 Diskette Drive reads data from or writes data to a diskette. For information about using the correct diskettes, see page A.1.

@ Because the diskette drive can be affected by a magnetic field, you @ should not use the system unit near electric appliances such as a TV @ set or a speaker. If you use a PS/2 or other display near the system @ unit, set it more than 13 cm (5 in.) away from the diskette drive.

8 System Status Display shows the computer status by using small symbols called icons (see page 2.5 for the meaning of each symbol).

9 Numeric Keypad is an auxiliary input device consisting of 17 data keys and is connected to the pointing-device connector at the rear of the computer. The numeric keypad has a connector to accept a mouse.

| 10 IBM Mouse is an optional pointing device that can be connected either to the numeric keypad or to the pointing-device connector at the rear of the computer.

11 Keyboard is used to enter information into the computer.

12 Economy Switch determines the processing speed of the computer to economize on power usage. There are two modes.

If A (automatic) mode is selected, the computer varies its processing speed depending on how much activity occurs. This mode conserves battery power. If the M (manual) mode is selected, you can run the # computer at a fixed processing speed specified on the Set Features # Menu (see page 3.8.3).

1 Power Jack is where the AC Adapter plugs in.

2 Pointing Device Connector is where a mouse or keypad cable plugs in. When you connect the numeric keypad into this connector, a mouse can be plugged into the connector on the rear of the numeric keypad.

| 3 Parallel Connector is where a printer or adapter signal cable plugs | in. These devices should be compatible with the Centronics (**) | parallel interface.

| 4 Serial Connector is where a 9-pin serial device cable plugs in. It is fully programmable and supports asynchronous communications.

# 5 Rechargeable Battery supplies the power required to operate the # computer. The Rechargeable Battery can be removed.

Note: This computer has two additional batteries installed inside the computer: the Backup Battery and the Standby Battery. For more information, see page 3.1.1.

# 6 External PS/2 Display Connector is the place where the signal cable # of a display that supports a video graphics array (VGA) resolution # can be plugged in. Be aware that some display plugs may not fit this # connector.
