Using Fn Hot Keys

The Fn key combined with another key is a hot key—a shortcut key sequence for various system controls. For an external keyboard, CTRL+ALT is normally equivalent to the Fn key.

Table 1-4. Fn Hot Keys

Hot Key Effect

Fn + F1 Decreases the display’s contrast (DSTN displays only). Fn + F2 Increases the display’s contrast (DSTN displays only). Fn + F3 Enters Suspend mode (Windows 98); enters Standby mode (Windows 95, Windows NT). Fn + F4 Enters Suspend mode. Fn + F5 Enters Hibernate mode. Fn + F6 Toggles the sound on and off (mutes sound). Fn + F12 Switches among the built-in display, an external display, and simultaneous displays. Fn + NumLock Toggles Scroll Lock on and off. Fn + UP ARROW

Fn + DOWN ARROW

Increases and decreases the sound volume.

Resetting the OmniBook

1. Use a pen or a straightened paper clip to push the system-off button on the bottom of the

OmniBook. (The switch is on the motherboard.)

–or– Press and hold the blue power button until the display shuts down. (The switch is on the I/O

PCA.)

2. After the computer shuts down, press the blue power button to turn it back on.

Note

The OmniBook can boot from a CD if both of these conditions are true:

• You have a bootable CD in the drive, such as the OmniBook Recovery CD, and

• You select the CD-ROM drive as the boot device. You can do this during reboot by pressing ESC to cancel the OmniBook screen, then ESC to display the boot-device menu for a onetime selection.

Internal Design

The motherboard PCA is the central component of the OmniBook design. It plays a role in virtually all system functions. The CPU module and most other subsystems connect to the motherboard.

The following figure shows the connections among the replaceable electrical modules. As a substitute for a functional block diagram, see the table on page 1-13—it lists the roles that the replaceable

modules play in each of the functional subsystems.

Removing the Battery

(User-Replaceable)

Carefully read the following information.

Caution

• Do not mutilate, puncture, or dispose of batteries in fire or water. A battery can burst or explode, releasing hazardous chemicals. A rechargeable battery must be recycled or disposed of properly.

• When discarding a battery, contact the local waste disposal provider regarding local restrictions on the disposal or recycling of batteries.

• To avoid risk of fire, burns, or damage to the battery, do not allow a metal object to touch the battery contacts.

• The battery is suitable for use only with compatible OmniBook models.

• Do not disassemble. There are no serviceable parts inside.

• Handle a damaged or leaking battery with extreme care. If you come in contact with the electrolyte, wash the exposed area with soap and water. If it contacts the eye, flush the eye with water for 15 minutes and seek medical attention.

• Do not expose the batteries to high storage temperatures (above 60 °C, 140 °F).

Required Equipment

• None.

Removal Procedure

1. Unplug the AC adapter, if present.

2. Turn the notebook bottom side up.

3. Push the blue latch in the direction of the arrow (to your left) and lift out the battery.

Figure 2-1. Removing the Battery

Reassembly Notes
