Turning the OmniBook On and Off
• On. Press the blue power button to turn the computer on.
• Standby. Occurs automatically if the computer is inactive for about 2 minutes.
• Suspend. Press the blue power button briefly (about 1 second) to suspend activity when the
OmniBook is on. The computer resumes your previous work session when you turn it back on.
Closing the lid (for more than 2 seconds) also suspends the computer. (If an external monitor is
connected, closing the lid merely turns off the built-in display and turns on the external display.)
• Hibernate. Press Fn+F12. The computer completely shuts down, but your current work session is
first saved to disk. The computer will reboot and restore your previous session when you turn it
back on.
• Off. Press the blue power button for more than 4 seconds to completely shut down the computer.
Unsaved data is lost. The computer will reboot when you turn it back on.

Reduced-power/stopped state. Everything is in a reduced-power state. Network devices are
maintained. Your current work session continues at turn-on (any key-press).
Low-power/stopped state. Lower power state than Standby. Everything is off or in a lowpower state. Network devices are off. Your previous work session resumes at turn-on. For
plug-and-play operating systems, network connections resume at turn-on.
No-power/stopped state. Session is saved on the hard disk. Everything is shut down.
Computer reboots at turn-on and restores previous session and network connections (if
plug-and-play).
No-power/stopped state. Everything is shut down (battery continues charging if ac adapter
is connected). Computer reboots at turn-on and restores network connections (if plug-andplay).
HP OmniBook 3000 Product Information 1-3
Checking the Status of the OmniBook
The OmniBook status panel, located above the keyboard (on the icon PCA), contains indicators that
show the current status of the OmniBook. The indicators in the status panel show keyboard status, drive
status, and power status.
Table 1-4. Status Panel Indicators (Icon PCA)
Indicator Meaning
AC power. The ac adapter is plugged in.
Blinks when the battery is being charged.
Battery status. Shows the approximate charge level of the battery relative to a full
charge. Each bar represents a 10% charge.
The upper and lower triangles indicate the presence of main (upper) and secondary
(lower) batteries. A triangle blinks when that battery is in use. The main battery
charges first, discharges last.
If two batteries are installed and the ac adapter is connected, the indicator shows the
level of the battery being charged. If the ac adapter is not connected, indicator shows
the combined charge of both batteries. Press Fn+F6 to show separate battery levels.
Battery low. The outline blinks when the battery charge is critically low. The
OmniBook also beeps.
Defective battery. No battery activity; no charging.
Overheated battery. The battery is too hot to charge.
CD-ROM drive or hard disk drive. The OmniBook is accessing one of these built-in
(scrolling)
drives.
Floppy disk drive. The OmniBook is accessing the floppy disk drive.
PC Card. There is activity between the PC Card and the computer.
Suspend mode. These symbols flash from left to right when the OmniBook is
suspended (turned off by pressing the power button briefly).
If ac power is not connected, the green power light also blinks slowly.
Caps Lock. Caps Lock is active.
Num Lock. Num Lock is active (Fn+F9).
Keypad Lock. The built-in embedded keypad is active (Fn+F8). Num Lock must also
be on for the numeric keys.
Scroll Lock. Scroll Lock is active (Fn+F10).
The green power light (located on the icon PCA) indicates the power state. The green lights on the main
battery or secondary battery indicate its charge level.

Using Functions Keys (F1 through F12)
The top row of the keyboard has twelve function keys that serve as hot keys—shortcut key sequences—
for various system controls.
Table 1-6. Function Keys (F1-F12)

Fn + F2 Increases the display’s brightness.
Fn + F3 Decreases the display’s contrast (non-TFT displays only, if available).
Fn + F4 Increases the display’s contrast (non-TFT displays only, if available).
Fn + F5 Switches among the built-in display, an external display, and simultaneous displays.
Fn + F6 (hold) For use with two batteries: The battery indicator in the status panel briefly displays the
individual battery status for each battery, then resumes displaying the combined
battery status.
Fn + F7 Toggles the sound on and off (mutes sound).
Fn + F8 Toggles the built-in keypad on and off. Does not affect an external keyboard. If Num
Lock is on, then the numeric functions are active; otherwise, cursor control is active.
Fn + F9 Toggles Num Lock (numeric functions for the keypad) on and off.
Fn + F10 Toggles Scroll Lock on and off.
Fn + F12 Enters Hibernate mode.

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 (MMO) and all 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 1-10—it lists the roles the replaceable modules
play in each of the functional subsystems.

Caution
Always provide proper grounding when performing repairs. Without proper grounding, an
electrostatic discharge may damage the OmniBook and its components.
Notes
Reassembly steps are the reverse of the removal steps. Reassembly notes are included at the
end of each section below.
Symbols like this throughout this chapter show approximate full-size screw outlines. You
can use them to verify the sizes of screws before you install them. Installing a wrong-size screw
can damage the unit. (The symbol at the left represents an M2.5×5mm screw.)

Removing the Main Battery
(User-Replaceable)
The main battery is located under the right corner of the palmrest. To remove a secondary battery (an
accessory plug-in module), see the next topic below.
WARNING
Do not mutilate, puncture, or dispose of batteries in fire. A battery can burst or explode,
releasing hazardous chemicals. A rechargeable battery must be recycled or disposed of
properly.
Required Equipment
• None.
Removal Procedure
1. Slide the safety latch for the battery compartment into its recess.
2. Slide and hold the release latch, then slide out the battery.

accessories are available, including a CD-ROM drive and secondary battery.
Note
Plug-in accessory modules have no repairable components. A defective module must be
exchanged.
Required Equipment
• None.
Removal Procedure
1. Slide the safety latch for the plug-in slot into its recess.
2. Slide and hold the release latch, then slide out the module.

Caution
Work the connector off the hard drive evenly, without pulling on the flex cable. Otherwise, you
may bend connector pins on the hard drive or damage the flex cable.
4. If you are installing a new hard drive that does not have a plastic carrier, you can remove the carrier
from the old hard drive:
• Remove the four screws from the sides of the carrier.
• Swing out the free end of the hard drive about 90°, then gently pry off the connector from the
hard drive.

Reassembly Notes
• Depending on the manufacturer of the replacement drive, the hole placement for the four screws
may vary. However, only the indicated IBM drives are qualified at this time.
Important
If you are installing a new hard drive, you should create a Hibernate partition on the drive before
loading any software—see the steps below.
Creating a Hibernate Partition
1. If you do not have an OmniBook 3000 Support Utility floppy disk, create one now. After inserting a
formatted floppy disk: in the floppy drive, do one of the following:
On a factory software installation, click Start, Programs, OmniBook, Create Support Utility
Disk.
On any computer, run makesupp from the \Omnibook\Drivers\Hputils directory on the
OmniBook 3000 Recovery CD.
On any computer, download the Support Utility software package from the OmniBook website
(see page vi). Follow the instructions provided.
2. Insert the Support Utility disk in the OmniBook floppy drive.
3. Reboot the computer.
4. When prompted, select “Create Hibernate Partition.”
We recommend that you create a 144-MB partition, the same as the factory setup.
