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.
OmniBook 3000:
Battery status. Shows the approximate charge level of the battery relative to a full
charge. Each bar represents approximately 10% charge.
The upper and lower triangles indicate the presence of the main battery (upper) and a
second battery (lower). A triangle blinks when that battery is charging. The main
battery charges first, discharges last.
OmniBook 2100/3100: If two batteries are installed, the indicator shows the combined
charge of both batteries.
OmniBook 3000: 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, the indicator shows the combined charge of both batteries.
Press Fn+F6 to show separate battery levels.
Battery low. (Triangle, but no bars.) The OmniBook also beeps.
Defective battery. (No triangle, no bars.) No charging, even though ac adapter is
present.
OmniBook 3000:
Overheated battery. (No triangle, top bar.) The battery is too hot to charge. Not
necessarily a defective battery.
Internal drive. The OmniBook is accessing one of the internal drives: the hard disk
drive, CD-ROM drive, or other plug-in module drive.
Floppy disk drive. The OmniBook is accessing the floppy disk drive.
Blinks
when the battery is being charged.
PC Card. There is activity between the PC Card and the computer.
Caps Lock. Caps Lock is active.
Num Lock. Num Lock is active.
Keypad Lock. The embedded keypad is active (Fn+F8). Num Lock must also be on
for the numeric keys—otherwise, cursor control is active.
Scroll Lock. Scroll Lock is active.
OmniBook 3000:
(scrolling)
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.
HP OmniBook 2100/3000/3100 Product Information 1-5
The green power light in the hinge area (located on the icon PCA) indicates the power state. The
green lights on the main battery or secondary battery indicate its charge level.

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 1-15—it lists the roles that 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.

* Recommended replacement parts. HP recommends stocking drives from IBM, the primary hard drive
source for these OmniBook products. IBM drives can be used with the older HDD case that has no top
shield (the shield should be installed if it is present). Toshiba hard drives require a top shield as part of the
HDD case.
Required Equipment
• Small Phillips screwdriver.
Removal Procedure
1. Unplug the ac adapter, if present, and remove the battery.
2. Remove the two screws from the bottom of the hard drive.

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.
HP OmniBook 2100/3000/3100 Removal and Replacement 2-5
4. If you are installing a new hard drive that does not have a plastic case, you can remove the case
from the old hard drive:
• Remove the four screws from the sides of the case.
• Remove the top shield from the drive and swing out the free end of the hard drive about 90°,
then gently pry off the connector from the hard drive. The OmniBook 3000 may not have a
top shield.
Caution:
For a Toshiba drive, make sure
the HDD case has a metal top
shield.
Caution:
The top shield for a 9.5-mm drive
has spacers.
HDD Case (Kit)
(includes M3×5mm screws)
Figure 2-4. Installing a Hard Drive in the Case
Reassembly Notes
Caution
• Use a HDD case kit that is compatible with the thickness of the drive, 9.5 mm or 12.7 mm.
The 9.5-mm drive requires spacers inside the top shield.
• Install the metal top shield that is included with the HDD case. If an older HDD case does not
have a top shield, you must install a newer HDD case if the drive is a Toshiba drive—
otherwise, drive performance may be reduced by magnetic interference.
• Do not cover the vent hole in the top surface of the hard drive or in the case. If you cover the
hole, the hard drive could fail prematurely.
• Depending on the manufacturer of the replacement drive, the hole placement for the four screws
may vary.
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 Recovery CD and internal CD-ROM module for the computer
model you are repairing, create a Support Utility floppy disk 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.
2-6 Removal and Replacement HP OmniBook 2100/3000/3100
¨
On any computer that has a CD-ROM drive, run makesupp from the
\Omnibook\Drivers\Hputils directory on the OmniBook Recovery CD.
¨
On any computer with World Wide Web access, download the Support Utility software
package from the OmniBook website (see page vi). Follow the instructions provided.
2. Insert the Recovery CD in the CD-ROM drive—or insert the Support Utility disk in the floppy
drive.
3. Reboot the computer. If you are using the Recovery CD, press ESC during reboot if the
OmniBook screen appears, ESC to display the boot-device menu, then select the CD-ROM drive
as the boot device.
4. When prompted, select “Create Hibernate Partition.”
OmniBook 2100/3100: We recommend that you create a partition the same as the factory setup—
288 MB for a Pentium II CPU, or 192 MB for a Pentium CPU (160 MB is acceptable if the
motherboard has only one RAM slot).
OmniBook 3000: We recommend that you create a 144-MB partition, the same as the factory
setup.
