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.

Indicator

(scrolling)

Table 1-4. Status Panel Indicators (Icon PCA)

Meaning

AC power. The ac adapter is plugged in.

OmniBook 3000: 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 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.

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:

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.

*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.

3.Pull out the hard drive.

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.
