Operating the OmniBook XE2

Configuring the OmniBook with the BIOS Setup Utility

The BIOS (Basic Input and Output System) Setup utility is a menu-driven utility that lets you change the system configuration and tailor the operation of your OmniBook to your individual work needs.

Some settings made in the BIOS Setup utility control the hardware and consequently have a fundamental effect on how the OmniBook operates.

This section describes the BIOS Setup utility menus and options in detail.

To run the BIOS Setup utility

1. Close all applications, then shut down Windows and restart the OmniBook.

2. When you see the HP logo, press F2 to enter the BIOS Setup utility.

3. The pointing devices are not active in the BIOS Setup utility. Press the RIGHT and LEFT arrow keys to change menus. Press the DOWN and UP arrow keys to move among parameters in a menu. Press F5 or F6 to change values for the current parameter or press ENTER to change a setting. See the tables below for more information.

4. After you select the options you want, press F10 or use the Exit menu to exit the BIOS Setup utility.

If the settings cause a conflict between devices during reboot, the system

prompts you to run BIOS Setup, and the conflicting settings are marked.

Caution

To update the OmniBook BIOS

Hewlett-Packard may update the BIOS to enhance the capabilities of the OmniBook. Updates will be available from HP Electronic Support Services at either http://www.hp.com/cposupport/eschome.html or http://www.hp.com/cposupport/mobile_computing/software/xe2_100.exe.html.

Because a BIOS update replaces the previous version, it is very important you follow these instructions exactly. Otherwise, the OmniBook may be damaged.

The BIOS update process resets the configuration settings in the BIOS Setup utility except for the password, date and time.

1. From the Start menu, shut down the OmniBook.

2. Undock and connect the ac adapter to the OmniBook.

3. Remove any PC Cards.

4. Insert the BIOS Update disk in the floppy disk drive.

5. Press the blue power button.

6. When prompted, choose the correct language.

7. When prompted, press C. This starts a process that takes approximately 1

minute. Once it begins, do not interrupt the update process.

8. When prompted, insert a paperclip into the system off button located on the

bottom of the OmniBook.

To reset the OmniBook

If Windows or the OmniBook stops responding, you can reset the OmniBook and restart Windows.

1. If possible, shut down Windows.

2. Press and hold the blue power button until the display shuts down. –or, if this fails– Insert a pen or straightened paper clip into the system off button located on

the bottom of the OmniBook.

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

Operating the OmniBook XE2

Managing Battery Power

The OmniBook conserves power by using Advanced Power Management (APM), software that controls battery charging and power drain.

The OmniBook provides several safeguards so you won’t be surprised by a dead-battery condition, including the following:

♦ The battery status indicator shows the remaining battery charge. ♦ Built-in warnings are displayed for low battery conditions. ♦ The OmniBook automatically turns off when the battery charge gets too

low —your session continues when you start recharging the battery or insert a fresh battery.

Data on any of the drives is not affected by a low battery—unless the battery runs down completely while writing data to the drive, or if the battery in a PC RAM card is also low.

The OmniBook uses Advanced Power Management (APM) to conserve battery power. You can take steps to optimize your battery operating time. This section describes how to

♦ Save battery power. ♦ Set time-outs. ♦ Get the most from your battery. ♦ Create the hibernation partition.

To save battery power

Follow these suggestions to conserve battery power.

• Plug in the ac adapter, especially while using the floppy disk drive, the

CD-ROM drive, or any external connections.

• Put the OmniBook in Suspend mode whenever you are not using it for a

short while: press the blue power button for approximately 1 second, or select Start menu, Suspend.

• Put the OmniBook in Hibernate mode whenever you want to save your

current session, but will not be using the computer for several hours or more (Fn+F12).

• Shut down the OmniBook whenever you will not be using it for several

hours or more. Click Start, Shut Down. The current session is not saved.

• Turn the brightness of the display down to the lowest comfortable level.

This reduces the backlight power and extends the life of your OmniBook display.

• Set the automatic time-out settings to emphasize saving power.

• If you work with an application that uses the serial port or a PC Card, exit

the application when you are done using it.

2-11

Operating the OmniBook XE2

Managing Battery Power

• If you have an I/O PC Card—that is, a PC Card having an external

connection, such as a modem or network card—remove it when you are not using it. Some I/O cards use significant power, even while they’re inactive.

To set time-outs

The BIOS Setup utility includes settings for automatic time-outs at specified periods of inactivity. There are four different time-outs for different levels of power and conservation.

1. From the Start menu, shut down then restart the OmniBook.

2. When you see the HP logo, press F2 to enter the BIOS Setup utility. Active

keys are described along the bottom of the screen. Help information for the highlighted item appears in the right-hand sidebar in the display.

3. Select the Power menu.

4. Select Power Management Settings.

5. Press F10 to save and exit the BIOS Setup utility.

To get the most from your battery

The following are some further suggestions for the best management of your OmniBook batteries.

• Do not leave batteries unused for long periods of time. If you have more

than one, rotate them.

• If you normally use ac power, make a practice of at least once a week using

the battery as your power source.

• Unplug the ac adapter when the computer is not in use.

• To preserve the life of your battery, be sure to charge the battery regularly.

• For long-term storage, the battery must be charged at 20-50% to save

capacity loss by self-discharge and to avoid deterioration of battery performance. In a discharged condition, the battery voltage decreases faster. Storage in a 100% charged condition can cause higher self-discharge and deterioration of discharge capacity—even after recharging—compared to storage in a 20-50% charged condition.

To create a Hibernate partition

There must be a hibernation partition large enough to hold the contents of memory on the hard disk before the OmniBook can hibernate. By default the hibernation partition is large enough to hold the maximum amount of memory

Managing Battery Power

allowed in the OmniBook. If you have repartitioned the hard disk, purchased a new hard disk, or would like to make the partition smaller, follow the instructions below.

CAUTION

This procedure erases the hard disk. Be sure to save any data on your hard disk before starting this procedure.

You’ll need the OmniBook, its CD-ROM drive, and the OmniBook Recovery CD to create a hibernate partition.

1. Connect the ac adapter to the OmniBook.

2. Insert the bootable Recovery CD in the CD-ROM drive.

3. Reboot, press ESC twice and select the ATAPI CD-ROM as the boot

device.

4. When prompted, click “2 Continue”

5. Click “2 Advanced”. Choose the desired hibernation partition size.

6. Select Do not load operating system.

7. Click “1 Continue”.

8. Click OK.

Do not interrupt the Hibernate partition process or unplug the ac

adapter until the process is complete.
