Preca ut i on s

This section describes certain situations that could cause serious loss of data.

Do not remove a data storage PC Card while it is actively reading or writing. This could cause its data
to become corrupted .

Certain applications, such as Intuit's Quicken, keep their working files open, and they update the files as
you make changes. For such applications, you should open only files that reside on the hard drive, not
on a removable disk. An open file on a removable disk (such as a floppy disk or PC Card) is susceptible
to corruption in certain situations.

Before suspe nding , dock ing, or un docki ng your OmniBook, a lways sa ve your data and close any
applications you have open, especially applications that are not power aware, audio and video
applications, and applications using PC Cards and I/O devices such as a CD-ROM drive.

Replacing Batteries

A newly installed OmniBook battery can take up to 3 seconds to provide power to the OmniBook. To
pr e vent loss of p ower to the OmniBook, wait at least 3 seconds after inserting the battery to disconnect
ac power or to remove a second battery.

Using a Pointing Device During Rebooting and Resuming

While the O mniBook is rebooting, resuming ( turning itse lf on after sus pens ion), starting Windows, or
exiting Windows, do not touch the OmniBook poin ting de vices or an attached external pointing device.
This may result in the pointing device not functioning. Wait until the screen is stabilized and the hour
glass ceases to appear. If the pointing device is not functional, try the following steps, in this order, until
it is functional.

1. Press any key on the keyboard.

2. S uspend t he OmniBook and then r e s ume i t (press the power button br iefly to suspe nd, then pres s th e
button again to resume).

3. S hut down Windows, then turn the Om niBook off and on ( Start men u, Shut down, Restart the
computer).

Synchronizing an External Display or Projector

If you connec t an ext ernal disp lay, projec tor, or proje c tion panel to the Om niBook dis play output, and
its image is not stable, try one of the following ways to deal with display resolution differences:

* Use a display or projector that matches the resolution of the OmniBook disp lay.

* Change t he Display Pr operties of the O mniBook t o match the resolution of the projector or external

display: In Control Panel, Display, Settings, change the Desktop Area to 800 by 600 pixels, 640 by
480 pixels, or 1024 by 768 pixels.

* Turn off the Om niBook 's display and r e tain the external display by pressing Fn+F5, as needed.

Smart CPU Mode (BIOS Setup Utility)

Smart CPU mode should always be set to Off. It is not needed with power-managed systems such as
OmniBook s and can interfer e with some time-sensitive operations, such as downloading files via
modem. Smart CPU mode is automatically set to Off by the default Power Management setting,
Maximum Power Saving.

Using an Older Microsoft Mouse Model

The OmniBook c annot use Suspend mode with two of M icrosoft's older mouse models (parts #28898
and #07685). Th e suspend an d resume activity causes the OmniBook to lock u p with these mice. If you
are using one of these mice, do the following to prevent this problem:

1. Open the BIOS Setup utility (reboot, then pres s F2).

2. In the Power menu, disable the setting for Resume on Serial Ring.

3. Save and exit the Setup utility.

Using Microsoft or Logitech PS/2 Mice with a Scrolling Button

The current drivers for the a bove scroll button mi c e reac t di fferentl y to docki ng and s uspend/res ume
events.

* To ensure that you are always able to use the scroll button:

- Leave the PS/2 Devices setting in the BIOS setup utility on Auto.

- If the MS mouse is attached to the OmniBook while the O mniBook is ru nn ing or in suspend m ode,
reboot the OmniBook to enabl e the s c roll button.

* If the MS mouse is attached to a dock, docking the OmniBook while it is runn ing, i n sus pend mode , or

off enables scrolling.

* If the Logitech mouse is attached to the OmniBook while the O mniBook i s running, t he OmniBook

must be suspended and resumed to enable scrolling.

* If the Logitech mouse is attached to a dock, the OmniBook mu st be su spended and resumed after it is

hot d ocked .

* Dock ing the OmniBook whi le it is suspended will enable the scroll button for both mice.

Check with your vendor for updated drivers for these scroll button mice.
