of the setup utility are not

compatible with your configu-

ration.

Set the operating source by pressing the [ESC] key while the

Fujitsu logo is on screen or use the [F2] key and enter the

setup utility and adjust the source settings from the Boot

menu. See “BIOS Setup Utility” on page 73.

Use the BIOS setup utility to try to auto detect the internal

hard drive.

played on the screen dur-

ing the boot sequence.

See the Power On Self Test (POST) messages to determine

the meaning and severity of the problem. Not all messages

are errors; some are simply status indicators. See “Power On

Self Test Messages” on page 118.

Your Tablet PC appears to

change setup parameters

when you start it.

saved when made and you

exited the setup utility.

Make sure you select Save Changes And Exit when exiting

the BIOS setup utility.

tery has failed.

Contact your support representative for repairs. This is not a

user serviceable part but has a normal life of 3 to 5 years.

turn on when the system is

turned on or has resumed.

You have installed the LIFE-

Panel” on page 30.

Video Problems

The built-in display is blank

when you turn on your

LIFEBOOK Tablet PC.

Display angle and brightness

settings are not adequate for

your lighting conditions.

Move the display and the brightness control until you have

adequate visibility. Pressing either the [F6] or [F7] keys while

holding down the [Fn] key also allows you to change the

brightness level of the display.

Power management timeouts

are set for short intervals and

you didn’t see the display go

on and off again.

Press a keyboard button or move the mouse to restore oper-

ation. If that fails, push the Power/Suspend/Resume switch.

(The display may be shut off by Sleep mode, Auto Suspend

or Video Timeout)
