115 - Troubleshooting
Possible Solutions
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.
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.
Make sure you select Save Changes And Exit when exiting
the BIOS setup utility.
Contact your support representative for repairs. This is not a
user serviceable part but has a normal life of 3 to 5 years.
Check the Status Indicator Panel for presence of the Security
icon. If it is visible, enter your password See "Status Indicator
Panel" on page 30.
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.
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)
