Image Backup and Recovery Procedures
Windows 10 Procedures
It is very important that you create your Recovery Drive before beginning to use your system.
It is also important that you create a backup of the content of the C:\Drivers folder on
your system to writable media or an external drive. System-specific software drivers
are also available for download through the Fujitsu support site.
Note: Most of the information below comes from the Microsoft® page
"http://windows.microsoft.com/en-us/windows-10/windows-10-recovery-options".
Please refer to it for more details.

Possible Cause
The WLAN device was
deactivated or is disabled
The computer to be connected
is turned off
Incorrectly configured network
settings
RF interference from Access
Points or other wireless
networks
Wireless network authentication
has failed
Incorrect IP address
configuration
Possible Solution
Check if the wireless switch is
turned On. Open Control Panel
- Hardware and Sound - Windows
Mobility Center. If the wireless
network is off, click the Turn
wireless on button.
Check if the computer to be
connected is turned ON.
Recheck the configuration of
your network settings.
The use of identical or
overlapping RF channels can
cause interference with the
operation of the WLAN device.
Change the channel of your
Access Point to a channel
that does not overlap with the
interfering device.
Re-check your Network
Authentication, Encryption,
and Security settings.
Incorrectly configured
security settings such as
an incorrectly typed WEP
key, a mis-configured LEAP
username, or an incorrectly
chosen authentication method
will cause the LAN device to
associate but not authenticate
to the wireless network.
This only applies to networks
using static IP addresses.
Please contact your network
administrator for the correct
settings.
