When switching to a different user with the Fast User Switching function, the
following problems may occur. We recommend you not to use the Fast User
Switching function.
• Some applications may not work properly.
• The display settings may not be possible.
• Wireless LAN cannot be used.
• Bluetooth cannot be used.
In these cases, log off all users without using Fast User Switching function and
perform the operation once more. If the problem persists, restart the computer.
Do not use a 3D screen-saver.
Press [ ] button to open Task Manager, then close the software application.
An input screen (e.g., password input screen at startup) may be hidden behind
another window. Use Alt +Tab to check.
Shut down by pressing and holding the power switch for 4 seconds or longer,
and turn on the computer and open the application again. If Windows runs cor-
rectly, but the application software does not start, click [start] - [Control Panel] -
[Add or Remove Programs] and remove the failing application software, then
reinstall the application software.
