Computer Operations
Why doesn't my computer enter Sleep mode?
Your computer may become unstable if the operating mode is changed before the computer completely enters Sleep mode.
To restore your computer to normal mode
1 Close all open programs.
2 Click Start, the arrow next to the Shut down button, and Restart.
3 If your computer does not restart, press the Ctrl+Alt+Delete keys and click the arrow next to the Shut down button and
Restart.
4 If this procedure does not work, press and hold the power button until the computer turns off.
!
Turning off your computer with the Ctrl+Alt+Delete keys or the power button may cause loss of unsaved data.
What should I do if my computer does not accept my password and returns a message,
Enter Onetime Password?
If you enter a wrong power-on password three times consecutively, the Enter Onetime Password message appears and
Windows will not start. Press and hold the power button for more than four seconds to check that the power indicator light
turns off. Wait for 10 to 15 seconds, then restart your computer and enter the correct password. The password is case
sensitive, so be sure to check letters for the current case before you enter the password.
What should I do if my game software does not work or it keeps crashing?
❑ Check the web site of the game if there are any patches or updates to download.
❑ Make sure you have installed the latest video driver software.
❑ On some VAIO models, the graphics memory is shared with the system. The optimal graphic performance in such a case
is not guaranteed.
