Why does the System Properties window display a slower CPU speed than the
maximum?
This is normal. Because your computer's CPU utilizes a type of CPU speed controlling technology for power conservation
purposes, System Properties may display the current CPU speed instead of the maximum speed.
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.
❑ If the docking station is connected to your computer, do any of the following:
❑ Select Computer Display mode as the graphics mode to display images on the computer screen
(page 139) .
❑ Select External Display mode and change the settings for the display output destination to display images only on the
external display(s) connected to the docking station (page 139) .
