Why did my screen go blank?
❑ Your computer screen may go blank if the computer loses power or enters a power saving mode (Sleep or Hibernate). If
the computer is in LCD (Video) Sleep mode, press any key to bring the computer back into Normal mode. See Using the
Power Saving Modes (page 124) for more information.
❑ The power switch may be in the HOLD position. Slide up the power switch (in the direction of f on the switch) to release
the switch.
❑ Make sure your computer is securely plugged into a power source and turned on. Make sure the power indicator shows
the power is on.
❑ If your computer is using battery power, make sure the battery pack is installed properly and is charged. See Using the
Battery Pack (page 26) for more information.
❑ If the display mode is set to the external display, select on VAIO Touch Launcher.
Why can't I view the whole screen image of a DVD video on my TV screen?
The screen resolution may not be properly set. We recommend that you adjust the screen resolution to 1024 x 768 or smaller,
depending on the size of your external display screen.
How do I adjust the image on my TV screen?
Use the controls on your external display to adjust the image. See the manual that came with your TV for more information.
