Why doesn't my screen turn off after the automatic turn-off time has passed?
Some software applications or screen savers are designed to temporarily disable the feature of your operating system that
turns off the computer screen or places the computer into Sleep mode after a certain period of inactivity. To solve this
problem, exit the running software application(s) or change the current screen saver.
What should I do if I cannot boot my computer from the external device connected to the
computer?
To boot your computer from an external device, for example a USB floppy disk drive or a USB optical disc drive, you need to
change the boot device. To change the boot device, turn on your computer and press the
F11
key repeatedly until the VAIO
logo disappears.
!
When using an external device, be sure to connect it to an AC power source in advance.
