What should I do if the touch screen does not work correctly? (Touch screen equipped models)
Turn off your VAIO computer, and then turn it on again.
Electromagnetic waves may cause the touch screen to work incorrectly. Try these suggestions.
Move your VAIO computer away from a fluorescent light or a motor that emits electromagnetic waves.
Connect the AC adapter directly to an AC outlet or use other outlets if you are using a power strip.
Remove any USB device or cable connected to your VAIO computer, if any.
If your AC adapter has a 3-pin plug, make sure it is properly grounded.
What should I do if I cannot use NFC/One-touch functions?
Bring your NFC/One-touch functions supported device toward your VAIO computer as close as possible.
If the NFC/One-touch functions still do not work, slightly move the device up or down, or separate the
device from the computer for about 10 seconds, and then touch the computer with the device again.

computer.
Why do sound interruptions and/or dropped frames occur when I play high-definition videos, such as those
recorded with the AVCHD digital video camcorder?
Playing high-definition videos requires substantial hardware resources, such as CPU, GPU, or system
memory performance on your VAIO computer. During the video playback, some operations and/or functions
may become unavailable, and sound interruptions, dropped frames, and playback failure may occur
depending on the configuration of the computer.
