Tips on using your computer in the tablet mode
To close the computer display, first make sure that the display either faces the keyboard or is
positioned at 180 degrees to the keyboard, so that the back of the display faces the keyboard.
Do not pick up or hold the computer by the display only.
Do not hit, vibrate, or bump the computer display.
To allow free ventilation, do not place any obstacle, such as a thick-piled carpet or a soft cushion,
in front of the fan.
When you use the computer in the picture frame mode, hold the display with one hand and use
the Tablet Digitizer Pen.
If you hold the computer with one hand while using it in the tablet mode, do not expose it to
excessive vibration, shock, or rotation.
Do not use the computer outdoors. Do not expose it to rain.
If you put your computer in a carrying case, put it into notebook mode and close the display.
