C UTION:
When the computer is operating, it should be placed on a hard and flat surface with its bottom area
not in contact with user’s bare skin. Under normal operating conditions, the temperature of the
bottom surface will remain within an acceptable range as defined in IEC 62368-1, but such
temperatures can still be high enough to cause discomfort or harm to the user if directly touched for
over xx at a time. s such, it is recommended that users avoid prolonged direct contact with the
bottom of the computer.
Note: Some enovo computers include a display that can be rotated 360 degrees. When those products are
used as a tablet computer, the temperatures of all the accessible parts are within an acceptable range as
defined in IEC 62368-1.
