Note: Selected Lenovo computers are low blue-light certified. All certified models, with night light turned on
and the color temperature set to 69, are tested to be compliant with TÜV Rheinland Low Blue Light
requirement.
Avoid constant body contact with specific hot sections
CAUTION:
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 1 minute at a time. As such, it is recommended that users avoid prolonged direct contact with the
bottom of the computer.
