Apple MacBook Pro (15-inch) - Manual (Page 107)

Appendix B Safety, Use, and Care Information 107
The power adapter may become hot during normal use of your MacBook Pro. Always
allow adequate ventilation around the adapter and use care when handling during or
immediately after operation.
Never force a connector into a port. Check for obstructions on the port. If the
connector and port don’t join with reasonable ease, they probably don’t match. Make
sure that the connector matches the port and that you have positioned the connector
correctly in relation to the port.
If debris gets into the power adapter port, it can prevent the power adapter from
seating properly. Remove debris gently with a cotton swab.
Using Your MacBook Pro
When you’re using your MacBook Pro or charging the battery, it is normal for the
bottom of the case to get warm. For prolonged use, place your MacBook Pro on a flat,
stable surface.
Do not leave the bottom of your MacBook Pro in contact with your lap or any surface
of your body for extended periods. Prolonged contact with your body could cause
discomfort and potentially a burn.
The bottom of the MacBook Pro case functions as a cooling surface that transfers heat
from inside the computer to the cooler air outside. The bottom of the case is raised
slightly to allow airflow that keeps the unit within normal operating temperatures.
In addition, warm air is vented from the slots in the back of the case.
