Setting Up Your MacBook and Power Adapter
Ensure the AC plug or AC power cord is fully inserted into the power adapter before
plugging the adapter into a power outlet. For best results, connect the adapter using
the AC power cord and use a grounded power outlet.
Use only the power adapter that came with your MacBook. Adapters for other
electronic devices (including MacBook Pro models and other portable computers)
might look similar, but they can negatively affect your computer’s performance or
damage your computer.
The power adapter may become hot during normal use of your MacBook. Always allow
adequate ventilation around the adapter and use care when handling it during or
immediately after operation. When possible, place the power adapter on a hard flat
surface to dissipate the heat.
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.
