62 Chapter 5 Last, but Not Least
Carrying your MacBook If you carry your MacBook in a bag or briefcase, make sure
that there are no loose items (such as paper clips or coins) that could accidentally get
inside the computer through vent openings or the optical drive slot or get stuck inside
a port. Also, keep magnetically sensitive items away from the MagSafe power port.
Using connectors and ports Never force a connector into a port. When connecting a
device, make sure the port is free of debris, that the connector matches the port, and
that you have positioned the connector correctly in relation to the port.
Using the optical drive The SuperDrive in your MacBook supports standard 12 cm
(4.7 inch) discs. Irregularly shaped discs or discs smaller than 12 cm (4.7 inches) are not
supported and can become lodged in the drive.
Storing your MacBook If you are going to store your MacBook for an extended
period of time, keep it in a cool location (ideally, 71° F or 22° C) and discharge the
battery to 50 percent. When storing your computer for longer than five months,
discharge the battery to approximately 50 percent and then remove it from your
MacBook. To maintain the capacity of the battery, recharge the battery to 50 percent
every six months or so.
Cleaning your MacBook When cleaning the outside of your MacBook and its
components, first shut down your MacBook, unplug the power adapter, and remove
the battery. Then use a damp, soft, lint-free cloth to clean the computer’s exterior.
Avoid getting moisture in any openings. Do not spray liquid directly on the computer.
Do not use aerosol sprays, solvents, or abrasives that might damage the finish.
