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 or less. When storing your MacBook for longer than five months,
discharge the battery to approximately 50 percent. 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 and unplug the power adapter. 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.
Cleaning the MacBook screen To clean the MacBook screen, first shut down your
MacBook and unplug the power adapter. Then dampen a clean cloth with just water
and wipe the screen. Do not spray liquid directly on the screen.
