Warning: Do not place your MacBook Pro on a pillow or other soft material when it is on, as the material can block the airflow vents, in particular the rear vents, and cause the computer to overheat. Never place anything over your keyboard when operating in closed-lid mode. This can cause your computer to cycle on and off which might create excessive heat and drain your battery. Never turn on your computer unless all of its internal and external parts are in place. Operating the computer when it is open or missing parts can be dangerous and can damage your computer. Carrying Your MacBook Pro If you carry your MacBook Pro 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 an opening such as the optical drive slot or get stuck inside a port. Storing Your MacBook Pro If you are going to store your MacBook Pro for an extended period of time, keep it in a cool location (ideally, 71° F or 22° C) and do one of the following to preserve your MacBook Pro battery life: Â Discharge the battery 50 percent before storing your MacBook Pro. Â When storing your computer for longer than five months, discharge the battery to approximately 50 percent and then remove it from the MacBook Pro. If you are storing your computer for an extended period, recharge your battery to 50 percent every six months or so. 108 Appendix B Safety, Use, and Care Information
