Safety: Battery Precautions
This computer contains an internal-only battery that is serviceable by Apple-authorized service
providers only. Tamper-proof screws are employed to prevent customers from attempting to
remove it.
WARNING: Every time you remove the bottom case, disconnect the battery cable from the
logic board.
WARNING: Because the battery is internal and connected to the logic board by a cable, it MUST
BE DISCONNECTED before performing service procedures. If you fail to do so, live current from
the battery will short circuit the components and render the logic board and/or LVDS cable
unusable.
