Inserting the Primary Battery Pack
CAUTION: If the battery pack you are about to remove is the only source of power to the computer, initiate Hibernation or connect the computer to external power before removing the battery.
Insert a battery pack into the battery bay with the large label on the battery pack facing up and the battery contacts facing in. Push the battery pack into the battery bay until it is firmly seated.
NOTE: See Chapter 5 to insert and remove battery packs to and from the DualBay and MultiBay.
