WARNING: Metal objects can damage the battery pack as well as the battery contacts in the battery compartment. To prevent damage, do not allow metal objects to touch the battery contacts. Place only the battery pack for the Compaq Presario 305 Model Portable Computers into the battery compartment. Do not force the battery pack into the bay if insertion does not occur easily.
CAUTION: Do not crush, puncture, or incinerate the battery pack. Do not open a battery pack, as this damages the pack, makes it unusable, and exposes potentially harmful battery components. There are no field- serviceable parts located inside the battery pack.
CAUTION: Failure to disconnect the AC Adapter from the computer and remove the battery pack before removing and installing internal components can damage the equipment.
The Compaq Presario 305 Model Portable Computer has several screws of various sizes which are not interchangeable. Care must be taken
NOTE: during reassembly to ensure that the correct screws are used in their appropriate locations. During removal please keep screws with their associated
privacy and legal statement
