Before removing or replacing any components, the following procedures must be
completed:
1. Disconnect AC power and any external devices.
2. Remove the battery pack.
3. Remove any PC Cards.
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.
NOTE:
The Compaq Presario 305 Model Portable Computer has several screws
of various sizes which are not interchangeable. Care must be taken
during reassembly to ensure that the correct screws are used in their
appropriate locations. During removal please keep screws with their
associated sub-assembly.
