Preparing the Notebook for Disassembly

Before beginning the removal or replacement of any Notebook components, complete the following steps:

1.Disconnect AC power source and any external devices.

2.Disconnect the Notebook from the QuikDock (pg 11).

3.Remove any PC cards.

4.Remove the battery pack (pg 12).

Important: The battery pack should be removed before performing any internal maintenance on the Notebook.

ÄCAUTION: 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 1800 Series Notebooks in the battery compartment. Do not force the battery pack into the bay if insertion is difficult.

ÄCAUTION: Do not crush, puncture, or incinerate the battery pack. Do not open a battery pack; this damages the pack, makes it unusable, and exposes potentially harmful battery components. No field-serviceable parts are located inside the battery pack.

Note: The Compaq Presario 1800 Series Notebooks have several screws of various sizes that are not interchangeable. Care must be taken during reassembly to ensure that the correct screws are used in their correct locations. During removal, keep screws with their associated subassembly.

Important: As each component is removed from the Notebook, place the it together with its screws away from the work area to prevent damage.
