To prevent damage to the notebook, a removable drive, or loss of information, observe the following precautions:

– Before removing or inserting a hard drive, shut down the notebook. If you are unsure whether the notebook is off or in hibernation, turn the notebook on, and then shut it down through the operating system.

– Before removing a diskette drive or optical drive, ensure that a diskette or disc is not in the drive and ensure that the optical drive tray is closed.

– Before handling a drive, ensure that you are discharged of static electricity. While handling a drive, avoid touching the connector.

– Handle drives on surfaces covered with at least one inch of shock-proof foam.

– Avoid dropping drives from any height onto any surface.

– After removing a hard drive, an optical drive, or a diskette drive, place it in a static-proof bag.

– Avoid exposing a hard drive to products that have magnetic fields, such as monitors or speakers.

– Avoid exposing a drive to temperature extremes or liquids.

Use the following grounding precautions when packaging and transporting equipment:

– To avoid hand contact, transport products in static-safe containers, such as tubes, bags, or boxes.

– Protect all electrostatic-sensitive parts and assemblies with conductive or approved containers or packaging.

– Keep electrostatic-sensitive parts in their containers until the parts arrive at static-free workstations.

– Place items on a grounded surface before removing items from their containers.

– Always be properly grounded when touching a sensitive component or assembly.

– Store reusable electrostatic-sensitive parts from assemblies in protective packaging or nonconductive foam.

– Use transporters and conveyors made of antistatic belts and roller bushings. Ensure that mechanized equipment used for moving materials is wired to ground and that proper materials are selected to avoid static charging. When grounding is not possible, use an ionizer to dissipate electric charges.
