Preparing your work space
Preparing your work space
Before performing maintenance on your notebook, make sure that your work space and your notebook are prepared correctly.
I I I I I I I I
Wear a grounding (ESD) wrist strap. Use a grounded or dissipative work mat. Use a stable and strong table. Make sure that the table top is large enough to hold each component as you remove it. Use bright lighting to make part identification easier. Keep your work surface free from clutter and dust that may damage components. Use a magnetized screwdriver for removing screws. As you remove components and screws, lay them toward the rear of your work surface (behind your notebook) or far enough to the side that your arms do not accidentally brush components onto the floor. To help keep track of screws, try the following:
I
I
Place each component's screws in their own section of a parts sorter. Place each component's screws next to the component on your work surface. Print the first page of each task, then place the page toward the rear of your work surface. As you remove screws, place the screws in their respective boxes on the page. Where screw measurements are shown, the first number indicates screw head width, and the second number indicates screw length. After loosening screws that are deeply recessed in a hole (for example, on the bottom of the base assembly or on the cooling assembly), you can leave the screws in the holes if you place small pieces of tape over the hole openings. When reassembling the component, just remove the tape and tighten the screws. When you place flat-headed screws on your work surface, stand them on their heads to prevent the screws from rolling off the table.

Preventing static electricity discharge
The components inside your notebook are extremely sensitive to static electricity, also known as electrostatic discharge (ESD).
Caution ESD can permanently damage electrostatic discharge sensitive components in your notebook. Prevent ESD damage by following ESD guidelines every time you open your notebook case.
Warning
To avoid exposure to dangerous electrical voltages and moving parts, turn off your notebook, remove the battery, and unplug the power cord and modem cable before opening the case.
Before replacing components, follow these guidelines:
I I I I
Turn off your notebook power. Remove the battery and unplug the power cord. Disconnect all peripheral devices and remove any PC Cards. Wear a grounding wrist strap (available at most electronics stores) and attach it to a bare metal part of your workbench or other grounded connection. Touch a bare metal surface on your workbench or other grounded object. Avoid static-causing surfaces such as carpeted floors, plastic, and packing foam. Remove components from their antistatic bags only when you are ready to use them. Do not lay components on the outside of antistatic bags because only the inside of the bags provide electrostatic protection. Always hold memory modules and modems by their edges, but avoid touching the edge connectors and components on the cards. Never slide any component over any surface.
Warning To prevent risk of electric shock, do not insert any object into the vent holes of your notebook.
