CHAPTER 8: Upgrading Your Notebook

Preventing static electricity
discharge
The components inside your notebook are extremely sensitive
to static electricity, also known as electrostatic discharge
(ESD).
Before installing or replacing components, follow these
guidelines:
• 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 components by their edges. Avoid touching
the edge connectors. Never slide components over any
surface.
• 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.
Warning
To avoid exposure to dangerous electrical voltages and moving parts,
turn off your notebook, unplug the power cord, modem cable, and network
cable, and remove the main and optional secondary batteries before opening
the case.
Warning
To prevent risk of electric shock, do not insert any object into the vent
holes of the notebook.
Important
Before installing or replacing components, you should read and
understand the information in this section.
