Chapter 6. Replacing devices This chapter provides instructions on how to install or replace some hardwares for your computer. This chapter contains the following topics: • "Static electricity prevention" on page 71 • "Replacing the battery" on page 72 • "Replacing the SIM card" on page 74 • "Replacing the hard disk drive or solid-state drive" on page 75 • "Replacing a memory module" on page 78 • "Replacing the keyboard" on page 81 • "Replacing the palm rest" on page 84 • "Replacing the wireless LAN/WiMAX card" on page 87 • "Replacing the wireless WAN card" on page 90 • "Replacing the backup battery" on page 92 Static electricity prevention Static electricity, although harmless to you, can seriously damage computer components and options. Improper handling of static-sensitive parts can cause damage to the part. When you unpack an option or CRU, do not open the static-protective package containing the part until the instructions direct you to install it. When you handle options or CRUs, or perform any work inside the computer, take the following precautions to avoid static-electricity damage: • Limit your movement. Movement can cause static electricity to build up around you. • Always handle components carefully. Handle adapters, memory modules, and other circuit boards by the edges. Never touch exposed circuitry. • Prevent others from touching components. • When you install a static-sensitive option or CRU, touch the static-protective package containing the part to a metal expansion-slot cover or other unpainted metal surface on the computer for at least two seconds. This reduces static electricity from the package and your body. • When possible, remove the static-sensitive part from the static-protective packaging and install the part without setting it down. When this is not possible, place the static-protective packaging on a smooth, level surface and place the part on it. • Do not place the part on the computer cover or other metal surface. © Copyright Lenovo 2012 71

Static electricity prevention
Static electricity, although harmless to you, can seriously damage computer components and options.
Improper handling of static-sensitive parts can cause damage to the part. When you unpack an option
or CRU, do not open the static-protective package containing the part until the instructions direct you
to install it.
When you handle options or CRUs, or perform any work inside the computer, take the following precautions
to avoid static-electricity damage:
•
Limit your movement. Movement can cause static electricity to build up around you.
•
Always handle components carefully. Handle adapters, memory modules, and other circuit boards by the
edges. Never touch exposed circuitry.
•
Prevent others from touching components.
•
When you install a static-sensitive option or CRU, touch the static-protective package containing the
part to a metal expansion-slot cover or other unpainted metal surface on the computer for at least two
seconds. This reduces static electricity from the package and your body.
•
When possible, remove the static-sensitive part from the static-protective packaging and install the part
without setting it down. When this is not possible, place the static-protective packaging on a smooth,
level surface and place the part on it.
•
Do not place the part on the computer cover or other metal surface.
