Static electricity prevention
Static electricity, although harmless to you, can seriously damage computer components and options.
Improper handling of static-sensitive parts can damage the part. When you unpack an option or a CRU,
do not open the static-protective package that contains the part until the instructions direct you to install
the part.
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 that contains 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 in the package and your body.
• When possible, remove the static-sensitive part from the static-protective package and install the part
without setting it down. When this is not possible, place the static-protective package on a smooth,
level surface and place the part on the package.
• Do not place the part on the computer cover or other metal surface.
Disabling the built-in battery
Before replacing any devices, ensure that you have disabled the built-in battery by doing the following:
1. Turn off the computer and disconnect the ac power adapter and all cables from the computer.
2. Turn on the computer. When the ThinkPad logo is displayed, immediately press F1 to enter ThinkPad
Setup.
3. Select Config ➙ Power . The Power submenu is displayed.
4. Select Disable Built-in Battery and press Enter.
5. Select Yes in the Setup Confirmation window. The built-in battery is disabled and the computer turns
off. Wait for a few minutes to let the computer cool.
The built-in battery will be automatically enabled when the ac power adapter is reconnected to the computer.
