Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside your computer. To prevent static damage,
discharge static electricity from your body before you touch any of your computer’s electronic
components, such as the microprocessor. You can do so by touching an unpainted metal surface
on the computer chassis.
As you continue to work inside the computer, periodically touch an unpainted metal surface to
remove any static charge your body may have accumulated.
You can also take the following steps to prevent damage from electrostatic discharge (ESD):
• Do not remove components from their antistatic packing material until you are ready to install
the component in your computer. Just before unwrapping the antistatic packaging, discharge
static electricity from your body.
• When transporting an electrostatic sensitive component, first place it in an antistatic container
or packaging.
• Handle all electrostatic sensitive components in a static-safe area. If possible, use antistatic floor
pads and workbench pads.
Battery Disposal
Your computer uses a lithium coin-cell battery. The lithium coin-cell battery is a long-life battery, and it
is very possible that you will never need to replace it. However, should you need to replace it, see your
User’s Guide .
Do not dispose of the battery along with household waste. Contact your local waste disposal agency
for the address of the nearest battery deposit site.
