2. Turn off your computer and any devices connected to the computer.
3. Ground yourself by touching an unpainted metal surface on the chassis before touching anything inside your computer.
While you work, periodically touch an unpainted metal surface on the computer chassis to dissipate any static electricity that might harm internal
components.
4. Disconnect your computer and devices, including the monitor, from their electrical outlets. Also, disconnect any telephone or telecommunication lines
from the computer.
Doing so reduces the potential for personal injury or shock.
In addition, take note of these safety guidelines when appropriate:
l When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector with locking tabs;
if you are disconnecting this type of cable, press in on the locking tabs before disconnecting the cable. As you pull connectors apart, keep them evenly
aligned to avoid bending any connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented and aligned.
l Handle components with care. Hold a component such as a microprocessor chip by its edges, not by its pins.
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):
l 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.
l When transporting an electrostatic sensitive component, first place it in an antistatic container or packaging.
l Handle all electrostatic sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads.
CAUTION: There is a danger of a new battery exploding if it is incorrectly installed. Replace the battery only with the same or equivalent type
recommended by the manufacturer. 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.
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 "Replacing the Battery" in the GX270 Systems 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.
