Safety Instructions 11
In addition, take note of these safety guidelines when appropriate:
• 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. 
• Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its 
edges or by its metal mounting bracket. Hold a component such as a microprocessor chip by its edges, not by 
its pins.
  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.
SAFETY: 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.
SAFETY: Ergonomic Computing Habits 
  CAUTION: Improper or prolonged keyboard use may result in injury.
 
CAUTION: Viewing the monitor screen for extended periods of time may result in eye strain.
For comfort and efficiency, observe the ergonomic guidelines in the

 help file when setting up and using your 
computer. To access the help file, see page 32.
SAFETY: 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 page 110.
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.
