Static Electricity Precautions
It is quite easy to inadvertently damage your PC, system board, components or devices even before installing them in your system unit. Static electrical discharge can damage computer components without causing any signs of physical damage. You must take extra care in handling them to ensure against electrostatic

4.Hold the device only by its edges. Be careful not to touch any of the components, contacts or connections.
5.Avoid touching the pins or contacts on all modules and connec- tors. Hold modules or connectors by their ends.
Important:
Electrostatic discharge (ESD) can damage your processor, disk drive and other components. Perform the upgrade instruction procedures described at an ESD workstation only. If such a station is not available, you can provide some ESD protection by wearing an antistatic wrist strap and attaching it to a metal part of the system chassis. If a wrist strap is unavailable, estab- lish and maintain contact with the system chassis throughout any procedures requiring ESD protection.
Safety Measures
To avoid damage to the system:
• Use the correct AC input voltage range.
To reduce the risk of electric shock:
•Unplug the power cord before removing the system chassis cover for installation or servicing. After installation or servicing, cover the system chassis before plugging the power cord.
Battery:
•Danger of explosion if battery incorrectly replaced.
•Replace only with the same or equivalent type recommend by the manufacturer.
•Dispose of used batteries according to local ordinance.
