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 dis-
charge can damage computer components without causing any signs of physical
damage. You must take extra care in handling them to ensure against electro-
static build-up.
1. To prevent electrostatic build-up, leave the system board in its anti-static bag
until you are ready to install it.
2. Wear an antistatic wrist strap.
3. Do all preparation work on a static-free surface.
4. Hold the device only by its edges. Be careful not to touch any of the compo-
nents, contacts or connections.
5. Avoid touching the pins or contacts on all modules and connectors. 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, establish 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 instal-
lation 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 manufac-
turer.
• Dispose of used batteries according to local ordinance.
