Introduction
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 device 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.
