Circuit boards and soldered parts of internal options are exposed and
can be damaged by static electricity. Always discharge static build-up
(e.g. by touching a grounded object) before handling electrostatic-
sensitive devices (ESDs).

Do not touch the circuitry on boards or soldered parts. Hold circuit
boards by their metallic areas or edges.

When removing or installing CPUs, be careful not to touch or bend
the spring contacts on the CPU sockets.
