11.3 Replacing a CPU or heat sink
V CAUTION!
CPUs are modules which are extremely sensitive to electrostatic
discharges and therefore must always be handled with care. After a CPU
has been removed from its protective sleeve or from its socket, place it
with its smooth side down on a non-conducting, antistatic surface. Never
push a CPU over a surface.
