Figure 99: Removing the CPU
Ê Press the three noses in the direction of the arrows (1) and remove the CPU
from the CPU frame (2).
Ê If the CPU and the heat sink may be reused later, thoroughly clean residual
thermal paste from the CPU surface and from the heat sink surface using a
lint-free cloth and store the CPU in a save place.

CAUTION!
CPUs are extremely sensitive to electrostatic discharge and must be
handled with care. After a CPU has been removed from its protective
sleeve or from its socket, place it upside down on a nonconducting,
antistatic surface. Never push a CPU over a surface.
