UMA models:
a. Following the 1, 2, 3, 4 sequence stamped into the heat sink, loosen the four Phillips
PM2.0×4.5 screws (1) that secure the heat sink to the system board.
b. Remove the heat sink (2).
NOTE: Due to the adhesive quality of the thermal material located between the heat sink
and the system board components, it may be necessary to move the heat sink from side to
side to detach it.
NOTE: The thermal material must be thoroughly cleaned from the surfaces of the heat
sink and the system board components each time the heat sink is removed. Replacement
thermal material is included with the heat sink, processor, and system board spare part kits.
NOTE: For UMA models, thoroughly clean thermal material from the surfaces of the system
board components each time you remove the heat sink. Thermal paste is used on the processor
(1) and the heat sink section (2) that services it. All heat sink and processor spare part kits
include thermal material.
