About this task
NOTE: The heat sink may become hot during normal operation. Allow sufficient time for the heat sink to cool before you
touch it.
NOTE: For maximum cooling of the processor, do not touch the heat transfer areas on the heat sink. The oils in your skin
can reduce the heat transfer capability of the thermal grease.
The following images indicate the location of the UMA heat sink and provide a visual representation of the removal procedure.
Steps
1. Loosen the four captive screws that secure the heat sink to the system board.
NOTE: Loosen the captive screws in the reverse sequential order mentioned on the heat sink [4 > 3 > 2 > 1].
NOTE: The number of screws varies depending on the configuration ordered.
