Heat sink
Description
For use only on computer models equipped with AMD processors and UMA graphics
NOTE:
To properly ventilate the computer, allow at least 7.6 cm (3 in) of clearance on the left side of

sensor and is designed to turn on automatically when high temperature conditions exist. These conditions
are affected by high external temperatures, system power consumption, power management/battery
conservation configurations, battery fast charging, and software requirements. Exhaust air is displaced
through the ventilation grill located on the left side of the computer.
Before removing the heat sink, follow these steps:
1.
Shut down the computer. If you are unsure whether the computer is off or in Hibernation, turn
the computer on, and then shut it down through the operating system.
