Abstract
Disclosed are systems and methods for determining when a heat sink is installed. In one embodiment, a system comprises an electrically-conductive heat sink retainer clip that is adapted to maintain contact between a heat sink and a heat-producing component, the retainer clip further being adapted to electrically connect to ground, and a heat sink detection circuit adapted to provide voltage to the retainer clip, the heat sink detection circuit being configured to provide a logic value that indicates one of presence or absence of a heat sink.
