Table 49 shows the maximum power consumption for the Intel 82Q45 GMCH in the
ACPI S3, S4, and S5 states with Intel Active Management Technology support.
Platforms that use Intel Active Management Technology will keep DRAM memory
powered in S4 and S5. Current consumption used by the (G)MCH will vary between the
"Idle" case and the "Max" case, depending on activity on the Intel Management Engine.
For the majority of the time, the Intel Management Engine will be in the "Idle" state. It
is unknown if commercial software management applications will be able to generate
this level of power consumption
