3.6 Power Consumption
Power measurements were performed to determine bare minimum and likely
maximum power requirements from the board, as well as attached devices, in order to
facilitate power supply rating estimates for specific system configurations.
3.6.1 Minimum Load Configuration
Minimum load refers to the power demand placed on the power supply when using a
bare system configuration with minimal power requirement conditions. Minimum load
configuration test results are shown in Table 32. The test configuration was defined as
follows:
2 GB DDR3/1066 MHz SO-DIMM
USB keyboard and mouse
LAN linked at 1000 Mb/s
DOS booted via network (PXE); system at idle

3.6.2 Maximum Load Configuration
Maximum load refers to the incremental power demands placed on the power supply,
augmenting the minimum load configuration into a fully-featured system that stresses
power consumption from all subsystems. Maximum load configuration test results are
shown in Table 33. The test configuration was defined as follows:
4 GB DDR3/1066MHz SO-DIMM
14.1-inch LCD via LVDS
SATA DVD-R/W
Load: DVD playback
3.5-inch SATA hard disk drive, running Microsoft Windows Vista Home Basic
Load: continuous read/write benchmark
