For this mode, the systemCPU was stressed at 90% utilization with no other peripheral device actively seeking. This test mode is not specified in ISO 7779, butwas measured using the same microphone distances and measurement techniques defined for the other reported operating modes.6 Declared Sound Power rounded to the nearest tenth of a bel per ISO 9296 section 4.4.23 Declared Sound Pressure rounded to the nearest whole decibel per ISO 9296 section 4.4.4Operating ModeHigh-end ConfigurationDeclared Sound Power (LWAd)Typical ConfigurationDeclared Sound Power (LWAd)EcoKit ConfigurationDeclared Sound Power (LWAd)Idle 3.9 3.5 3.0HDD Operating 4.0 3.4 3.0ODD Operating 4.8 4.8 4.890% CPU 4.6 3.4 3.1Operating ModeHigh-end ConfigurationSound Pressure at OperatorPosition (LpA)Typical ConfigurationSound Pressure at OperatorPosition (LpA)EcoKit ConfigurationSound Pressure at OperatorPosition (LpA)
