Notes
  1. Power consumption data (Watts) is measured from the wall power source and includes all power supply and system losses. Additional correction is not needed.
  2. "CPU Max" is defined as running a compute-intensive test application that maximizes processor usage with battery in charge mode and is therefore maximum power consumption of the computer plus losses of the power adapter.
  3. These numbers reflect power adapter maximum power consumption operating within ambient temperature range of 50° F to 95° F (10° C to 35° C).
